Ascorbic Acid Polypeptide
What is Ascorbic Acid Polypeptide?
Ascorbic Acid Polypeptide is a synthetic derivative where ascorbic acid, the active form of vitamin C, is conjugated to a polypeptide chain. This chemical modification improves its stability against oxidation, a common issue with pure ascorbic acid in cosmetic products. Classified primarily as an antioxidant and skin conditioning agent, it is commonly used in serums, creams, and lotions. In formulations, it works by scavenging free radicals to preserve the integrity of other ingredients like oils and fragrances, while also contributing to product shelf life. On the skin, it supports conditioning effects by helping maintain barrier function and hydration balance, promoting softness and flexibility without clogging pores.
