Emollients are substances that help to soften and soothe the skin. They work by forming a protective barrier on the skin's surface, which helps to lock in moisture and prevent dryness. Commonly found in lotions, creams, and ointments, emollients are often used to treat conditions like eczema and psoriasis. These products can be made from various ingredients, including oils, fats, and waxes. Emollients are beneficial for people with dry or sensitive skin, as they can improve skin texture and reduce irritation. Regular use of emollients can lead to healthier, more hydrated skin.
