As a cosmetic ingredient, collagen is derived from animal sources, but plant derivatives that act like collagen (pseudo-collagen) and amino acid fragments of collagen such as hydroxyproline are also used. In any form, collagen is a good water-binding agent. Collagen in cosmetics, regardless of the source, has never been shown to have a direct effect on producing or building collagen in skin.
