What it is

GABA, gamma-aminobutyric acid, is an amino-acid neurotransmitter used topically in cosmetic formulations targeting the appearance of expression lines. Cosmetic claims focus on a transient muscle-relaxation effect at the skin surface; the molecule is a peripheral GABA-receptor ligand. Pairs broadly with most actives. No major conflicts.
