What substances are known to absorb moisture or promote water retention?

Humectants are substances that have the ability to attract and retain moisture from the environment. They work primarily by drawing water from the air into the skin or hair, helping to maintain hydration levels. In the context of cosmetology, humectants are especially important for products designed for moisturizing skin or hair, as they can significantly enhance the product’s effectiveness by keeping the area hydrated.

Common examples of humectants include glycerin, hyaluronic acid, and aloe vera, all of which are often used in skincare and haircare formulations to provide hydration. Their role is crucial, particularly in dry conditions or for individuals with dry skin or hair, as they help to counteract moisture loss. This makes humectants a vital component in many beauty products.
