Perioral dermatitis is a skin disorder characterized by tiny red papules (bumps) around the mouth.

Causes, incidence, and risk factors

Perioral dermatitis most commonly affects young women. However, it may sporadically affect men. While its exact cause is unknown, it may appear after topical steroids are applied to the face to treat other conditions.

Signs and tests

Your physician will likely diagnose perioral dermatitis based upon the appearance of your skin. A culture for bacteria may sometimes be needed to eliminate the possibility of infection.

Treatment

In almost all cases of perioral dermatitis, steroid creams should be avoided. Your physician may chose to treat these lesions with topical medications, such as metronidazole, erythromycin, benzoyl peroxide, tacrolimus, or pimecrolimus. In more severe cases, oral antibiotics (such as tetracycline, doxycycline, minocycline, or erythromycin) may be required.

Expectations (prognosis)

Perioral dermatitis is a difficult condition to treat effectively, often requiring several months of treatment. Recurrences are not uncommon, particularly if topical steroids are reapplied to the face.

Calling your health care provider

Call your physician if you notice persistent red bumps around your mouth.

Prevention

Avoid using any topical steroids on your face, unless specifically directed by your dermatologist.
