Rash of the skin around the mouth.
The exact cause of perioral dermatitis is unknown. Misuse of steroid creams may play a role.
Small, pus-filled bumps and mild peeling of the skin around the mouth are symptoms. The condition can also affect the skin around the nose, cheeks, and eyes.
Self-care steps, medicated creams, and medicine taken by mouth can help treat perioral dermatitis.
