Proline

Description

Proline is an amino acid that is used as a building block in the production of proteins. In cosmetics, proline is primarily used as an antioxidant component due to its ability to improve skin elasticity, increase collagen production, and aid in skin repair and regeneration. Proline is often used in anti-aging skin care products for its ability to reduce the appearance of fine lines and wrinkles. Specifically, proline is a substrate necessary for collagen synthesis. Collagen has a triple helix structure composed of proline, hydroxyproline, and glycine. Of all the amino acids that make up collagen, the effects of proline on skin health have been best studied. It is well known that proline can help restore damaged skin and aid in wound healing due to its ability to support collagen synthesis.
