chosen: You can lighten your skin by using a bleaching cream that contains hydroquinone, kojic acid, or azelaic acid. You should also wear sunblock regularly to protect your skin, and avoid exposure to UV rays as much as possible. It may take several weeks or months to see the full effect, but it is generally a safe and effective way to lighten your skin.
