What Is Gamma-Aminobutyric Acid?
Gamma-aminobutyric acid (GABA) is a naturally occurring amino acid that works as a neurotransmitter in the brain. In skin care, it is claimed to have anti-ageing and skin-soothing benefits. Some studies suggest that GABA can help to reduce the appearance of fine lines and wrinkles, and may also have a calming effect on the skin. However, more research is needed to fully understand its effects on the skin.
