Skin Conditions and Perioral Dermatitis

Perioral dermatitis is a facial rash that causes bumps to develop around the mouth. In some cases, a similar rash may appear around the eyes, nose, or forehead. The condition is most commonly seen in young women (90% of cases), but it can affect men as well.

Call Your Doctor About a Rash if:

  • Your rash stays red and itchy for more than a week; you may have another type of contact dermatitis or eczema.
  • You have the rash near your eyes or the rash covers a large part of your body. You may need medical attention.
  • You have severe complications, such as generalized swelling, headache, fever, or a secondary infection.
  • You have been exposed to the smoke from burning poison ivy, poison oak, or poison sumac. The toxin is not destroyed by fire and can cause severe allergic reactions.
  • Call 911 if you have trouble breathing.
