Reduced Glutathione is the biologically active form of this well-known tripeptide, valued in cosmetic systems for its ability to help reduce oxidative stress and support a more radiant, balanced-looking complexion.

Supplied as a cosmetic raw material for formulation use only.

What It Does

Reduced Glutathione (GSH) functions as a powerful intracellular-style antioxidant, helping neutralize reactive oxygen species and supporting skin exposed to environmental stress such as pollution and UV exposure. In topical systems, it is commonly used to promote a brighter, more even-looking complexion while reinforcing overall antioxidant networks.

Because it is supplied in the reduced (active) state, GSH delivers direct redox activity, making it preferred over oxidized forms for advanced cosmetic formulations.
