Perioral Contact Dermatitis
Perioral dermatitis is characterized by small, red, pus-filled bumps around the mouth. A burning sensation may occur at the affected area. The most affected areas are the chin, sides of the lips, and lines from the nose, however, the lesions may occasionally spread around the nose, eyes, and cheeks.
It is neither acne nor rosacea, but the red lesions pose a resemblance to these conditions. It usually affects young women between the ages of 20 to 45, who account for 90% of all cases. [1] Men and children can also be affected.
The exact cause remains unknown, but experts believe that some factors may lead to the development of perioral dermatitis. The most common factor is the use of corticosteroid creams; other factors include the use of fluorinated dental products, moisturizers, sunscreen, and makeup. It is also believed to be a form of rosacea or sebhorreic dermatitis.
The doctor can usually make an accurate diagnosis of perioral dermatitis through a thorough examination of the skin. In some cases, laboratory tests may be needed to eliminate the possibility of other conditions that may pose similar symptoms. [2]
Perioral dermatitis is only limited to the skin and is not a life-threatening condition, however, when left untreated, the condition may last for months to years. It may also cause emotional problems due to its disfiguring nature.
Some prevention tips include discontinuing use of creams that contain steroid, fluorinated dental products, and other facial products that might cause irritation. Treatment may last for several months and is usually in the form of topical medications such as metronidazole, erythromycin, or benzoyl peroxide. In severe cases, oral antibiotics may be required. Flare-ups may occur when corticosteroid creams are applied to the face.
