DOES ETHNIC SKIN AGE SLOWER THAN NON-ETHNIC SKIN?

Generally speaking yes. However, hereditary factors play a major role. The reason why ethnic skin ages slower than non-ethnic skin is because the melanin found in ethnic skin, which filters out the sun's harmful ultraviolet rays, provides it with a natural sun protection. This is why dark skin, black especially, is more protected against premature wrinkling from sun exposure and skin cancer. Also, dark skin is usually thicker than light skin and thicker skin does not show signs of aging rapidly as thinner, more delicate skin. Thus, due to the thickness of the skin and the larger, more plentiful sebaceous glands linked with dark skin, fine lines and wrinkles are less noticeable.
