Prolonged exposure to the sun induces melanin dispersion, which in turn acts as a natural sunscreen. Melanin is produced by melanocytes in the skin and provides protection against UV radiation by absorbing and scattering it. When the skin is exposed to sunlight, melanocytes increase the production of melanin and disperse the existing melanin in the surrounding keratinocytes, thus providing increased protection against UV damage.
