What ingredient is commonly included in a mask specifically formulated for oily skin?

  1. Kaolin

  2. Bentonite

  3. Glycerin

  4. Hyaluronic acid

The correct answer is: Bentonite

A mask specifically formulated for oily skin often includes bentonite, which is a type of clay. Bentonite clay is known for its absorbent properties, effectively drawing out excess oil and impurities from the skin. This can help to prevent clogged pores, reduce shine, and promote a clearer complexion, making it a popular choice for managing oily skin conditions. While kaolin is also a clay that can be beneficial for oily skin, bentonite has a stronger oil-absorbing ability, making it more effective for this specific purpose. Glycerin and hyaluronic acid, on the other hand, are hydrating ingredients often used for dry skin or to maintain moisture levels in the skin, which may not be suitable for someone struggling with excess oil production. Thus, bentonite is the most appropriate ingredient for a mask targeting oily skin concerns.
