A moisturizer is a skincare product designed to hydrate and lock in moisture to the skin, helping it stay soft, smooth, and healthy. It works by creating a barrier that prevents water loss and restores moisture to dry or dehydrated skin. Moisturizers come in various forms, including creams, lotions, gels, and oils, catering to different skin types and needs. Some moisturizers also contain additional ingredients like antioxidants, vitamins, or SPF for added benefits, such as protecting the skin from environmental stressors or signs of aging. Regular use of a moisturizer helps maintain the skin’s natural balance, preventing dryness, irritation, and flakiness.
