Humectants are substances that attract and retain moisture from the environment. They are commonly used in skincare products, such as lotions and creams, to help keep the skin hydrated. By drawing water into the skin, humectants can improve its texture and appearance, making it look plumper and more youthful. Common examples of humectants include glycerin, hyaluronic acid, and aloe vera. These ingredients are often found in both cosmetic and food products, as they help maintain moisture levels. In addition to skincare, humectants are also used in baking to keep baked goods soft and fresh.
