Symptoms
Perioral dermatitis starts with red rashes around the mouth, a bit down on the chin and under the nose. Sometimes, in rare cases, the rash appears around the eyes. It then develops into small bumps, which may itch and burn a little. Skin affected may peel easily. Contrary to common belief, blackheads are not a symptom of perioral dermatitis.
The condition is more common in women, and may be caused by poor hygiene, peeling and excessive cleaning of the face, strong makeup, prolonged use of cortisone creams and steroid creams, or hormonal changes.
