The master antioxidant ~ and Korea’s most powerful brightening active.
Glutathione is produced naturally by the body ~ a tripeptide of glutamine, cysteine, and glycine that neutralises free radicals, supports cellular repair, and plays a central role in the skin’s own pigmentation regulation. As a topical skincare ingredient, it works by inhibiting tyrosinase ~ the enzyme central to melanin production ~ while simultaneously switching melanin synthesis from the darker eumelanin pathway to the lighter phaeomelanin pathway. The result is comprehensive brightening that addresses existing pigmentation and prevents new pigmentation from forming simultaneously.
Korea has been at the forefront of glutathione skincare formulation ~ developing stabilised, bioavailable forms of the ingredient that can be delivered topically at concentrations that produce visible results, paired with tranexamic acid, niacinamide, and vitamin C in brightening systems that address hyperpigmentation across every pathway simultaneously.
Glutathione is not a surface brightener. It works at a cellular level ~ and the results that build over consistent use are measurably different from the brightening actives that preceded it.
Best for: hyperpigmentation, dark spots, melasma, dullness, uneven tone, post-inflammatory pigmentation.
