Moisturizers are skincare products designed to hydrate and protect the skin. They work by sealing in moisture and preventing dryness, making the skin feel soft and smooth. Moisturizers come in various forms, including creams, lotions, and gels, and can be tailored to different skin types, such as oily, dry, or sensitive. Using a moisturizer regularly can help maintain the skin's natural barrier and improve its overall appearance. Many moisturizers also contain beneficial ingredients like hyaluronic acid or glycerin, which attract water to the skin, and sunscreen to protect against harmful UV rays.
