Causes and Solutions
This condition can be caused by an accumulation of dead cells on the skin, so exfoliate your knees regularly. If you aren't regularly cleaning your knees, or are frequently rubbing them or rubbing them against something, this also can cause darkness.
Try this home remedy: Mix 1 teaspoon each of lemon juice, vitamin E and glycerin in 4 tablespoons of milk. Massage this paste onto the dark areas of your knee. Leave the paste in place for 15 minutes, and then rinse with warm water.
Mix lime juice and coconut oil together and apply to your knees. Or slice a lime or lemon and rub it against the darkened area.
Scrub your knees with a pumice stone, but make sure you that you don't scrub too hard. Moisturize afterward. Rub the area with mustard oil and then rinse clean.
Keep your knees moisturized all the time, which can prevent the dark spots in the first place. Use cocoa butter or honey as moisturizer.
Cut open an aloe plant and rub the fleshy inside part of the plant against your discolored knees. Try using a mixture of yogurt and chickpea flour, which creates a thick paste. Massage your knees with this mixture. Let it dry and then rinse with warm water.
Consider skin lightening products such as Meladerm or Revitol. Meladerm contains lemon juice, lactic acid, licorice extract, kojic acid, alpha-arbutin extract and emblica powder, and should lighten your knees in two to three weeks. Revitol is made of shea butter, evening primrose oil and grapefruit extract. Follow the directions for use.
Consider using Skin Glow, an ointment made of kojic acid and alpha-arbutin, which are powerful bleaching agents. This product also nourishes and moisturizes your skin.
