Halobetasol should not be used on the face or for acne because it is a super-high potency topical corticosteroid. The skin on the face is quite thin compared with the skin on other areas of the body and using halobetasol on the face can increase the risk of acne and other side effects such as dryness, irritation, itching, redness, red or purple blotches underneath the skin, skin discoloration or thinning, small red or white bumps or a rash around the mouth, or unwanted hair growth.
