Glutathione inhibits melanin production, leading to a lighter skin tone, reduced hyperpigmentation, and improved skin radiance. Effectiveness varies based on product, concentration, and individual skin.
Glutathione inhibits the activity of tyrosinase, a key enzyme in the melanogenesis pathway. This inhibition reduces the production of melanin, the pigment responsible for skin color. Consequently, reduced melanin synthesis can lead to a lighter skin tone, diminished hyperpigmentation (such as sunspots and age spots), and an improvement in overall skin radiance and evenness. The effectiveness of skin brightening/whitening products varies substantially depending on the specific product formulation, the concentration of the active ingredient (e.g., glutathione), the method of delivery (topical, oral, intravenous), and the unique characteristics of an individual's skin.
