cosmetic treatment on face or hair
A special cream or liquid you put on your face or hair for some time and then wash off to make it look or feel better.

Learners may confuse this cosmetic sense with a protective face covering. In beauty contexts, 'mask' usually means a cream or gel on the skin or hair, not a cloth or medical mask.
類義語
facial (Refers more generally to a face treatment, often in a salon; not always a thick layer that dries.)
対義語
cleanser (A product used to remove dirt or makeup quickly, not left on the skin like a mask.)

Learners may think of a physical covering. In technical texts, 'mask' is abstract data or a pattern, not an object you wear.
類義語
