Prolonged exposure to the sun induces melanin dispersion, which in turn acts as a natural sunscreen. Melanin is a pigment that is produced by melanocytes in the skin and provides protection against UV radiation by absorbing and scattering it. Prolonged exposure to the sun causes the melanin granules to cluster around the nucleus of the keratinocytes, creating a protective barrier. This process is known as melanin dispersion.
