This medication serves as a moisturizer designed to treat or prevent dry, rough, scaly, itchy skin, as well as minor skin irritations like diaper rash and skin burns from radiation therapy. Emollients, the active ingredients in this product, help soften and moisturize the skin while reducing itching and flaking. Some components, such as zinc oxide and white petrolatum, primarily protect the skin from irritation caused by moisture. Dry skin results from a loss of water in the skin's upper layer. This moisturizer works by creating an oily barrier on the skin's surface that retains moisture. Common emollients include petrolatum, lanolin, mineral oil, and dimethicone. Additionally, humectants such as glycerin, lecithin, and propylene glycol attract water into the skin's outer layer. The formula may also contain ingredients like urea and alpha hydroxy acids (lactic, citric, glycolic acids), as well as allantoin, which help to break down keratin, allowing dead skin cells to shed. This process enhances the skin's moisture retention, resulting in a smoother and softer feel.
