Melanin
What is Melanin?
Melanin is a complex, heterogeneous biopolymer pigment derived from the amino acid tyrosine, naturally synthesized in skin cells called melanocytes. In cosmetics, it appears as a synthetic version or from controlled biological sources, primarily featured in skincare products such as moisturizers, creams, and lotions. Chemically, it consists of indole-based units forming a stable, insoluble structure. Functionally, it operates as a skin conditioning agent by adsorbing moisture and forming a lightweight film that preserves skin's softness, smoothness, and elasticity. As a skin protecting ingredient, it reinforces the skin's surface barrier, helping to deflect external irritants like pollutants and minor dehydrants. This dual role supports overall skin resilience in everyday formulations without influencing color or tone.
