Melanin protects the skin—the body’s largest organ and a vital component of the immune system—from the damaging effects of ultraviolet (UV) radiation. When the skin is exposed to UV radiation, melanin production is stimulated in melanocytes, with tyrosinase playing a key role in the biosynthetic pathway. However, disruptions in this pathway caused by UV exposure or aging can lead to excess melanin accumulation, resulting in hyperpigmentation.
