Melanin is a natural shield or an umbrella that protects the nucleus of every cell in the skin when exposed to direct sunlight. The result is that melanin absorbs solar radiation, free heat, and the skin tans, colors with more intensity. The melanin are responsible for producing specialized cells called melanocytes. Faced with an excess of sun, the activity of melanocytes is revolutionary, it produces an excess of melanin and appear stains.
