Several skin-bleaching products can be used overnight to lighten skin color. You likely won’t see actual results after only one night of use, but over time — about two to three months — you will notice spots of discoloration fade away and disappear. Regular use of creams that contain active ingredients like hydroquinone, licorice extract and kojic acid will be the most beneficial for making skin lighter.



Hydroquinone

Hydroquinone is the most powerful skin-bleaching cream on the market. It is available by prescription in a higher dose and over the counter in a lighter dose. It works by inhibiting the presence of melanin in the skin and breaking down existing melanin to reveal a lighter color. Though it has been approved for use by the FDA, side effects are possible. For example, some users have reported contact dermatitis after using this product. Hydroquinone is also banned in Europe because of its reputation as a carcinogen. Talk to your dermatologist before using it.

Before bed, wash the affected area, remove any makeup and pat dry. Massage a dime-sized amount of the cream onto the affected area and leave on overnight. Follow this routine on a daily basis and you will begin to see results in about four to six weeks.

Kojic Acid and Glycolic Acid

The combination of kojic acid and glycolic acid is another potent skin-bleaching agent. Kojic acid is derived from a fungal metabolic process and also works by inhibiting melanin production. Kojic acid can be found in many over-the-counter skin-lightening products used overnight to lighten age spots, acne scars and other areas of discoloration on the skin. Like hydroquinone, it has also been reported to have caused contact dermatitis in some users. People with sensitive skin have experienced some irritation. If you have sensitive skin, talk to your dermatologist before using any creams containing kojic acid.

Apply at nighttime over clean skin and massage thoroughly into spots of discoloration. Leave on overnight and wash off with soap and water in the morning. Use for at least a month to obtain desired results.
