Collagen Amino Acids Buono Umettante Idratare Collagen Amino Acids at a glance Help hydrate skin Serve as humectants Can help improve skin health Created through the hydrolysis of collagen Collagen Amino Acids description Collagen amino acids help hydrate skin due to their humectant nature. They’re created through the hydrolysis (breaking down with water) of collagen proteins, which results in a high amount of a single amino acid, hydroxyproline; however, other amino acids, like glycine and proline, are also present in smaller amounts. Hydroxyproline serves to increase skin’s moisture levels and smoothness. Research also suggests that topically applied hydroxyproline and glycine (derived from fish collagen) can have a positive impact on healthy skin cell maturation. Collagen amino acids may be synthetic or animal-derived. Collagen amino acids are also used in the supplement industry in pill, gummy and powder forms. The Cosmetic Ingredient Review Expert Panel reviewed collagen amino acids and determined them safe for use in cosmetics at current concentration levels (0.0003%-6.0%). Those who are vegan should check with the brand to ensure the collagen amino acids they’re using are not animal-derived. Related ingredients: Vegetable Collagen
