Protective creams are topical products designed to create a barrier on the skin, shielding it from harmful substances and environmental factors. They are commonly used to prevent irritation from chemicals, moisture, and friction, making them beneficial for people with sensitive skin or those working in harsh conditions. These creams often contain ingredients like glycerin, petrolatum, or dimethicone, which help to lock in moisture and maintain skin integrity. They can be applied before exposure to irritants or after to soothe and protect the skin. Regular use can help reduce the risk of skin damage and promote overall skin health.
