Dark brown spots on your face or body are known as hyperpigmentation, which is caused by the overproduction of melanin that creates small deposits in your skin. If the pigment cells become damaged by ultraviolet (UV) rays, it also may cause excessive melanin production, according to Daniel Yarosh, author of "The New Science of Perfect Skin." You may try various treatments to remove the dark pigmentation.
Obtain bleaching cream containing the active ingredient hydroquinone from a doctor's prescription or over the counter (which will contain a smaller percentage). Place a small amount of the bleaching cream onto a cotton swab and dab the dark pigmented area of your skin. Avoid getting the cream on areas that are not dark, as it will lighten anything it touches.
Re-apply the bleaching cream twice daily or as directed in the medication's instructions, so that you will not experience skin irritation. Once the medication is applied to the pigmented skin, avoid sun exposure for at least an hour.
Apply a thick layer of sunscreen with SPF 15 or higher to the darkly pigmented area whenever you are outside, as sun exposure increases skin pigmentation, according to Leslie Baumann, M.D., author of "The Skin Type Solution."
Consult your doctor about laser therapy. According the to American Osteopathic College of Dermatology, laser treatments may remove the dark pigmentation using a q-switched ruby laser. The laser burns a thin layer of skin from the surface to remove the dark spot. This treatment may cause inflammation after the procedure, but should subside within three days, according to Yarosh.
Apply a cold compress to your face to reduce redness and swelling after treatment. Laser therapy should be not be used if you have darker skin, as it can worsen the dark pigmentation.
Sleep with at least two pillows to keep your head elevated for one to two weeks after your treatment, according to the Facial Plastic Surgery. Laser treatment should be a last resort for removing dark pigmentation, as some lasers may cause scarring.
Carrot Salad Mask
Shred one carrot into a small mixing bowl, and mix with lemon juice. According to Narine Nikogosian, author of "Return to Beauty," lemon juice is a natural skin bleaching agent, while carrots protect your skin from the sun.
Dip a clean cloth into the mixture and apply it to the dark pigmentation.
Allow the mask to set on your skin for 20 minutes, then rinse it off with warm water.
Apply a thin layer of moisturizer with SPF 15 onto your face to protect your skin after treatment.
