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. Stay hydrated!
Learn more about WaterSodium Laureth Sulfate (SLES) is a foaming, cleansing, and emulsifying ingredient. It is created from palm kernel oil or coconut oil. SLES is not the same as sodium lauryl sulfate. It is much milder and less likely to irritate.
SLES helps create foam in personal products. It also prevents ingredients from separating, helping to elongate the shelf life.
Sodium Laureth Sulfate is a type of sulfate. It can be drying. We recommend speaking with a professional about using this ingredient if you have concerns.
Learn more about Sodium Laureth SulfateGlycerin is already naturally found in your skin. It helps moisturize and protect your skin.
A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.
As a humectant, it helps the skin stay hydrated by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin.
Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.
Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.
In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.
This ingredient is organic, colorless, odorless, and non-toxic.
Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.
Learn more about GlycerinCocamidopropyl Betaine is a fatty acid created by mixing similar compounds in coconut oil and dimethylaminopropylamine, a compound with two amino groups.
This ingredient is a surfactant and cleanser. It helps gather the dirt, pollutants, and other impurities in your skin to be washed away. It also helps thicken a product and make the texture more creamy.
Being created from coconut oil means Cocamidopropyl Betaine is hydrating for the skin.
While Cocamidopropyl Betaine was believed to be an allergen, a study from 2012 disproved this. It found two compounds in unpure Cocamidopropyl Betaine to be the irritants: aminoamide and 3-dimethylaminopropylamine. High-grade and pure Cocamidopropyl Betaine did not induce allergic reactions during this study.
Learn more about Cocamidopropyl BetaineSodium Lauroyl Sarcosinate is a cleansing agent and emulsifier. It is a surfactant derived from sarcosine, and a common source is coconut oil. As a surfactant, Sodium Lauroyl Sarcosinate helps lift dirts, oil, and other molecules to be washed away. In leave-on products, this ingredient is used as an emulsifier. Emulsifier help prevent ingredients such as oils and waters from separating.
Sodium Lauroyl Sarcosinate is also commonly found as a foaming agent in shampoo, toothpaste, and shaving foam. It is amphiphilic, meaning it loves both water and fats.
Sodium Cocoyl Glutamate is a gentle cleanser and surfactant. It is the sodium salt of the Cocoyl Glutamic Acid and comes from coconut oil. As a surfactant, it helps lift dirt and oil to be washed away.
Sodium Cocoyl Glutamate also has an emolliating effect and can help leave the skin feeling soft.
We don't have a description for Disodium Cocoyl Glutamate yet.
Citric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).
As an AHA, Citric Acid removes the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and even out skin tone.
If you spot Citric Acid near the end of an ingredient list, it's likely there as a pH adjuster rather than an active ingredient.

Learn more about Citric AcidGlycol Distearate serves as a pearlizing or opacifying agent in cosmetic products.
It's often included in cleansers and haircare products to give them a lustrous or shimmering appearance.
It is derived from stearic acid, a natural fatty acid commonly found in vegetable oils and animal fats.
Glycol Distearate isn't fungal acne safe.
Learn more about Glycol DistearateSodium 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 BenzoateThis ingredient is derived from guar gum.
It is a conditioning ingredient, meaning it helps soften skin and hair.
Oryza Sativa Seed Protein is an antioxidant.

Potassium 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 SorbateChances 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.
There is much debate on whether this ingredient is comedogenic. The short answer - comedogenic ratings don't tell the whole story. Learn more about comegodenic ratings here.
The concensus about this ingredient causing acne seems to be divided. Research is needed to understand if this ingredient does cause acne.
Scrubs may use salt as the primary exfoliating ingredient.
Learn more about Sodium ChlorideCottonseed Oil Glycereth-8 Esters is an oil.
Phytic Acid is a gentle AHA and antioxidant. AHAs are chemical exfoliants that help remove dead skin cells. Phytic Acid has a slight and mild exfoliating effect.
The chemical makeup makes it classified as an AHA, much like lactic acid.
In some cases, it is a chelating agent. Chelating agents help prevent metals from binding to water, helping to stabilize the ingredients in a product.
An interesting fact about phytic acid is that it is considered an antinutrient. People do not have the enzyme needed to properly breakdown and digest phytic acid. When ingested, phytic acid binds to minerals and prevents them from being absorbed.

Learn more about Phytic AcidOryza Sativa Extract comes from the rice grain, Oryza sativa. Rice extract has wound healing, antioxidant, anti-inflammatory, and hydrating properties.
Rice grains contain numerous antioxidants which may help with anti-aging, such as vitamin E. Antioxidants help stabilize free-radical molecules. Unstable free-radical molecules may damage your skin cells and accelerate signs of aging.
A study from 2002 found rice to help increase the rate of wound healing. The same study found an improvement of skin barrier function in the patients after taking rice baths.
Numerous in-vitro studies have found rice water to help decrease sun damage by increasing collagen production and inhibiting the process of tyrosinase.
Long story short- tyrosinase is an enzyme that controls melanin production. Our bodies start producing melanin (AKA tanning) when exposed to UV radiation to protect against damage. Rice water is found to partially block this process.
Though more research is needed on rice's ability to help with UV protection, recent studies seem promising.
Wondering why rice is hydrating? The protein in rice have emollient properties. Emollients create a barrier on the skin to trap moisture in, keeping your skin moisturized.
Some rice extract may have mildly-exfoliating properties. These are mainly limited to Oryza Sativa (Rice) Bran and Oryza Sativa (Rice) Germ Powder.
This rice was first cultivated in China over 10,000 years ago. Many cultures throughout Asia have used rice water on skin and hair for centuries.
Learn more about Oryza Sativa ExtractPhenoxyethanol 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.
Gluconolactone 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 GluconolactoneThis ingredient is calcium salt of gluconic acid. It is a humectant, meaning it attracts water to your skin.
