Glycine(2,500 Ppm)

Glycine is a non-essential amino acid and one of the building blocks of skin proteins such as collagen and elastin. The body can produce it naturally, but its production decreases with age. It is classified as a skin-identical ingredient and functions primarily as a moisturizer when applied topically. It also serves as a structural component of several well-known peptides, including copper-tripeptide-1, palmitoyl tripeptide-1, and palmitoyl hexapeptide-12.
