Which of the following is considered a nonsetting mask?

• A. Sheet mask
• B. Clay mask
• C. Peel-off mask
• D. Gel mask

Answer: (A)

Nonsetting masks stay pliable and don’t form a hard film on the skin. A sheet mask fits this idea because it’s a fabric sheet saturated with serum that sits on the face for a short time and is removed after use, without drying into a solid film. The other types—clay masks dry down and harden, peel-off masks create and later lift off a film, and gel masks typically stay moist or rinse off rather than set into a film. So the sheet mask is the nonsetting option.
