What it is
Melanin is the family of dark biological pigments responsible for color in skin, hair, and many other natural materials, and it has light-absorbing and antioxidant characteristics. In cosmetic formulas the ingredient labeled melanin is used at low levels as a conditioning component, sometimes positioned around its natural pigment and free-radical-scavenging properties. It is incorporated according to its solubility and the formula design.
