A skin protectant is a product designed to create a barrier on the skin, helping to shield it from irritants, moisture loss, and environmental factors. These products are often used to prevent or treat skin conditions such as dryness, chafing, and minor abrasions. Common ingredients in skin protectants include petrolatum, dimethicone, and zinc oxide, which work to lock in moisture and promote healing. Skin protectants are commonly found in various forms, including creams, ointments, and lotions. They are frequently recommended for use in sensitive areas, such as around the nose, elbows, and hands, especially in conditions where the skin is exposed to harsh elements or frequent friction.
