While there are many medical treatments that can be used to help lighten the skin, including chemical peels and dermabrasion, these remedies are expensive and somewhat invasive. However, there are some natural home remedies that can help to lighten black skin without the use of chemicals or medical treatments. These remedies have not been approved by the FDA, however, so consult your doctor or dermatologist before trying any of them on yourself.
