African Americans and other ethnic groups possessing dark skin, have some skin care challenges with uneven skin tone. Many black skin care products identify these challenges and aim their effect at evening out the troubled skin tone. Having an even-out skin tone element in a black skin care product is a major selling point. Skin tone comes from melanin, the skin pigment that colors ones skin. Light-skinned people can have uneven skin tone because of uneven distribution of melanin under their skin. If the melanin is concentrated you have freckles. Sunshine triggers the production of melanin and this can darken your skin color in general.
