Perioral dermatitis is a type of rash that typically presents as pink papules (small red bumps) and scaling around the mouth. In addition to affecting the area around the mouth, it can also appear around the nose or eyes and can be referred to as periorificial dermatitis. The exact cause of perioral dermatitis is unknown. However, the use of inhaled and topical steroids can trigger the condition. Though anyone can get perioral dermatitis, it is most common in young women and children. Treatment options include prescription topical medications and oral antibiotics.
