Ingredients Explained
Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated!
Learn more about WaterGlycine Soja Oil is a plant-derived oil from soybean seeds. Like other oils, it is rich in essential fatty acids (mostly linoleic and oleic) that support skin hydration and barrier function.
The fatty acids are able to integrate into the lipid matrix of the stratum corneum to help soften skin and reduce water loss.
On top of that, soybean oil is rich in vitamins like vitamin E, a potent antioxidant.
Research on soybean's active components also point to anti-inflammatory, collagen-stimulating, antioxidant activity, and protection against UV-induced oxidative damage.
Most of this research applies to the broader soybean plant and not just the oil fraction alone.
This ingredient may not be fungal acne safe due to the oleic acid content.
Learn more about Glycine Soja OilWe don't have a description for Caprylic/Capric/Myristic/Stearic Triglyceride yet.
Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum.
Topically, glycerin does several things at once:
Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.
Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.
This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.
Just know very high concentrations (>40%) can feel tacky in low humidity.
Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.
Learn more about GlycerinThis ingredient is also known as sweet almond oil. It is a lightweight, cold-pressed oil from the ripe seeds of the sweet almond tree.
Sweet almond oil is rich in skin-nourishing fatty acids such as oleic acid (55-86%) and linolenic acid (7-35%).
As an emollient, it softens and hydrates skin by forming a thin barrier that locks in moisture.
Clinical studies have found it to be non-irritating and non-sensitizing. The CIR Expert Panel has evaluated the available safety data and concluded it is safe for topical use.
Because of the oleic acid content, this ingredient may not be fungal acne safe.
Learn more about Prunus Amygdalus Dulcis OilButylene Glycol (or BG) is used within cosmetic products for a few different reasons:
Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.
Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.
Learn more about Butylene GlycolDimethicone is a type of synthetic silicone created from natural materials such as quartz. It is also known as polydimethylsiloxane.
What it does:
Dimethicone comes in different viscosities:
Depending on the viscosity, dimethicone has different properties.
Ingredients lists don't always show which type is used, so we recommend reaching out to the brand if you have questions about the viscosity.
This ingredient is unlikely to cause irritation because it does not get absorbed into skin. However, people with silicone allergies should be careful about using this ingredient.
Note: Dimethicone may contribute to pilling. This is because it is not oil or water soluble, so pilling may occur when layered with products. When mixed with heavy oils in a formula, the outcome is also quite greasy.
Learn more about DimethiconeStearyl Alcohol is a type of fatty alcohol from stearic acid. It is a white, waxy compound used to emulsify ingredients used as an emollient or to thicken a product.
Emollients help soothe and hydrate the skin by trapping moisture.
Fatty alcohols are usually derived from natural fats and oils and therefore do not have the same drying or irritating effect as solvent (ethanol) alcohols.
The FDA allows products labeled "alcohol-free" to have fatty alcohols.
Learn more about Stearyl AlcoholSteareth-2 is a waxy compound used to emulsify ingredients. It is created from polyethylene glycol and stearyl alcohol. The 2 stands for the number of ethylene oxide units used to create this ingredient.
Due to the low degree of ethoxylation, the molecule stays mostly oil-loving. That's why you'll often see it paired with water-loving steareth-20 or steareth-21 to create elegant emulsions.
In testing, this ingredient was nontoxic in acute oral studies and not a skin irritant or sensitizer.
You might hear concerns about 1,4-dioxane as a byproduct of ethoxylation; this is well-known in the industry and is controlled through purification steps before the ingredient is blended into finished products.
Learn more about Steareth-2This ingredient is also known as coconut oil. It is a plant-derived ingredient with skin conditioning properties.
The fatty acid profile of coconut oil is mostly lauric acid (~54%), followed by capric, caprylic, palmitic, and myristic acids. This profile allows it to penetrate easily into skin, moisturize, and improve dry skin.
A double-blind study confirmed that extra virgin coconut oil is as effective as mineral oil for treating very dry skin. Another study found it outperformed mineral oil for mild to moderate atopic dermatitis in children.
Another study from 2018 found that virgin coconut oil can soothe inflammation and boost key skin barrier proteins. Just know this evidence is still only from lab settings and not human trials.
It has also been shown to reduce Staphylococcus aureus, a bacteria that commonly overgrows in people with eczema.
Clinical testing shows very minimal skin irritation and no evidence of sensitization or phototoxicity.
Coconut oil gets flagged as a "fragrance" because it has a natural mild scent (not because it's a synthetic perfume). The European Cosmetic ingredient database also lists "perfuming" as a function of this ingredient.
Just so you know, the term "fragrance" is completely unregulated. Some brands still use botanical extracts or essential oils in their "fragrance-free" formulas, but regulatory databases technically classify these under "fragrance".
Coconut oil has a tiny and useless bit of natural SPF. Early lab studies clocked it around SPF 7-8 but a more recent study found the real number closer to SPF 1.2. It also offers no meaningful UVA protection (SPF only overs UVB rays).
The comedogenic rating of 4/5 means it has a high potential to clog pores; but it's worth noting that comedogenicity is highly individual and ratings cannot predict how an overall formula will behave on skin.
Since lauric acid is the dominant fatty acid, this ingredient may not be fungal acne safe. The Malassezia yeast feeds on fatty acids with carbon chain lengths between 11-24, and lauric acid falls within these lengths (C12).
Learn more about Cocos Nucifera OilHelianthus Annuus Seed Oil is a plant oil derived from the seeds of a sunflower.
It is rich in fatty acids, primarily linoleic acid and oleic acid. This gives it emollient and skin conditioning properties.
The reason this ingredient is so effective is because it forms a thin film on the skin that reduces transepidermal water loss (TEWL) while supplying linoleic acid to the stratum corneum to improve barrier strength.
The high linoleic acid content is particularly noteworthy for acne-prone skin.
Research suggests that acne-prone skin tends to be deficient in linoleic acid in sebum. Topical application may help replenish this to support a healthier follicular environment and less comedone-promoting sebum.
One randomized study found sunflower seed oil preserved skin barrier integrity in adult volunteers with and without atopic dermatitis (outperforming olive oil).
This ingredient is well-studied, gentle, and an effective emollient suitable for most skin types.
On fungal acne: This ingredient may not be Fungal acne (Malassezia folliculitis) safe. This is because it contains fatty acids with carbon chain lengths in the C11-C24 range.
Learn more about Helianthus Annuus Seed OilGlyceryl Stearate is made by reacting glycerin with stearic acid (typically sourced from plant oils like palm or coconut). It's an emulsifier, emollient, and mild occlusive.
Emulsifiers help ingredients like oil and water stay mixed so your formula stays nicely blended and uniform in texture.
This ingredient is typically used in concentrations between 1-10%. Studies have found it to be non-sensitizing, non-phototoxic, and non-photoallergenic.
A close cousin of this ingredient is Glyceryl Stearate SE ("self-emulsifying"). This just has a small amount of sodium or potassium stearate added so it can emulsify without a co-emulsifier.
Since this ingredient is an ester of a C18 fatty acid, it may not be fungal acne safe. The Malassezia yeast can potentially metabolize within the C11-C24 range.
Fun fact: The human body also creates Glyceryl Stearate naturally.
Learn more about Glyceryl StearateVitis Vinifera Seed Oil comes from the grape vine. Grape seeds are a byproduct of creating grape juice or wine.
The components of grape seeds have many skin benefits. Research has found it to be antimicrobial and anti-inflammatory. It also contains many potent antioxidants such as Vitamin E , Vitamin C, proanthocyanidins, polyphenols, flavonoids, and anthocyanins. Proanthocyanidin has been shown to help even out skin tone.
Antioxidants help fight free-radical molecules. Free-radical molecules are capable of damaging our cells and other genetic material. Antioxidants help stabilize free-radicals by donating extra electrons. Grape seed extract may help reduce the signs of aging.
The antimicrobial properties of grape seed may help treat acne. However, more research is needed to support this claim.
Grape seed has also been found to help absorb UV rays. Grape seed extract should not replace your sunscreen.
The fatty acids of grape seed oil give it emollient properties. Emollients help soothe and soften your skin by creating a film. This film traps moisture within, keeping your skin hydrated.
Learn more about Vitis Vinifera Seed OilPropanediol is an all-star ingredient. It softens, hydrates, and smooths the skin.
It’s often used to:
Propanediol is not likely to cause sensitivity and considered safe to use. It is derived from corn or petroleum with a clear color and no scent.
Learn more about PropanediolSteareth-21 is a nonionic emulsifier made by reacting stearyl alcohol with 21 units of ethylene oxide. It is mainly a cleansing agent and emulsifier.
The "21" in the name just tells you it has a longer water-loving chain. This makes it more gentle and less likely to irritate skin compared to lower-numbered steareths.
You'll most likely see it paired with steareth-2 because the two work together to create stable formulations.
1,4-dioxane is often brought up as a concern but this is usually removed through purification.
Learn more about Steareth-21Limnanthes Alba Seed Oil is the oil extracted from the seeds of the meadowfoam plant. This oil is non-fragrant and is an emollient. As an emollient, meadowfoam seed oil helps soften and hydrate the skin.
Meadowfoam seed oil is stable and has a long shelf life due to its chemical structure. It has the highest concentration of stable fatty-acids among plant oils, preventing it from degrading once exposed to oxygen.
Due to the fatty acid content, this ingredient may not be fungal-acne safe.
Meadowfoam is native to California and Oregon.
Learn more about Limnanthes Alba Seed OilThis ingredient is also known as milk thistle seed oil. It is made by cold pressing the seeds of the milk thistle plant.
The main fatty acids in this oil are linoleic acid (~53%) and oleic acid (~21%). However, its standout compound is silymarin, a powerful antioxidant and skin soother.
Silymarin is best known for protecting skin against UV rays and pollution as an antioxidant. In a clinical study, a formulation containing this ingredient showed improvements in skin elasticity, dermal densitiy, brightness, and a reduction of redness after 4 weeks of use.
Research on the fruit extract found a sustained and significant decrease in acne lesion counts (a ~45% improvement after 6 months and ~59% at 12 months).
Due to its rich fatty acid content, this ingredient may not be fungal acne safe.
Learn more about Silybum Marianum Seed OilHypnea Musciformis Extract comes from the red algae called Hypnea musciformis. Hypnea Musciformis is commonly found in the Atlantic, Pacific, and Indian Oceans.
The cell walls of Hypnea Musciformis is rich in carrageenan.
Hypnea Musciformis Extract contains vitamins A, C, and E. It also has calcium, magnesium, sodium, potassium, and iron.
Learn more about Hypnea Musciformis ExtractOxycoccus Palustris Seed Oil is an antioxidant and is an oil.
Laminaria Ochroleuca Extract is a type of kelp. It helps sooth and hydrate the skin. By nourishing the skin's barrier, it may also help relieve irritation.
This ingredient contains both lipids and antioxidants. The lipids nourish the skin's barrier. Antioxidants help fight free-radicals. Free-radicals are molecules that may damage your skin cells.
This ingredient is good for soothing sensitive skin.
Many different types of algae have different benefits.
Learn more about Laminaria Ochroleuca ExtractOenothera Biennis Oil is the fixed oil derived from the seeds of the Evening Primrose.
Evening primrose oil is rich in fatty acids. These fatty acids include linoleic (60-85%), oleic (5-12%), palmitic (4-10%), and stearic (2-4%).
The fatty acid composition makes it a great ingredient for soothing and moisturizing skin. However, it may not be Malassezia folliculitis, or fungal acne safe.
Further research is needed on the role of evening primrose in treating eczema.
Evening primrose is native to North America.

Narcissus Tazetta Bulb Extract can cause irritation.
This extract comes from cucumber. Cucumbers are mostly made up of water (95%), and the other 5% is composed of: vitamin C, caffeic acid, fatty acids, amino acids, and other minerals.
Cucumbers have anti-inflammatory, barrier repair, and hydrating properties.
They contain shikimate dehydrigenase, an enzyme shown to help reduce inflammation and soothe the skin.
The amino acids found in cucumbers help nourish our skin's natural acid mantle (it's an important part of our skin barrier). This slightly acidic film acts as a barrier to protect us from bacteria, viruses, and other contaminants.
Unless you have an allergy to cucumbers, this is generally a non-irritating ingredient.
Fun fact: Cucumis Sativus is native to South Asia and can now be found on every continent.
Learn more about Cucumis Sativus Fruit ExtractPyrus Malus Fruit Extract is extract from Apples. Apples are rich in Vitamin C, sugars, and antioxidants.
The sugar in Apples are humectants and help hydrate the skin. On top of that, apples also contain some acids, such as malic acid. These acids may have a mild exfoliating effect.
Last, the phytochemicals found in apples are strong antioxidants. These antioxidants help with anti-aging as they protect your skin cells against oxidative damage.
Learn more about Pyrus Malus Fruit ExtractScutellaria Baicalensis Root Extract comes from the Baikal skullcap or Chinese skullcap plant. This plant is native to Northeast Asia and can be found in China, Mongolia, Korea, and Siberia.
In cosmetics, Scutellaria Baicalensis Root Extract provides antioxidant and anti-inflammatory benefits. This is due to the flavonoid composition of Scutellaria Baicalensis Root Extract.
In Chinese traditional folk medicine, Scutellaria Baicalensis Root Extract is used to help treat lung issues and hypertension.
Learn more about Scutellaria Baicalensis Root ExtractThis ingredient is a plant-derived protein made by breaking down wheat proteins into smaller amino acids and peptides. It has skin and hair conditioning properties.
People with known wheat allergy or a history of immediate reactions should be cautious with leave-on products containing hydrolyzed wheat proteins.
Boswellia Serrata Extract is the extract of the whole plant, Boswellia serrata, Burseraceae.
AKA Indian Frankincense Extract
This ingredient is also known as shea butter. It is a plant-derived extract from the nuts of the Africa shea tree and one of the most well-studied emollients.
Because it has a high concentration of fatty acids (primarily oleic, stearic, and linoleic) it is able to form a protective barrier on the skin's surface. This helps seal in moisture and prevents transepidermal water loss (TEWL).
In vitro research found an increase in skin hydration by 58% and a decrease in TEWL by 37.8% after 24 hours of applying this ingredient (pretty impressive for a single ingredient!).
Besides hydration, shea butter also contains triterpenes that have anti-inflammatory potential. In particule, lupeol cinnamate has shown the highest anti-inflammatory activity in vivo.
Shea butter also contains vitamins A and E which may contribute to antioxidant activity.
While Shea Butter has an SPF rating of about 3-4, it is not a sunscreen replacement.
This ingredient may not be fungal acne safe because its fatty acids fall within the C11-C24 range that the Malassezia yeast can metabolize.

Macadamia Integrifolia Seed Oil is the fixed oil obtained from Macadamia nut native to Australia. Due to its similarity with our skin's natural oils, macadamia oil absorbs easily without feeling greasy.
Macadamia seed oil is rich in fatty acids, including oleic acid (45-75%), palmitoleic acid (7-33%), and palmitic acid (6-12%). They also contain various B vitamins, iron, and magnesium.
Palmitoleic acid helps calm inflammation and supports wound healing while oleic acid helps hydrate the skin.
Due to the high amounts of palmitic and oleic acid, this ingredient may not be fungal acne safe. These are fatty acids that Malassezia yeast can feed on (C11-C24 chain length). If you're prone to fungal acne, this one's probably not for you.
You'll also see this ingredient listed as: Macadamia Ternifolia Seed Oil. This is the same ingredient; M. ternifolia is an older INCI naming convention for the edible macadamia nut, while M. integrifolia is the species actually cultivated for oil production. Both names refer to the same oil.
Learn more about Macadamia Integrifolia Seed OilJojoba oil is one of the most well-studied plant-derived ingredients in cosmetics. It is an emollient with a special structure.
Because it is made up of 97-98% wax esters, it closely mirrors the linear monoesters found in human sebum. This makes it skin compatible, non-greasy, and lightweight.
Unlike other plant oils, jojoba wax doesn't easily penetrate skin. It mostly works in the uppermost layers as an emollient. This just means it forms a light barrier on the skin to help retain moisture.
Formulations with jojoba esters up to 90% reduced transepidermal water loss (TEWL) and increased barrier recovery by 81% (outperforming bisabolol at 47%).
Besides barrier support, the science also suggests jojoba to have anti-inflammatory effects and potential applications for skin infections, aging, and wound healing.
Fun fact: Indigenous cultures have used jojoba as a moisturizer and to help treat burns for centuries.
Due to its fatty acid content, Jojoba oil may not be fungal acne safe.
Learn more about Simmondsia Chinensis Seed OilLaminaria Digitata Extract comes from the dark brown seaweed, Laminaria Digitata. It is a potent antioxidant, which also provides soothing and hydrating benefits.
Many studies show the antioxidant components of Laminaria Digitata to help with anti-inflammation.
This ingredient is rich in amino acids, proteins, sugars, and vitamins. Small amounts of minerals such as phosphorous, iron, potassium, and copper are also found the seaweed.
These components help hydrate and nourish your skin's natural barrier. Having a healthy skin barrier leads to more youthful looking skin and may help reduce the signs of aging.
Laminaria Digitata is found in the northern Atlantic Ocean.
What's the difference between algae and seaweed?
Algae is a broad term that includes seaweed. Not all algae is seaweed.
Hydrolyzed rice protein is a plant-derived ingredient with hydrating, antibacterial and anti-aging properties.

It has the following skin benefits:
In hair care, this ingredient can help reduce breakage, enhance shine, and reduce frizz.
Read more about the benefits of rice extract here.
Learn more about Hydrolyzed Rice ExtractCholesterol is a lipid that is naturally found in human skin and is one of the three key components of your skin barrier. In skincare, it is an emollient and barrier-repairing ingredient.
It works by fitting directly into the lipid layers of skin to help restore structure and reduce transepidermal water loss (TEWL).
This is a great ingredient for dry, compromised, or aging skin; our skin starts to produce less cholesterol with age.
Research shows cholesterol works best in combination with ceramides and fatty acids, the other two major components in your skin barrier.
Cholesterol is also a well-establish penetration enhancer and can help other actives absorb more effectively.
Cosmetic-grade cholesterol is usually derived from lanolin but plant and synthetic options also exist. We recommend reaching out to the brand if you have questions about their source of cholesterol.
Learn more about CholesterolThis is a botanical extract from the rosemary plant (the same one you cook with). In skincare, it mostly works as a skin conditioning agent.
Its activity comes from a handful of polyphenols, carnosic acid, carnosol, and rosmarinic acid. Almost 90% of the antioxidant activity of this ingredient can be attributed to canosol and carnosic acid.
These compounds protect your skin two ways:
1) They fight off free radicals, or the unstable molecules from things like sun and pollution that age and damage skin.
2) They help calm inflammation by switching off the chemical signals that tell skin to get red and irritated.
Lab studies also suggest that rosmarinic acid may help protect collagen and slow sugar-related damage to it.
The Cosmetic Ingredient Review has concluded rosemary-derived ingredients to be safe when formulated to be non-sensitizing.
Rosemary can occasionally cause allergic contact dermatitis (due to carnosol), so be sure to patch test if you have reactive or fragrance-sensitive skin.
Learn more about Rosmarinus Officinalis Leaf ExtractAcetyl Glucosamine is an antioxidant and humectant. It is an amino acid sugar and is naturally found in our skin.
The cool thing about this ingredient? It helps the skin produce hyaluronic acid and boost hydration. It also has antioxidant benefits to protect skin cells.
When paired with niacinamide, Acetyl Glucosamine has been shown to be effective at reducing discoloration.
Learn more about Acetyl GlucosamineSorbitol is a sugar alcohol. It is a hydrating and moisturizing agent created from the reduction process of glucose.
Most sorbitol is usually made from potato starch. It is also found in fruits such as apples and pears.
As a humectant, Sorbitol helps draw water to the skin. This helps keep the skin hydrated. Sorbitol also helps create a thicker texture in products. You might find sorbitol in your toothpaste and other gels.
It is a non-irritating ingredient that is great for those with dry skin.
Sorbitol is a prebiotic. It helps promote the growth of healthy bacteria on your skin. The bacteria on your skin form a microbiome. This microbiome helps protect your skin from infection and harmful bacteria.

Dextrin Palmitate comes from the palmitic acid ester of Dextrin. It is used as an emulsifier and texture enhancer.
Emulsifiers help keep ingredients together. According to a manufacturer, dextrin palmitate helps create a low-viscosity gel texture.
Due to its fatty acid base, this ingredient is not fungal-acne safe.
Learn more about Dextrin PalmitateUrea is also called carbamide and is the diamide of carbonic acid. In cosmetics, urea is used to hydrate the skin. It also provides exfoliation in higher concentrations.
As a humectant, urea helps draw moisture from the air and from deep within the skin. This helps hydrate your skin. Studies show urea is an effective moisturizer for dry skin conditions. 40% urea is typical in medications for treating eczema and other skin conditions.
Urea has the strongest exfoliation effect in concentrations higher than 10%. It is a keratolytic agent, meaning it breaks down the keratin protein in the top layer of skin. This helps remove dead skin cells and flaking skin.
In medicine, urea has been shown to help increase the potency of other ingredients, such as fungal treatments.
Humans and animals use urea to metabolize nitrogen-containing compounds. Urea is highly soluble in water. Once dissolved, it is neither acidic nor alkaline.
Urea is actually one of the more well-studied and well-supported ingredients out there if you have eczema.
Clinical trials have shown that urea creams in the 5 - 10% range can:
Higher concentrations (20 -30%) can also help with thickened, scaly patches but is also more likely to sting on active flares.
Skip urea if you have rosacea. The AAD (American Academy of Dermatology) lists it alongside alcohol, menthol, and fragrance as a potential irritant for rosacea-prone skin. Urea's keratolytic and penetration-enhancing properties can trigger stinging, burning, and redness.
As always, your skin is unique, so definitely check in with your dermatologist.
Learn more about UreaAcetyl Hexapeptide-8, commonly known as Argireline or Acetyl Hexapeptide-3, is a popular peptide in skincare. It’s often referred to as a “Botox-like” ingredient because it helps reduce muscle movement.
By relaxing these micro-movements, Argireline may help minimize the appearance of fine lines and wrinkles. That said, it’s not as powerful as Botox, and research on its long-term effectiveness is still limited.
Beyond smoothing, Argireline may also support collagen production. Collagen is the protein that helps keep your skin firm, bouncy, and well-hydrated by strengthening the skin barrier.
So while Argireline isn’t a miracle fix, it can be a helpful addition to a routine focused on both prevention and skin health.

As an antioxidant, caffeine protects your skin from free radical damage caused by UV exposure and envionrmnetal stressors.
Early research also shows that caffeine can help calm redness, soothe irritated skin, and support hair growth by stimulating microcirculation in the scalp.
You might have seen eye creams marketing caffeine as a depuffing ingredient. This is because it is a vasoconstrictor meaning it can temporarily constrict blood vessels, though clinical evidence for this specific use is still limited.
Most skincare products contain this ingredient at concentrations between 1-6%. It is able to penetrate skin easily regardless of skin type or thickness.
Just so you know, a very small number of case reports describe caffeine-induced allergy. This ingredient is generally well-tolerated, non-irritating, and non-sensitizing for the majority of people.

Gold flakes and colloidal/nano gold are often marketed for being skin soothing, anti-aging, and revitalizing.
While lab studies suggest gold nanoparticles may have anti-inflammatory or antioxidant potential, there is limited high-quality human evidence showing clear skin benefits at typical cosmetic use levels.
The EU has raised safety concerns around gold nanomaterials due to insufficient data on skin penetration and long term exposure. Additionally, gold is a known contact allergen. This means it may trigger irritation or allergic reactions in individuals sensitive to gold.
In the EU, gold is listed as CI 77480 and only permitted for use as a cosmetic colorant. The US and FDA does not list it as an approved cosmetic color additive. This affects how products that contain gold are labeled or formulated in the US market.

Typical use levels vary from 0.3-1% as a preservative booster and go up to 2% to condition skin.
Because it is not a free-fatty acid or alcohol, this ingredient is fungal acne safe (there's nothing for Malassezia to feed on).
Learn more about Caprylyl GlycolTocopheryl Acetate is AKA Vitamin E. It is an antioxidant and protects your skin from free radicals. Free radicals damage the skin by breaking down collagen.
One study found using Tocopheryl Acetate with Vitamin C decreased the number of sunburned cells.
Tocopheryl Acetate is commonly found in both skincare and dietary supplements.
Learn more about Tocopheryl AcetateThis ingredient is a lightweight emollient, solvent, and texture enhancer. It is considered a skin-softener by helping the skin prevent moisture loss.
It helps thicken a product's formula and makes it easier to spread by dissolving clumping compounds.
Caprylic Triglyceride is made by combining glycerin with coconut oil, forming a clear liquid. Though it behaves like an oil, it is not technically one due to its chemical composition. It is very stable, resistant to oxidation, and unlikely to go rancid. In practice, that translates to a long shelf life and a consistently elegant skin feel.
While there is an assumption Caprylic Triglyceride can clog pores due to it being derived from coconut oil, there is no research supporting this. Be sure to patch test if you have concerns.
Fractionated coconut oil and MCT Oil are both listed as Caprylic/Capric Triglyceride according to INCI. This is because INCI names are based on the ingredient’s final chemical composition and not its marketing name or source.
Learn more about Caprylic/Capric TriglycerideTrehalose is a disaccharide made of two glucose molecules (glucose is sugar!). Trehalose is used to help moisturize skin. It also has antioxidant properties.
As a humectant, trehalose helps draw moisture from the air to your skin. This helps keep your skin hydrated.
Due to its antioxidant properties, trehalose may help with signs of aging. Antioxidants help fight free-radical molecules, unstable molecules that may damage your skin.
In medicine, trehalose and hyaluronic acid are used to help treat dry eyes.
Some animals, plants, and bacteria create trehalose as a source of energy to survive freeze or lack of water.
Learn more about TrehaloseLactobionic Acid is a PHA. PHAs are the gentle cousins to AHAS.
Like AHAs, they exfoliate the top layer of skin. Lactobionic acid also exhibits significant antioxidant activity.
PHAs are more gentle than AHAs due to their larger structure. This means they do not penetrate as deeply as AHAs and take a longer time to dissolve dead cells. Studies show PHAs do not cause as much irritation.
By removing dead skin cells, PHAs leave the skin brighter and with even-texture.
Learn more about Lactobionic AcidGlycine Soja Sterols is derived from the soybean plant. Sterols are an organic compound and technically an alcohol.
Unlike solvent alcohols, glycine soja sterols have emollient properties and help hydrate the skin.
This ingredient may not be Malassezia folliculitis, or fungal-acne safe.
Sterols can be found in plants, animals, and fungi.
Learn more about Glycine Soja SterolsSodium PCA is the sodium salt of pyroglutamic acid. It is naturally occurring in our skin's natural moisturizing factors where it works to maintain hydration.
The PCA stands for pyrrolidone carboxylic acid, a natural amino acid derivative.
This ingredient has skin conditioning, anti-inflammatory, and humectant properties. Humectants help hydrate your skin by drawing moisture from the air. This helps keep your skin moisturized.
Learn more about Sodium PCAGlucose is a simple sugar (a monosaccharide). In skincare, it is mostly a humectant and skin conditioning agent.
Mechanistically, it has multiple hydroxyl groups that hydrogen-bond to water. This pulls moisture into the upper layers of skin to keep the surface soft and hydrated.
It's worth knowing sugars are already a natural component of the skin's NMF (natural moisturizing factor) so it's a molecule that your stratum corneum is well-acquainted with.
Just so you know, glucose is hydrophilic (water-loving) and the stratum corneum is a strong barrier to hydrophilic compounds. This just means penetration is slow and most of the action is happening on the surface.
Gram-to-gram, glucose is not as efficient as a humectant as glycerin. This is why you'll likely see glycose paired with stronger humectants for a bigger hydration payoff.
In skincare, glucose is typically derived from corn or other starch sources.
Learn more about GlucoseDipotassium Glycyrrhizate comes from licorice root.
Extracts of licorice have demonstrated to have antibacterial, anti‐inflammatory, antiviral, antioxidant properties.
One component, glabridin, has extra potent antioxidant and soothing properties. It has also been found to block pigmentation from UVB rays in guinea pigs.
Licorice Root also contains a flavonoid. Flavonoids are a natural substance from in plants. Flavonoids also have antioxidant properties.
Another component, glycyrrhizin, has been found to have anti-inflammatory and antimicrobial benefits. This may make licorice root extract effective at treating acne. However, more research is needed to support this.
Liquiritin is one of the flavone compounds found in licorice. It has been found to help lighten skin by preventing tyrosinase from reacting with tyrosine. When the two react, protein is converted to melanin. Melanin is the substance in your body that gives your features pigmentation.
Licorice root is native to Southern Europe and Asia. It has been used in traditional Chinese medicine to help with respiratory issues.
Learn more about Dipotassium GlycyrrhizateAminopropyl Ascorbyl Phosphate (AAP) is a form of Vitamin C. AAP was made as a more stable alternative to Ascorbic Acid by combining Ascorbic Acid (pure Vitamin C) with 3-aminoproply dehydrogen phosphate.
As a type of Vitamin C, it has antioxidant properties. Antioxidants help fight free-radical molecules, or molecules that may damage your skin cells.
AAP has been shown to help reduce signs of hyperigmentation and age-spots.
AAP is water soluble.
Vitamin C can help to reduce redness, improve skin texture, reduce the effects of aging, and reduce the visibility of dark spots.

Fatty Alcohols have hydrating properties and are most often used as an emollient or to thicken a product. They are usually derived from natural fats and oils; behenyl alcohol is derived from the fats of vegetable oils.
Emollients help keep your skin soft and hydrated by creating a film that traps moisture in.
In 2000, Behenyl Alcohol was approved by the US as medicine to reduce the duration of cold sores.
Learn more about Behenyl AlcoholCarbomer is a high-molecular weight polymer of acrylic acid. It is used to form gels and thicken formulas.
Due to its large molecular size, carbomer has minimal skin penetration and is considered an inert ingredient.
A high amount of carbomer can cause pilling or balling up of products. Don't worry, most products contain 1% or less of carbomer.
Learn more about CarbomerSodium Hydroxide is also known as lye or caustic soda. It is used to adjust the pH of products; many ingredients require a specific pH to be effective.
In small amounts, sodium hydroxide is considered safe to use. However, large amounts may cause chemical burns due to its high alkaline.
Your skin has a natural pH and acid mantle. This acid mantle helps prevent harmful bacteria from breaking through. The acid mantle also helps keep your skin hydrated.
"Alkaline" refers to a high pH level. A low pH level would be considered acidic.
Learn more about Sodium HydroxideCetyl Alcohol is a fatty alcohol. Fatty Alcohols are most often used as an emollient or to thicken a product.
Its main roles are:
Though it has "alcohol" in the name, it is not related to denatured alcohol or ethyl alcohol.
The FDA allows products labeled "alcohol-free" to have fatty alcohols.
Learn more about Cetyl AlcoholMyristyl Alcohol is type of fatty alcohol. Fatty Alcohols are most often used as an emollient or to thicken a product.
As an emollient, myristyl alcohol hydrates the skin by trapping moisture in.
Fatty alcohols are usually derived from natural fats and oils and therefore do not have the same drying or irritating effect as solvent alcohols.
The FDA allows "alcohol-free" products to contain fatty alcohols.
Learn more about Myristyl AlcoholSodium Hyaluronate is the salt form of hyaluronic acid. It is a long sugar chain that is naturally found in your skin, joints, and connective tissue that maintains hydration and elasticity.
In skincare, it works as a humectant. It pulls water from the environment and deeper layers of skin and binds it to the surface.
Interestingly, the size of the molecule affects its behavior:
Some clinical evidence links low molecular weight versions to improved wrinkle depth, elasticity, anti-inflammatory effects, and barrier repair.
Many serums use a blend of both weights so you can get surface hydration plus longer-lasting and deeper effects.
You'll typically see concentrations between 0.1-2% for this ingredient.
Learn more about Sodium HyaluronatePolyquaternium-51 is a polymer salt. It helps hydrate the skin by creating a film on top. This film traps moisture in, keeping your skin soft and hydrated.
Citric Acid is an alpha hydroxy acid (AHA) naturally found in citrus fruits like oranges, lemons, and limes.
Like other AHAs, citric acid can exfoliate skin by breaking down the bonds that hold dead skin cells together. This helps reveal smoother and brighter skin underneath.
However, this exfoliating effect only happens at high concentrations (20%) which can be hard to find in cosmetic products.
Due to this, citric acid is usually included in small amounts as a pH adjuster. This helps keep products slightly more acidic and compatible with skin's natural pH.
In skincare formulas, citric acid can:
While it can provide some skin benefits, research shows lactic acid and glycolic acid are generally more effective and less irritating exfoliants.
Most citric acid used in skincare today is made by fermenting sugars (usually from molasses). This synthetic version is identical to the natural citrus form but easier to stabilize and use in formulations.

Learn more about Citric AcidPolymethylsilsesquioxane is a silicone used as a film forming agent.
When applied to the skin, this ingredient creates an invisible film on the surface. This film still allows oxygen to pass through, but prevents moisture from escaping. This can help condition and hydrate the skin. It also leaves a silky feel when applied.
Polymethylsilsesquioxane has not been shown to clog pores. It has been deemed safe to use up to 55%, but most cosmetics use much less.
If you have concerns about using this ingredient, we recommend speaking with a professional.
Learn more about PolymethylsilsesquioxaneTriacetin comes from glycerin and acetic acid. It has antimicrobial properties.
Due to its ability to kill off microorganisms, it can help reduce odor caused by bacteria. Hence, it is a masking ingredient.
Sodium Sulfite is a preservative. Preservatives help prevent mold and bacteria from growing in cosmetics.
This ingredient has been shown to break the bonds in hair, acting as a natural straightener.
It is commonly used in food. It should be noted sodium sulfite degrades both vitamins B1 and E.
Fun fact: Sulfites are naturally occuring in wine.
Learn more about Sodium SulfiteSodium metabisulfite is also known as Sodium Pyrosulfite. It is a preservative, antioxidant, and disinfectant.
As a preservative, it helps stabilize cosmetic formulas without affecting their color or scent.
Potassium Phosphate is the term for the salts of potassium and phosphate ions. Our bodies naturally create and use potassium phosphate.
In cosmetics, potassium phosphate is used to adjust the pH level of products. Our skin has a natural pH level. Maintaining this pH level is important for our skin barrier. If the skin barrier is disrupted, our skin can experience dehydration and irritation.
This ingredient is used in medicine to help treat low blood levels of phosphorus.
Learn more about Potassium PhosphateChances are, you eat sodium chloride every day. Sodium Chloride is also known as table salt. This ingredient has many purposes in skincare: thickener, emulsifier, and exfoliator.
You'll most likely find this ingredient in cleansers where it is used to create a gel-like texture. As an emulsifier, it also prevents ingredients from separating.
You might see people debate whether Sodium Chloride is comedogenic, but there actually haven't been any comedogenic tests done on it. Either way, the overall formulation of a product matters a lot more than any single ingredient.
You might see this ingredient used in scrubs as a primary exfoliating ingredient.
Learn more about Sodium ChlorideTocopherol is a fat-soluble antioxidant known as Vitamin E.
You'll find this ingredient in the vast majority of skincare (for good reason). It works to neutralize free radicals, or unstable molecules generated by UV exposure, pollution, and other environmental stressors, before they can cause oxidative damage to your skin cells.
Topically applied tocopherol has been shown to protect against UV damage by ramping up the skin's own natural defense enzymes.
It also acts as a skin conditioning agent; some studies show that regular topical use can improve the skin's water-binding capacity over 2-4 weeks.
This ingredient is especially loved for being a team player. When combined with Vitamin C, the photoprotective effect of both ingredients roughly doubles and the combo also helps reduce UV-induced DNA damage.
This ingredient has some brightening potential but it's more of a prevention ingredient than spot-fader. Cell studies show it can slow down melanin production but it's worth noting that it's not the most powerful brightener out there.
In formulations, it also serves as a stabilizer that helps protect other oxidation-prone ingredients from degrading.
Concentrations usually range from 0.1-1% in most leave-on products.

This ingredient has many functions:
Fun fact: Cellulose is the most abundant form of organic polymer on Earth.
Learn more about CelluloseParfum is a catch-all term for an ingredient or more that is used to give a scent to products.
Also called "fragrance", this ingredient can be a blend of hundreds of chemicals or plant oils. This means every product with "fragrance" or "parfum" in the ingredients list is a different mixture.
For instance, Habanolide is a proprietary trade name for a specific aroma chemical. When used as a fragrance ingredient in cosmetics, most aroma chemicals fall under the broad labeling category of “FRAGRANCE” or “PARFUM” according to EU and US regulations.
The term 'parfum' or 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term.
For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance by INCI standards.
One example is Calendula flower extract. Calendula is an essential oil that still imparts a scent or 'fragrance'.
Depending on the blend, the ingredients in the mixture can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.
Parfum can also be used to mask or cover an unpleasant scent.
The bottom line is: not all fragrances/parfum/ingredients are created equally. If you are worried about fragrances, we recommend taking a closer look at an ingredient. And of course, we always recommend speaking with a professional.
Learn more about ParfumDisodium EDTA is a chelating agent. It grabs onto and deactivates metal ions that sneak into your products from water, packaging, or air.
This ingredient mainly works behind the scenes and helps with:
On top of that, this ingredient can counteract the effects of hard water by binding to the minerals in it.
One thing worth knowing is that Disodium EDTA has been shown to be a mild penetration enhancer. It can help other ingredients absorb into skin more effectively which can be a double-edged sword (great for actives, but can also make the active too strong if you have sensitive skin).
Clinical patch testing showed no significant skin irritation at typical use concentrations and minimal dermal absorption.
You'll most likely see this ingredient near the end of an ingredient list. It's typically found in concentrations less than 1%.
Learn more about Disodium EDTABHT is a synthetic antioxidant and preservative.
As an antioxidant, it helps your body fight off free-radicals. Free-radicals are molecules that may damage your skin cells.
As a preservative, it is used to stabilize products and prevent them from degrading. Specifically, BHT prevents degradation from oxidation.
The concerns related to BHT come from oral studies; this ingredient is currently allowed for use by both the FDA and EU.
However, it was recently restricted for use in the UK as of April 2024.
Learn more about BHTChlorphenesin is a synthetic preservative. It helps protect a product against bacteria in order to extend shelf life. In most cases, Chlorphenesin is paired with other preservatives such as phenoxyethanol and caprylyl glycol.
Chlorphenesin is a biocide. This means it is able to help fight the microorganisms on our skin. It is also able to fight odor-releasing bacteria.
Chlorphenesin is soluble in both water and glycerin.
Studies show Chlorphenesin is easily absorbed by our skin. You should speak with a skincare professional if you have concerns about using Chlorphenesin.
Learn more about ChlorphenesinPotassium Sorbate is a preservative used to prevent yeast and mold in products. It is commonly found in both cosmetic and food products.
This ingredient comes from potassium salt derived from sorbic acid. Sorbic acid is a natural antibiotic and effective against fungus.
Both potassium sorbate and sorbic acid can be found in baked goods, cheeses, dried meats, dried fruit, ice cream, pickles, wine, yogurt, and more.
You'll often find this ingredient used with other preservatives.
Learn more about Potassium SorbateSorbic Acid is a preservative. It is the most commonly used food preservative in the world.
Sorbic Acid is a natural antibiotic and highly effective at preventing the growth of fungus. It is less effective against bacteria.
Potassium Sorbate, another commonly-used preservative, is the potassium salt of Sorbic Acid.
Sorbic Acid may worsen eczema. We recommend speaking with a professional if you have any concerns.
Potassium sorbate and sorbic acid can be found in baked goods, cheeses, dried meats, dried fruit, ice cream, pickles, wine, yogurt, and more.
Learn more about Sorbic AcidSodium Benzoate is a preservative. It's used in both cosmetic and food products to inhibit the growth of mold and bacteria. It is typically produced synthetically.
Both the US FDA and EU Health Committee have approved the use of sodium benzoate. In the US, levels of 0.1% (of the total product) are allowed.
Sodium benzoate works as a preservative by inhibiting the growth of bacteria inside of cells. It prevents the cell from fermenting a type of sugar using an enzyme called phosphofructokinase.
It is the salt of benzoic acid. Foods containing sodium benzoate include soda, salad dressings, condiments, fruit juices, wines, and snack foods.
Studies for using ascorbic acid and sodium benzoate in cosmetics are lacking, especially in skincare routines with multiple steps.
We always recommend speaking with a professional, such as a dermatologist, if you have any concerns.
Learn more about Sodium BenzoatePhenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent microbial growth. By itself, it has a scent that is similar to that of a rose.
It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
CI 19140 is also known as Tartrazine. Tartrazine is a synthetic dye used in cosmetics, foods, and medicine to add a yellow color.
Tartrazine is created from petroleum and is water-soluble.
Some people may experience allergies from this dye, especially asthmatics and those with an aspirin intolerance.
Learn more about CI 19140CI 17200 is a synthetic, water-soluble, reddish-pink dye. It is used purely as a cosmetic colorant.
In the US, the FDA permits this ingredient in cosmetics but it is not approved for use around the eyes while the EU allows this to be used in all cosmetic products.
The FDA requires batch-to-batch certification for this ingredient that is held to a pretty rigorous standard. That means the CI 17200 in your cosmetics has been tested and approved before it ever reaches you.
Contact allergy to cosmetic-grade dyes used at low concentrations are uncommon but has been documented before.
This ingredient also goes by the name D&C RED NO. 33.
CI 17200 has a comedogenic rating of 1 and an irritancy rating of 2 on a scale of 0-5. This is based on peer-reviewed research from the man who invented the comedogenic scale.
A 1 on the comedogenic scale is about as low as it gets without being a flat zero, and makes sense for CI 17200.
It's a water-soluble dye used at very small concentrations (typically 0.001-0.1%), so it dissolves into the water phase of a formula rather than sitting on your skin the way an oil or wax would.
The irritancy rating of 2 reflects that, like most synthetic dyes, there's a small possibility of mild irritation ( particularly for people with existing dye sensitivities).
For the vast majority of people, it's a non-issue at typical use levels.
It's also worth keeping in mind that comedogenic and irritancy ratings are tested on individual ingredients, not finished formulas. The final product's formulation, concentration, and other ingredients all play a role in how something actually behaves on your skin.
Just so you know, the FDA ban on Red Dye No. 3 refers to CI 45430, not this ingredient. CI 45430 and CI 17200 are different chemical compounds with distinct safety and regulatory histories.
It's also worth noting that Red No. 3 (CI 45430) was already banned from cosmetics back in 1990, so the 2025 action just extended the ban to food and oral drugs. CI 17200 was never part of any of this.
