Skin whitening
Skin whitening is the practice of using substances, mixtures, or physical treatments to lighten skin color. Skin whitening treatments work by reducing the content of melanin of the skin. Many agents have been shown to be effective in skin whitening; some have beneficial side effects (e.g.: are antioxidants, nutrients, or decrease the risk of some types of cancer); some are a significant risk to health (for example, those containing mercury).
