Choose a liquid, gel or light milk sunscreen. Wash the face with warm water alone while the rash is present. When it has cleared up, wash with an ordinary toilet soap and water. Your doctor or dermatologist will usually also prescribe a course of oral antibiotics for six to twelve weeks. Normally tetracycline or one of its derivatives is recommended.
Antibiotic lotions tend to be less effective.
Perioral dermatitis sometimes recurs when the antibiotics are discontinued, or at a later date. The same treatment can be taken again.
