User:Mr. Ibrahem/Perioral dermatitis

Perioral dermatitis a type of skin rash that typically occurs around the mouth, eyes, and nostrils. Symptoms include multiple small (1–2 mm) red bumps and blisters sometimes with a scaly background. Itching or burning may also be present. Less commonly the genitalia may be involved. Immediately around the lips is generally spared.

The cause is unclear. Topical or inhaled steroids are associated with the condition and moisturizers, cosmetics, fluoridated toothpaste, and sunscreen may contribute. Diagnosis is generally based on symptoms, with a skin biopsy used in unclear cases. Other conditions that may appear similar include rosacea, acne, allergic dermatitis, and lip licker's dermatitis.

Treatment is typically by stopping steroid creams, cosmetics, and sunscreen. Rapidly stopping steroids may initially worsen the rash and thus slowly stopping may be recommended. Initial medications that may be used include metronidazole or clindamycin cream. If this is insufficient doxycycline, tetracycline, or isotretinoin by mouth may be used. It may take a few weeks or month to improve. It can be long-term or recurring.

The condition is estimated to affect 0.5-1% of people a year in the developed world. Up to 90% of those affected are women between the ages of 15 and 45 years. The term "dermatitis" is a misnomer because this is not an eczematous process.
