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.
Hydroquinone works by blocking the process in the skin that leads to discoloration.
Follow all directions on the product package, or use as directed by your doctor. Before using, apply a small amount of hydroquinone to an area of unbroken skin, and check the area within 24 hours for any serious side effects. If the test area is itching, red, puffy, or blistering, do not use hydroquinone and contact your doctor. If there is just mild redness, then treatment with hydroquinone may begin.
Apply hydroquinone to the affected areas of skin, usually twice daily or as directed by your doctor. Hydroquinone is for use on the skin only. If it is used incorrectly, unwanted skin lightening may occur. Avoid getting hydroquinone in your eyes or on the inside of your nose or mouth. If you do get hydroquinone in those areas, flush with plenty of water.
Hydroquinone may make the treated areas of skin more sensitive to the sun. Avoid prolonged sun exposure, tanning booths, and sunlamps. Use sunscreen and wear protective clothing on the treated areas of skin when outdoors.
Use hydroquinone regularly to get the most benefit from it. To help you remember, use it at the same times each day.
Inform your doctor if your condition persists or worsens after 2 months.
