Glutathione in dermatology: A bright future or fading hype?
Year: 2025
Type: article
Abstract: Glutathione, a potent endogenous antioxidant, has garnered significant attention in dermatology for its purported skin-lightening and anti-aging benefits. While its mechanisms – primarily inhibition of tyrosinase and modulation of melanogenesis – suggest potential efficacy, clinical evidence remains mixed. Several studies have demonstrated its ability to reduce pigmentation and improve skin health when administered orally or topically, yet inconsistencies in outcomes and concerns over bioavailability persist. Furthermore, the safety of intravenous administration remains controversial, with reports of adverse effects prompting regulatory warnings. Different dosing schedules, duration of use, and the longevity of effects remain areas of ongoing investigation. This viewpoint critically examines the current evidence on glutathione’s dermatological applications, weighing its benefits against potential risks. Given the ethical and medical implications, further high-quality research is needed to establish standardized protocols, optimal dosages, and long-term safety profiles.
