Glutamic acid is a non-essential amino acid naturally found in the body and in many proteins. In cosmetics, it functions as a humectant, helping the skin retain moisture, and can also contribute to the skin's natural moisturizing factor (NMF). It is a building block for proteins and plays a role in various biological processes.
