Doctors recommend lotions that contain vitamin A and over-the-counter unscented moisturizers to manage symptoms of ichthyosis, and solutions with urea, lactic or salicylic acid for ichthyosis that causes scaling, according to the Icahn School of Medicine at Mount Sinai. Additionally, petroleum jelly, mineral oil and special soaps also help.
