Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.
Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:
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.
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.
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.
Carbomer is a polymer of acrylic acid. Its main role is to create gel consistency within products.
Caprylyl Glycol is a humectant and emollient, meaning it attracts and preserves moisture.
Allantoin plays a role in soothing and moisturizing the skin. Because of this, it is often added to products with strong active ingredients.
Tromethamine is an aliphatic compound. An aliphatic compound is an organic compound with open-chained carbon atoms. It is synthetically created. Tromethamine is used to balance pH and improve texture.
Ethylhexylglycerin (we can't pronounce this either) is commonly used as a preservative and skin softener. It is derived from glyceryl.
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.
Panthenol is a common ingredient that helps hydrate and soothe the skin. It can be found naturally in our skin and hair.
Malachite extract is created by grinding down the malachite stone.
Hydrolyzed Hyaluronic Acid is a form of hyaluronic acid. It is created by the hydrolysis of hyaluronic acid with a high molecular weight. Once created, Hydrolyzed Hyaluronic Acid has a low molecular weight.
Disodium EDTA plays a role in making products more stable by aiding other preservatives.
Glyceryl Acrylate/Acrylic Acid Copolymer is made up of glycerin and polyacrylic acid. It helps hydrate your skin as a humectant.
Sodium Hyaluronate is hyaluronic acid's salt form. It is commonly derived from the sodium salt of hyaluronic acid.

Low molecular weight HA has been shown to hydrate and increase elasticity of the skin. Increasing elasticity is also associated with reduction of wrinkle depth.
One study found topical low molecular weight hyaluronic acid may be considered for the treatment of rosacea in the adult population. However, we always recommend speaking with a professional about your skin concerns.
Hyaluronic acids are a humectant. This means they draw moisture from the air. Hyaluronic acids help moisturize, soothe, and protect the skin.
