There are many skin care products available to lighten skin color. In the United States, there are two types of products available, lightening and bleaching. Lightening products work by "cutting" pigment and turning it into melanin, which is what gives skin a color. Blemishes that result from bleaching products are usually more pronounced, and can be more visible, compared to lighter skin, because they're more dark.
The two types of bleaching products are retinol and benzoyl peroxide. Retinol bleaches with ultraviolet light. Benzoyl peroxide bleaches with the lightest form of vitamin A. Bleaching products are the most popular and effective way to lighten dark skin. The American Academy of Dermatology (AAD) suggests that bleaching products should contain at least 15 percent benzoyl peroxide, with the remainder consisting of retinol. Retinol may be better for people with lighter complexions than benzoyl peroxide, but benzoyl peroxide also works well for dark complexions. Benzoyl peroxide should not be used on areas that have already been bleached or are in poor condition.
