Proline (Proline)

An amino acid used in cosmetic formulations as a skin and hair conditioning ingredient, valued for its role in supporting hydration, softness and a more elastic-looking appearance. As one of the amino acids associated with the structural proteins of the skin, it helps improve the look and feel of dry, mature, dehydrated or tone-lacking skin, contributing to a smoother, more supple and well cared-for surface. In creams, serums, lotions, restorative formulas and hair care products, it enhances the conditioning character of the product, supports skin comfort and complements the amino acid profile of the formula, giving both skin and hair a softer, more balanced and revitalized cosmetic finish.
