Various topical, oral, and injection-based cosmetic skin-lightening agents with different mechanisms of action are used widely across Asia, including hydroquinone, azelaic acid, kojic acid, mulberry, alpha-arbutin, beta-arbutin, glutathione, licorice root, papaya, vitamin A (e.g., retinol), vitamin B (i.e., niacinamide), and vitamin C.1,2 One of the widely used systemic agents is glutathione, which is a thiol compound and a regulator of the melanogenic pathway in humans.3 Glutathione is an antioxidant found in the human body, contributing to drug and xenobiotic detoxification.3,4 It is known to be antimelanogenic, thereby associated with melanin production.5,6 It also inhibits tyrosinase activity and melanosome transfer from melanocytes to keratinocytes.48 Overall, it is suggested that glutathione might promote pheomelanin synthesis, inhibit intracellular melanogenic enzymes, and exhibit antioxidant and anti-aging effects.3 As demonstrated in in-vitro experiments, glutathione is associated with melanogenesis
