Water-binding agents in moisturizers are also known as what?

• A. Humectants
• B. Emollients
• C. Surfactants
• D. Occlusives

Answer: (A)

Water-binding agents in moisturizers are humectants. They draw in moisture from the air and from the deeper layers of the skin to keep the surface hydrated, helping the skin feel softer and look plumper. This is different from emollients, which smooth and lubricate by filling spaces between skin cells; from surfactants, which are cleansing or spreading agents; and from occlusives, which form a barrier to lock moisture in. In practice, humectants like glycerin and hyaluronic acid boost hydration, and they’re often paired with occlusives in drier environments to prevent moisture loss.
