People with higher skin antioxidant levels have greater protection against UV-induced hyperpigmentation. UV radiation and oxidative stress cause uneven melanin distribution in the skin, resulting in dark spots commonly called age spots or sun spots. Caffeine's primary mechanism against hyperpigmentation is antioxidant action: neutralizing free radicals reduces oxidative signals that drive excess melanin production. Topical caffeine adds to local antioxidant capacity in the skin.
