Role of protein in cosmetics

Abstract 

Many authors recognize the beneficial effects of using protein-rich substances in formulations of various topical applications. Proteins quickly were considered useful ingredients for creating a suitable environment for healthy skin and hair because of their ability to bind water with the horny layer of skin and its annexes. Most protein derivatives that are used for cosmetic purposes are obtained from simple proteins, whereas conjugated proteins are used far less frequently. In this article, the role and efficacy of proteins used in cosmetics are reported and discussed.
