Chemical peels remove many "visible signs of aging on the face, hands, neck, and chest. After the skin heals, fewer wrinkles, less discoloration, and improved texture may be seen." There may be temporary swelling, redness or bruising.
Depending of the depth of the peel, one can expect to see the improvements between one and fourteen days.
Sadly, most results are not permanent so the patient needs to explicitly follow their board-certified dermatologist's instructions as well as protect skin from sun exposure.
