It’s true that the more melanin (the dark pigment that give skin its colour) skin has, the more it’s naturally protected from damage by the sun’s ultraviolet (UV) rays. On average, medium-dark skin provides an SPF of about 13 and filters twice as much UV radiation as fair skin. However, your skin tone will not protect your skin from free radicals, which can lead to the disruption of DNA, resulting in cancer and pigmentation.

Skin cancer is less prevalent among people of colour, accounting for about 1 to 2 percent of all cancer cases in African-Americans, and about 2 to 4 percent in Asians. In cases where cancer does occur, it occurs in areas that are not normally exposed to the sun, for example soles of the feet, palms of the hands and eyes.
