Glutathione is a powerful endogenous antioxidant clinically associated with melanin inhibition and skin brightening, making it one of the most sought-after actives in Korean brightening skincare. Medicube’s Glutathione Serum harnesses this ingredient in a topical format validated by cosmetic dermatology research for visible skin brightening and broad-spectrum antioxidant protection.
A brightening and antioxidant serum powered by glutathione, widely known as the master antioxidant, to fade hyperpigmentation, even skin tone and protect against oxidative stress. Delivers a noticeably clearer, more radiant complexion through targeted, science-backed brightening action that works at the melanin-production level for visible and progressive results.
Apply evenly across the face after toner and gently press into the skin. Use consistently morning and evening for visible brightening benefits.
