Perioral dermatitis is a common facial skin problem in adult women. It rarely occurs in men. It may occasionally affect children. Groups of itchy or tender small red papules (bumps) appear most often around the mouth. They spare the skin bordering the lips (which then appears pale) but develop on the sides of the chin, then spreading to include upper lip and cheeks. The surrounding skin may be pink, and the skin surface often becomes dry and flaky.
