Lotion is a creamy or liquid substance applied to the skin to moisturize, protect, or soothe it. It often contains water, oils, and other ingredients that help hydrate the skin and improve its texture. Lotions can be used for various purposes, including treating dry skin, sunburn, or irritation. Many lotions are formulated for specific skin types, such as dry skin or sensitive skin. They may also include added benefits, like sunscreen for sun protection or fragrance for a pleasant scent. Regular use of lotion can help maintain skin health and prevent dryness.
