Glycine
GlycineHydrator
A small amino acid used as a humectant and pH buffer that helps hold water at the surface.
What it does
Glycine is the simplest amino acid and a component of skin's natural moisturizing factor. As a humectant it attracts and holds water at the surface, and it can help buffer a formula's pH. It is a hydration-and-formulation ingredient rather than a skin active.
