Early salicylic late: Early on, salicylic acid and Hydrocortisone cream preparations may limit inflammation which can produce hyperpigmentation. Late pigmentation can be treated with bleaching agents such as hydroquinone in combination with a retinoid and steroid. Alternatively, some chemical peels or fractionated laser treatments can also produce nice results. Only rarely is surgery needed.
