Abstract
In a process for bleaching chemically tanned skin and discolored nails, a bleaching composition is applied to the skin or nails to be bleached or lightened. The applied composition may be left undisturbed or may be rubbed into the skin continuously. The treatment period is about 30 seconds to 10 minutes in the case of skin, and about 5 minutes to 30 minutes in the case of nails. Thereafter the applied composition is removed from the skin or nails by a combination of towel wiping and water rinsing. The bleaching composition may include a bleaching agent comprising hydrogen peroxide and may include an activator comprising ammonium bicarbonate. The bleaching composition may also include an exfoliant comprising fine abrasive particles such as ground walnut shells, pumice or sand.
