process of adding or retaining water in skin or hair
Moisturizing, also known as hydrating, refers to the process of adding or retaining water in the skin or hair to prevent dryness and maintain a healthy barrier. This is typically achieved through the use of products like creams, lotions, or oils that contain ingredients such as humectants, which attract water, and occlusives, which form a protective layer to lock in moisture. Proper moisturization is essential for maintaining skin elasticity, preventing irritation, and supporting overall skin and hair health.
