Valine(300 Ppm)
Valine is an essential amino acid and a building block of skin proteins such as collagen. Because it is essential, the human body cannot synthesize it on its own and must obtain it from external sources such as diet. It is a branched-chain amino acid commonly used as a dietary supplement. Its specific role when applied topically to skin is not well established.
