Gamma Aminobutyric Acid
What is Gamma Aminobutyric Acid?
Gamma-aminobutyric acid, commonly known as GABA, is a naturally occurring non-protein amino acid that serves as the main inhibitory neurotransmitter in the human brain. In cosmetics, it is typically produced synthetically and classified as a skin conditioning agent and humectant according to regulatory databases like EU CosIng. It appears in anti-aging serums, creams, and masks, where it functions by potentially binding to GABA receptors in the skin. This interaction may promote relaxation of facial muscles involved in expression lines, while its humectant properties help attract and retain moisture. Additionally, it acts as an antistatic agent to reduce surface charge on skin and hair. Studies from peer-reviewed sources indicate topical application can influence skin firmness through these mechanisms, making it a popular ingredient in products aimed at mature skin.
