Product Description:<\/b> <\/span>Vitasome GL is L-Glutathione, a naturally occurring tripeptide composed of glutamine, cysteine, and glycine<\/span><\/span>. <\/span>As a primary endogenous antioxidant, it protects cells from oxidative stress and maintains redox balance<\/span><\/span>. <\/span>It exists in both reduced (GSH) and oxidized (GSSG) forms, with the reduced form being biologically active<\/span><\/span>. <\/span>Beyond its antioxidant role, L-Glutathione is recognized for its skin-brightening properties by inhibiting melanin synthesis, making it a popular ingredient in skincare for promoting an even skin tone and reducing hyperpigmentation<\/span><\/span>.<\/span><\/p>\n
