Brown skin can be lightened by using products like bleaching creams. Skin brighteners and whiteners also help lighten brown skin.
All of the products mentioned work by reducing the melanin in the skin. People with dark skin have more melanin, but exposure to the sun and other environmental factors can also contribute to darker skin. The products can be obtained by a prescription, and some with weaker strength medications are available over the counter. All medications designed to lighten the skin carry risks. For instance, some bleaching creams contain mercury, which can lead to poisoning and kidney problems if too much is absorbed through the skin, according to WebMD. Because of this, bleaching products containing mercury are banned in the U.S.
