What is a primary function of kaolin in skincare?

• A. Astringent and toning effect
• B. Moisturizing cream base
• C. Absorbent properties
• D. UV protection

Answer: (C)

Kaolin’s primary function in skincare is its absorbent properties. As a fine clay, it has a large surface area that draws in and holds onto oils, dirt, and dead skin cells when used in masks or cleansers. This makes it excellent for mattifying oily or congested skin and helping to purify the surface without adding moisture. It isn’t used as a moisturizing base, it doesn’t provide UV protection, and any tightening sensation is temporary and not the main action. So the standout benefit is its ability to absorb excess oil and impurities.
