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 WaterPropanediol 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 PropanediolCoco-Caprylate/Caprate is created from fatty coconut alcohol, caprylic acid, and capric acid.
It is a lightweight emollient. Emollients create a thin barrier on the skin to trap moisture in. This helps keep your skin hydrated and soft.
Once applied, Coco-Caprylate/Caprate is absorbed quickly and leaves a silky feel.
Coco-Caprylate/Caprate may not be fungal acne safe.
Learn more about Coco-Caprylate/CaprateBetaine is a humectant. Like hyaluronic acid, it helps attract and retain moisture in the skin. It’s known for being gentle and for helping the skin maintain balanced hydration.
Betaine is mainly used to improve hydration and support calmer skin. It helps skin cells regulate water balance because it functions as an osmolyte.
Some studies suggest betaine may support making skin tone more even.
Fun fact: Betaine naturally exists in the skin and the body. In cosmetic products, it can be either plant-derived (most commonly from sugar beets) or synthetically produced for consistency and stability.
Betaine is also known as trimethylglycine.
Learn more about BetaineThis 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 TriglyceridePentylene glycol is typically used within a product to thicken it. It also adds a smooth, soft, and moisturizing feel to the product. It is naturally found in plants such as sugar beets.
The hydrophilic trait of Pentylene Glycol makes it a humectant. As a humectant, Pentylene Glycol helps draw moisture from the air to your skin. This can help keep your skin hydrated.
This property also makes Pentylene Glycol a great texture enhancer. It can also help thicken or stabilize a product.
Pentylene Glycol also acts as a mild preservative and helps to keep a product microbe-free.
Some people may experience mild eye and skin irritation from Pentylene Glycol. We always recommend speaking with a professional about using this ingredient in your routine.
Pentylene Glycol has a low molecular weight and is part of the 1,2-glycol family.

Limnanthes 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 OilVitis 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 OilCarthamus tinctorius seed oil comes from safflower, one of humanity's oldest crops.
Safflower seed oil contains a high percentage of linoleic acid and oleic acid. It also contains Vitamin E. These three components are effective moisturizers.
Vitamin E helps nourish your skin's lipid barrier. It is also a potent antioxidant. Antioxidants help fight free-radical molecules, or unstable molecules that may damage your skin cells.
Due to its high fatty acid content, this ingredient may not be malassezia folliculitis safe.
Thoughout history, safflower has been used for dying fabrics and in food as a saffron substitute.
Learn more about Carthamus Tinctorius Seed 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 OilHydrolyzed pea protein has skin conditioning and emollient properties. It is created by cutting protein fragments (peptides) into smaller pieces.
According to a manufacturer, this size of this ingredient makes it easy to be absorbed into skin where they strengthen the skin barrier, improve moisture retention, and improve signs of irritation.
One study that included pea proteins in a topical product reported improved atopic dermatitis symptom scores while a patent containing this ingredient suggests this ingredient to support hydration-related pathways in the skin.
Learn more about Hydrolyzed Pea ProteinWe don't have a description for Hydrolyzed Vegetable Protein yet.
Hippophae Rhamnoides Oil also known as seabuckthorn oil. This oil is usually extracted from the fruit pulp or seeds.
Seabuckthorn is rich in phytosterols, carotenoids, Vitamins A, C, and E. This gives it strong antioxidant properties that can help soothe and protect your skin from oxidative damage.
This oil is rich in fatty acids, including: two types of linoleic acid (~30-34%), oleic acid (17%), and palmiteic acid (35%). Note these numbers are averages, and different parts of the plant will vary.
Palmitoleic acid has been shown to help soothe inflammation and promote wound healing. It is also naturally found in the fat of our skin.
Overall, seabuckthorn oil is great for nourishing, hydrating, and soothing skin. While it shows UV protecting properties, it should not replace sunscreen.
Due to the rich fatty acid content, this ingredient may not be Malassezia folliculitis, or fungal acne, safe.
Seabuckthorn berries are little orange fruits. This plant is native to Asia.
Learn more about Hippophae Rhamnoides OilOenothera 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.
Learn more about Oenothera Biennis OilRosehip Oil is a non-fragrant plant oil. Rosehips are a fruit from a rose bush and are edible. This oil has skin conditioning and hydrating properties.
Rosehip contains Vitamin C, Vitamin E, fatty acids and linolenic acids. These nourish your skin barrier. Having hydrated skin may help reduce the appearance of fine-lines and wrinkles.
Another great component of Rosehip Oil is Vitamin A, or retinol. Vitamin A encourages your skin to create more collagen.
Rosehip oil may help with reducing pigmentation. The lycopene and beta-carotene have skin-lightening properties. However, more studies are needed to confirm this.
Learn more about Rosa Canina Fruit OilTocopherol 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.
Learn more about TocopherolCalendula Officinalis Flower Extract comes from the common Marigold plant part of the Asteraceae family. This ingredient is a skin conditioner.
Marigolds contain flavonoids. Flavonoids are a group of substances found naturally in plants. They possess antioxidant and inflammation properties.
This ingredient soothes skin inflammation by inhibiting inhibiting a part of the inflammation process.
Marigolds have been used in traditional medicine throughout Asia and Europe.

Daucus Carota Sativa Root Extract comes from the root commonly known as carrot (the orange kind we eat!).
This extract contains beta-carotene, a pigment responsible for giving plants the orange color. Beta-carotene is a potent antioxidant. Antioxidants may help reduce the signs of aging.
Beta-carotene is the reason we turn orange if we eat too many carrots.
It should be noted coming into contact with the leaves of wild carrots can cause skin irritation. The sap causes phytophotodermatitis, or sensitivity exposed to sunlight.
This ingredient is created using the edible parts of the carrot.
Learn more about Daucus Carota Sativa Root ExtractCitrus Aurantium Bergamia Fruit Extract comes from the bergamot orange.
Bergamot oranges contain antioxidants, dietary fiber, vitamins such as Vitamin C, and minerals.
Parfum 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 ParfumCastor Oil/Ipdi Copolymer is an oil and isn't fungal acne safe.
Maltodextrin is a polysaccharide. It is derived from starch such as rice, corn, wheat, or potato starch.
In food, Maltodextrin is used to improve the texture and thicken a product. Due to its structure, it can help create a gel texture. As an emulsion stabilizer, it helps keep the ingredients in a product together.
As a polysaccharide, Maltodextrin has moisturizing properties. Polysaccharides are a type of carbohydrate. The top layer of skin uses polysaccharides to retain water, keeping the skin hydrated.

As an emulsifier, it helps stabilize oil-in-water emulsions to give products an elegant feel when applied.
It can also form a thin protective film on skin. One study found that a formula using this polymer helped slow down how quickly other ingredients (like DEET) were absorbed through skin.
A 2024 study of over 1,300 patients confirmed that sensitization to this ingredient is rare. It is also non-mutagenic and has a clean track record.
Learn more about Acrylates/C10-30 Alkyl Acrylate CrosspolymerChlorphenesin 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 ChlorphenesinCarbomer 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 HydroxideTrisodium Ethylenediamine Disuccinate is used to help stabilize a product.
It is a chelating agent, meaning it helps prevent metal ions from binding to other ingredients. This prevents unwanted reactions in products. Metal ions can come into a product via the water ingredient. They are found in trace amounts and are not known to be harmful.
Acacia Senegal Gum has skin soothing, thickening, and formulation stabilizing properties. It comes from the Acacia tree that is native to sub-Saharan Africa.
Xanthan gum is used as a stabilizer and thickener within cosmetic products. It helps give products a sticky, thick feeling - preventing them from being too runny.
On the technical side of things, xanthan gum is a polysaccharide - a combination consisting of multiple sugar molecules bonded together.
Xanthan gum is a pretty common and great ingredient. It is a natural, non-toxic, non-irritating ingredient that is also commonly used in food products.
Learn more about Xanthan GumTamarindus Indica Seed Gum is from the seeds of Tamarindus indica. It is more commonly known as tamarind.

Learn more about Tamarindus Indica Seed GumPotassium 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 SorbateSodium 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 BenzoateGlucose 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 GlucoseCi 77491 is also hydrated iron III oxide. It's sole purpose is to give an orange hue to products.
Iron III oxides are classified as inorganic chemicals for coloring.
Synthetically created Ci 77491 is considered safer than those naturally found. This is because the synthetically created version may contain less impurities. Iron oxides are generally non-toxic and non-allergenic.
Learn more about CI 40800Limonene is a fragrance that adds scent and taste to a formulation.
It's found in the peel oil of citrus fruits and other plants such as lavender and eucalyptus. The scent of limonene is generally described as "sweet citrus".
Limonene acts as an antioxidant, meaning it helps neutralize free radicals.
When exposed to air, oxidized limonene may sensitize the skin. Because of this, limonene is often avoided by people with sensitive skin.
The term '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.
Learn more about LimoneneLinalool is a fragrance and helps add scent to products. It's derived from common plants such as cinnamon, mint, citrus, and lavender.
Like Limonene, this ingredient oxidizes when exposed to air. Oxidized linalool can cause allergies and skin sensitivity.
This ingredient has a scent that is floral, spicy tropical, and citrus-like.
Learn more about LinaloolHexyl Cinnamal is a fragrance ingredient with a similar scent to jasmine. It can be naturally found in chamomile essential oil.
This ingredient is a known EU allergen and may sensitize the skin. The EU requires this ingredient to be listed separately on an ingredients list.
Hexyl Cinnamal is not water soluble but is soluble in oils.
Learn more about Hexyl CinnamalCoumarins are a group of substances found naturally in plants. There are over 1300 types of coumarins identified. It has a natural vanilla scent.
Coumarin is an identified EU known allergy, meaning it may cause an allergic reaction when applied to the skin.
In many countries, coumarin is banned as a food additive. However, it can be found in soaps, tobacco products, and some alcohol drinks.
