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 WaterGlycerin (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 GlycerinDipropylene Glycol is a synthetically created humectant, stabilizer, and solvent.
This ingredient helps:
Dipropylene glycol is technically an alcohol, but it belongs to the glycol family (often considered part of the โgoodโ alcohols). This means it is hydrating and gentle on skin unlike drying solvent alcohols like denatured alcohol.
As a masking agent, Dipropylene Glycol can be used to cover the smell of other ingredients. However, it does not have a scent.
Studies show Dipropylene Glycol is considered safe to use in skincare.
Learn more about Dipropylene GlycolDimethyl Sulfone is an organic compound that naturally contains sulfur. It is used as a solvent due to its stability. Solvents help mix and stabilize other ingredients.
Studies show taking Dimethyl Sulfone (also known as methylsulfonylmethane or MSM) orally may help reduce the depth of wrinkles. We recommend speaking with a professional if you have any questions or concerns about this ingredient.
Propanediol is an all-star ingredient. It softens, hydrates, and smooths the skin.ย
Itโs 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 PropanediolPanthenol is a common ingredient that helps hydrate and soothe the skin. It is found naturally in our skin and hair.
There are two forms of panthenol: D and L.
D-panthenol is also known as dexpanthenol. Most cosmetics use dexpanthenol or a mixture of D and L-panthenol.
Panthenol is famous due to its ability to go deeper into the skin's layers. Using this ingredient has numerous pros (and no cons):
Like hyaluronic acid, panthenol is a humectant. Humectants are able to bind and hold large amounts of water to keep skin hydrated.
This ingredient works well for wound healing. It works by increasing tissue in the wound and helps close open wounds.
Once oxidized, panthenol converts to pantothenic acid. Panthothenic acid is found in all living cells.
This ingredient is also referred to as pro-vitamin B5.
Learn more about PanthenolHamamelis Virginiana Water is made by distilling parts of the witch hazel plant. You can also call this ingredient "witch hazel water".
The name 'Hamamelis Virginiana Water' refers to the distillation product used in cosmetics. On the other hand, 'Witch Hazel' refers to the active drug ingredient.
Unless it is specified to be non-alcohol, many types of witch hazel ingredients are distilled in denatured alcohol.
Witch Hazel water is an astringent, anti-inflammatory antioxidant, and antibacterial ingredient.
It contains tannins. Tannins have a drying effect when used on skin by constricting proteins. The constriction also minimizes the appearance of pores.
Both the tannins and fragrance found in witch hazel may be skin-sensitizing.
Witch hazel water gets anti-inflammatory and antibacterial properties from its catechin and gallic acid content.
Indigenous groups have used witch hazel to help treat inflammation in North America for centuries.
Learn more about Hamamelis Virginiana WaterGluconolactone is a PHA. PHAs are a great gentle alternative to traditional AHAs.
When applied, Gluconolactone has the same affect on skin as AHAs such as lactic acid. It helps dissolve the dead skin cells in the top layer of your skin. This improves texture and brightens the skin.
PHAs are more gentle than AHAs due to their larger structure. 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.
Gluconolactone has some interesting properties:
In a 2004 study, Gluconolactone was found to prevent UV damage in mouse skin cells and has not been found to increase sun sensitivity. However, we still recommend wearing SPF daily.
This ingredient is is an created by reacting gluconic acid with an alcohol.
Learn more about GluconolactoneAmmonium Polyacryloyldimethyl Taurate is a polymer made from ammonium salts. It works as a thickener, emulsifier, and texture enhancer that gives gel-creams a silky, lightweight feel.
This ingredient is versatile and low-maintenance so manufacturers love working with it.
Typical usage levels in cosmetics are usually low and in the range of 0.015 - 2.3%.
Learn more about Ammonium Polyacryloyldimethyl TaurateSage leaf extract is a culinary and medicinal herb with antibacterial, antioxidant, and soothing properties.
This ingredient is made up of 75-90% ursolic acid, a potent antioxidant and anti-inflammatory compound.
Butylene 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 GlycolPolyglyceryl-10 Laurate is a cleansing agent and emulsifier.
It rounds up dirt, oil, and grime, so they can be rinsed off easily as a cleanser.
On the emulsifier side, it keeps your formula smooth and well-mixed by playing peacekeeper for ingredients that don't naturally get along (like oil and water).
Because it has a C12 (lauric acid) fatty acid chain, this ingredient can potentially feed the Malassezia yeast that causes fungal acne. The Malassezia yeast prefers esters with C11-C24 fatty acids.
This ingredient is an ester of lauric acid and Polyglycerin-10.
Learn more about Polyglyceryl-10 LaurateArctium Majus Root Extract is from the roots of the burdock plant. It is an antioxidant and helps soothe skin.
Juniperus Communis Fruit Extract is a fragrance.
Lemon balm is a mint-family herb with skin conditioning properties. It contains components such as rosmarinic acid, caffeic acid, geraniol, citronellal, and ursolic acid.
Mentha Piperita Leaf Extract is extract from peppermint leaves. It has a "cooling" sensory feel depending on what compounds are found in the extract.
Peppermint leaves contain polyphenols that antioxidant activity. In-vitro studies show anti-inflammatory and antimicrobial activity against some bacteria and fungi.
Evidence for mint as a "treatment" ingredient is limited and depends heavily on the specific extract type and concentration.
In large percentages, peppermint extract may sensitize the skin.
Learn more about Mentha Piperita Leaf ExtractCaprylyl Glycol is a humectant, skin conditioner, emollient, and preservative booster derived from either caprylic acid or synthetically created.
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, this ingredient is fungal acne safe (there's nothing for Malassezia to feed on).

Allantoin is a soothing ingredient known for its protective and moisturizing properties; it's basically a quiet workhorse ingredient you can find in a huge range of cosmetics.
Though it can be derived from the comfrey plant, allantoin is produced synthetically for cosmetic products to ensure purity.
Research shows it can encourage your skin cells to turn over and renew by stimulating keratinocyte and fibroblast proliferation.
It also has mild keratolytic properties to help loosen and shed dead skin cells without being harsh.
Studies also suggest allantoin can help calm inflammation by dialing down some of the chemical signals your skin sends out when it is irritated.
This ingredient is typically used in the 0.1-0.5% range, and the FDA recognizes it as a skin protectant in OTC products up to 2%.
Overall, allantoin is a wonderful addition to most routines; it is stable across a wide pH range (~4-8), works well with other ingredients, and is considered non-sensitizing/non-irritating.
Fun fact: Allantoin is naturally occurring in comfrey root, beets, chamomile, and wheat sprouts. Our bodies even produce it as a byproduct of uric acid metabolism.
Learn more about AllantoinWe don't have a description for Diethoxyethyl Succinate yet.
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 GumDipotassium Glycyrrhizate comes from licorice root.
Extracts of licorice have demonstrated to have antibacterial, antiโinflammatory, 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 GlycyrrhizateEthylhexylglycerin is created from glycerin. It is a multitasker ingredient that:
The CIR Expert Panel found minimal skin absorption or sensitization of any kind in a safety assessment. Though this ingredient is considered well-tolerated, a small number of cases of allergic dermatitis have been published since 2002. Just be sure to patch test if you are unsure.
Industry-reported use ranges from 8% in rinse-off products and 2% in leave-on formulations.
Learn more about Ethylhexylglycerin1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse.ย
It is a:
- Humectant, drawing moisture into the skin
- Emollient, helping to soften skin
- Solvent, dispersing and stabilizing formulas
- Preservative booster, enhancing the antimicrobial activity of other preservativesย
Disodium 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 EDTAGlyceryl Acrylate/Acrylic Acid Copolymer is made up of glycerin and polyacrylic acid. It helps hydrate your skin as a humectant.
This ingredient forms a hydrogel that delivers moisturizing, water-based ingredients to the skin. It is also used to thicken a product and to give it a smooth texture.
Acrylic acid itself is toxic, but the polymer form (this ingredient) is too large to penetrate skin, making it non-toxic.
Learn more about Glyceryl Acrylate/Acrylic Acid CopolymerPVM/MA Copolymer is a synthetic and high-molecular weight polymer. It is used to create a flexible film that helps ingredients "stick together" on hair or skin. It also helps reduce static, help emulsions behave, and tweaks the thickness and flow of a product.
You'll most likely find this ingredient in hair styling products because that film is what helps styles last.

This ingredient is more commonly known as the coffee bean from the Coffea Arabica tree. Besides being a delicious drink, coffee beans have a ton of skin benefits.
Coffea Arabica Seed Extract (CASE) has antioxidant, anti-inflammatory, and UV-protective properties. (It should not replace your sunscreen!)
CASE contains several ingredients that protect and soothe skin. These include caffeine, polysaccharides, sucrose, lipids, minerals, and proteins.
The star ingredient in coffee is caffeine.
Caffeine helps with anti-aging, antioxidant, and photo-protection.
How? It has been shown to block collagenase (~41%), elastase (~35%), and tyrosinase (~13%).
Collagenase and elastase are enzymes that break down collagen and elastin, respectively. Tyrosinase is the enzyme that controls melanin production.
Our skin creates melanin when exposed to UV as a defense mechanism.
It should be noted most studies looked at caffeine's ability to inhibit damage from UV-B rays.
According to a manufacturer, this ingredient is often dissolved using water, glycerin, and propanediol. The caffeine content of this ingredient is about 100 ppm.
Coffea Arabica is native to Ethiopia.
Learn more about Coffea Arabica Seed ExtractCentella Asiatica Leaf Extract comes from the leaves of an herb plant native to Southeast Asia. Centella Asiatica is rich in antioxidants and amino acids. It can help reduce irritation and soothe the skin.
Many active components found in centella asiatica, such as Madecassic Acid and Asiaticoside, encourage the skin to naturally produce hyaluronic acid. This helps keep our skin hydrated. Many of these components also show antioxidant activity and may help reduce the signs of aging.
Research shows centella asiatica can help increase Type I collagen production by increasing fibroblast production. Fibroblast helps form connective tissue.
The combination of all these properties makes centella asiatica leaf extract effective at soothing the skin.
Other components of centella asiatica leaf extract include Vitamin A, vitamin C, several B vitamins, and Asiatic Acid.
Recent studies found madecassoside may help prevent damage from UV rays by preventing UV-induced inflammation. Further research is needed.
This plant has been used as a medicine and in food for many centuries. As a medicine, it is used to treat burns, scratches, and wounds.
Learn more about Centella Asiatica Leaf ExtractDiospyros Kaki Leaf Extract comes from the leaves of the Persimmon. It is native to China, India, and Korea. Persimmon leaves have anti-inflammatory and antioxidant properties.
The leaves of the persimmon tree contain triterpenoids, tannins, and ursolic acids. These components are help sooth the skin due to their antioxidant activity.
Castanea Crenata Shell Extract comes from the shell of the chestnut.
Studies show chestnut shells to have antioxidant and anti-inflammatory properties.
Antioxidants protect your skin against damaging molecules. This may help reduce the signs of aging.
Learn more about Castanea Crenata Shell ExtractGlycine is the smallest amino acid and a key building block of collagen. It's part if your skin's Natural Moisturizing Factor (NMF), or the water-loving molecules in your outermost layer of skin (stratum corneum) that keeps everything hydrated and happy.
A study from 2022 found that an amino acid complex featuring taurine, arginine, and glycine significantly reduced skin irritation, improved redness, and accelerated the skin repair process.
Serine is a non-essential amino acid (your body makes it on its own!). It is a major player in your skin's natural moisturizing factor (NMF), or the water-loving molecules in your outermost layer of skin (stratum corneum) that keeps everything hydrated and happy.
Serine is one of your NMF's most abundant components that works as a skin-identical humectant. Its hydroxyl group grabs onto water molecules to boost hydration without any heaviness or occlusion.
Research on a hydrogel with serine confirmed this serine got delivered to your stratum corneum and demonstrated enhanced skin moisturization.
Interestingly serine also helps your skin produce filaggrin, a protein that keeps your skin barrier strong and used to create collagen.
Learn more about SerineArginine is a semi-essential amino acid. This just means our bodies can product a bit on its own, but sometimes needs a little boost from food sources.
It is a part of your skin's natural moisturizing factor (NMF), or the water-loving molecules in your outermost layer of skin (stratum corneum) that keeps everything hydrated and happy.
Here's an interesting thing about Arginine: your skin converts it into urea through the Krebs-Henseleit urea cycle. Urea is one of the most effective humectants your skin naturally produces.
A clinical study showed applying 2.5% arginine hydrochloride to atopic dermatitis skin showed significant urea levels in the stratum corneum and improved moisture in just four weeks.
Arginine is also a precursor to nitric oxide; nitric oxide improves microcirculation and supports wound healing and collagen synthesis.
One study found that an amino acid complex containing Arginine reduced skin irritation, improved hydration, and accelerated skin repair in clinical / in-vivo studies.
Arginine itself is an amino acid and not a fatty acid, oil, or ester. On its own, it's not a direct food source for Malassezia, or the yeast that causes fungal acne.
Learn more about ArginineAspartic Acid is an amino acid that our bodies produce naturally. It is an antioxidant.
Our body uses Aspartic Acid to help build collagen and elastin. It also plays a role in hydrating skin.
Carthamus Tinctorius extract comes from safflowers.
Glutamic Acid is an amino acid that is found in all living organisms. Our bodies use this to help nerve cells in the brain communicate with other cells.
In cosmetics, glutamic acid is a famous humectant. It draws water from the air to your skin, keeping your skin hydrated (like hyaluronic acid).
An in-vitro study from 2024 found glutamic acid to play a role in inhibiting inflammation and thus a potential skin-soothing ingredient.
Other studies show it to be have potential wound healing, skin barrier repair, and hair growth properties.
Glutamic acid has poor solubility in water and other solvents.
Learn more about Glutamic AcidWe don't have a description for Leucine yet.
Alanine is an amino acid and is already found in the human body. Our skin uses alanine to build collagen, elastin, and keratin.
Lysine is an essential amino acid (your body cannot make it on its own). It has skin conditioning properties and one of the key players in collagen synthesis.
When your body creates collagen, lysine is basically the glue that holds everything together. It helps collagen fibers lock into each other and stay strong, with vitamin C being its trusty sidekick. Without enough lysine, this glue gets flimsy and less firm, resulting in less bouncy skin.
In skincare, lysine is mostly there to help keep your skin moisturized. It carries water through your skin's layers so everything stays plump.
So will putting lysine on your face create bouncier skin?
It's hard to say; most of the exciting collagen research on lysine comes from oral supplements or lab studies on mice. Further research is needed to truly understand what role topical lysine plays in skincare and your skin.
However, there's no harm in adding lysine to your routine as a supportive and hydrating ingredient.
Learn more about LysineProline is a non-essential amino acid, meaning your body can make it on its own. In skincare, it is a skin conditioning ingredient that keeps skin soft and hydrated.
It makes up about 23% of the collagen molecule (collagen is the protein responsible for keeping your skin firm) and is involved in your skin's natural hyaluronic acid production. When applied topically, proline can penetrate the skin fairly well due to its small molecular size.
Reviews of this ingredient have found it to be neither a dermal irritant nor a sensitizer.
Fun fact: Proline can be found in protein-rich foods like meat, fish, eggs, and dairy.
Learn more about ProlinePhenylalanine is an amino acid. It is a skin soothing and hydrating ingredient. Amino acids play a crucial role in wound healing and skin hydration.
This ingredient is also used to help even out skin tone due to its ability to disrupt the melanin production process.
Two structures of phenylalanine exist: L-phenylalanine and D-phenylalanine. L-phenylalanine is essential, this means our bodies cannot produce it naturally and we must get it from foods. Our bodies convert D-phenylalanine to neurotransmitters, and D-phenylalanine is found in our bodies naturally.
Some foods that contain L-phenylalanine include eggs, soybeans, beef, milk.
Learn more about PhenylalanineThreonine is an amino-acid. It helps hydrate the skin and has antioxidant benefits.
Our skin uses threonine for creating collagen and elastin. Humans are not able to create threonine and must get it through eating foods such as fish, lentils, poultry, sesame seeds, and more.
Valine is an essential amino acid. It is used by our bodies for tissue repair and muscle growth.
An essential amino acid is one in which our bodies cannot naturally produce so we must get them through diet. Foods such as eggs, dairy, red meat, and fish contain valine.
This ingredient can either be derived from an animal product or be synthetically created.
Learn more about ValineIsoleucine is an amino acid that helps reinforce our skin barrier. This amino acid plays a role in creating protein for the body.
Fun fact: Isoleucine is found in meat, fish, dairy, legumes, and nuts.
Tyrosine is one of the amino acids used to create protein. It plays a role in melanin production.
A study from 2012 found tyrosine to show promising results in restoring skin volume.
Histidine is a semi-essential amino acid used by our bodies to create protein. It has humectant and skin conditioning properties.
Our bodies use histidine to create filaggrin - filaggrin is a structural protein that the skin uses in maintaining skin barrier.
One study found histidine and carnosine to be a dynamic duo for your skin:
Oral histidine has also been found to help with filaggrin-deficit skin disorders such as atopic dermatitis.
Why is it considered a semi-essential amino acid? This is because adults are able to create it but children must get it from their diet.
Learn more about HistidineCysteine is an amino acid found in our bodies. It becomes an antioxidant when converted into gluthatione.
Once it becomes gluthatione, it prevents oxidative damage to parts of our cell. Gluthatione has also been shown to protect our skin from UV-B induced damage.
Methionine is an essential amino acid. It is a conditioning agent and commonly found in both skin and hair products.
This amino acid is a precursor to glutathione, a powerful antioxidant.
Fun fact: Methionine can be found in meat, fish, and dairy. It cannot be naturally produce and requires dietary intake.
