Tetrahexyldecyl Ascorbate: ingredient no. 1, not counting water
An antioxidant. Derivatives differ in stability.
Polyhydroxy acids. The molecule is larger than the AHAs', they penetrate more slowly and also work as humectants; an acid routine is often started with these.
Ingredients fermented with microorganisms: yeast, lactic acid bacteria, and bifido filtrates. Common in Korean and Japanese essences, where they act as humectants.
A large protein that stays on the skin surface as a hydrating film former; hydrolyzed forms and collagen amino acids act as humectants. The ingredient is often used in formulations aimed at aging skin.
