About Glutathione
Topical glutathione is an antioxidant used in skincare products primarily for its potential skin-brightening and anti-aging effects. It works by inhibiting melanin production and neutralizing free radicals. While generally considered safe for topical use, some individuals may experience skin irritation or allergic reactions. The efficacy of topical glutathione can vary widely depending on the formulation, concentration, and individual skin characteristics. Further research is needed to fully understand its long-term effects and optimal usage.
