Ingredients Side-by-side
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.
Sodium Hyaluronate is hyaluronic acid's salt form. It is commonly derived from the sodium salt of hyaluronic acid.
Phenoxyethanol 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.
Ethylhexylglycerin (we can't pronounce this either) is commonly used as a preservative and skin softener. It is derived from glyceryl.
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.
Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:
Propanediol helps absorb ingredients into your skin, boosting their benefits. It can act as an emollient, making your skin softer. Propanediol can help products last longer by boosting the properties of preservatives within the formulation.
Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.
Sodium Hyaluronate is hyaluronic acid's salt form. It is commonly derived from the sodium salt of hyaluronic acid.
Pentylene 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.
1,2-Hexanediol is a multi-tasker ingredient. It acts as a preservative to increase shelf-life and can aid other preservatives in preventing microbe growth. 1,2-Hexanediol also helps the skin retain moisture as a humectant.
Sodium Polyacryloyldimethyl Taurate is a polymer and used to help stabilize other ingredients.
Betaine is a common humectant (a substance that promotes retention of moisture). It's known to be gentle on the skin and can help balance hydration.
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.
Dimethicone is a silicone used for making products smooth and silky. It also has the added benefit of sealing in hydration. The amount of dimethicone found in beauty products is considered safe and non-comedogenic, meaning it won't clog pores.
This is a synthetic polymer. It helps improve the texture of products by adding thickness and gel-like feel.
Sodium PCA is the sodium salt of pyroglutamic acid and is naturally occurring on human skin.
Sodium Lactate is the sodium salt of lactic acid, an AHA. It is a humectant and used to adjust the pH of a product.
Glyceryl Acrylate/Acrylic Acid Copolymer is made up of glycerin and polyacrylic acid. It helps hydrate your skin as a humectant.
Hydrogenated Lecithin is created from the hydrogenation of lecithin. Hydrogenation is a chemical reaction between molecule hydrogen and another element.
Ethylhexylglycerin (we can't pronounce this either) is commonly used as a preservative and skin softener. It is derived from glyceryl.
Serine is an amino acid naturally found in our body. Our bodies use amino acids to create protein.
Glycine is an amino acid that helps build proteins. It is already present in our skin as our bodies produce them naturally.
Sodium Phytate is the synthetic salt form of phytic acid. Phytic acid is an antioxidant and can be found in plant seeds.
Sorbitan Isostearate is an emulsifer and cleaning agent. It is created from isostearic acid and sorbitol.
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.
4 Benefits 2 Concerns
Citric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).
Threonine is an amino-acid. It helps hydrate the skin and has antioxidant benefits.
Arginine is an amino acid that is important for human development. Your body uses is it to produce hair keratin and skin collagen.
Proline is an amino-acid. It helps moisturize the skin and plays an important role in creating proteins.
Cholesterol is a class of organic molecules called lipids. It helps hydrate your skin and is essential to having a healthy skin barrier.
Caprylic/Capric Triglyceride is an emollient, solvent, and texture enhancer. It is considered a skin-softener by helping the skin prevent moisture loss.
Phytosphingosine is a phospholipid naturally found in our skin. It helps moisturize, soothe, and protect skin.
Stearic Acid is a fatty acid. It is an emollient, emulsifier, and texture enhancer.
Oleic Acid is an Omega-9 fatty acid. It can be found in many plant oils such as avocado and marula oils.

Antioxidant 4 Benefits May cause irritation
Tocopherol (also known as Vitamin E) is a common antioxidant used to help protect the skin from free-radicals and strengthen the skin barrier. It's also fat soluble - this means our skin is great at absorbing it.
6 Benefits 3 Concerns
Lactic Acid is an AHA that is derived from fermenting lactose, a carbohydrate from milk. It removes the top layer of old and dead skin cells and helps increase cell turnover.
Caprylyl Glycol is a humectant and emollient, meaning it attracts and preserves moisture.
