Liver spots - also known as age spots and solar lentigines - may be eliminated with bleaching creams, laser and intense pulsed light therapy, cryotherapy, dermabrasion or chemical peel, according to Mayo Clinic. However, the flat spots are not harmful and require no medical treatment.
Liver spots are most common in adults over the age of 50, though younger persons spending a lot of time in the sun are also susceptible. The spots may be tan, brown or black in color and typically appear in the areas exposed to the sun most - the face, hands, shoulders and arms, explains Mayo Clinic
Prescription bleaching creams may be used independently or with retinoids and a steroid; over the course of several months, a gradual fading of spots can be expected. Laser and intense pulsed light therapy helps to destroy melanin-producing cells without damaging the skin surface and may require several sessions. Cryotherapy involves applying liquid nitrogen to age spots to destroy extra pigment and is most effective on single and small groupings of age spots. With dermabrasion, the surface layer of the skin is sanded down with a rapidly-rotating brush to encourage new skin growth. Chemical peels use an acid to burn the outer layer of the skin, with new skin taking the place of skin as it peels.
Temporary itching, redness, burning or dryness of the skin is common with most treatments, as is a small risk of permanent discoloration or scarring, states Mayo Clinic.
