Hydroquinone Powder is a skin-lightening agent. It bleaches the skin, which can be helpful when treating different forms of hyperpigmentation.
Hydroquinone is used to lighten the dark patches of skin (also called hyperpigmentation, melasma, "liver spots," "age spots," freckles) caused by pregnancy, birth control pills, hormone medicine, or injury to the skin. This medicine works by blocking the process in the skin that leads to discoloration.
