General information

  • Chronic or recurrent inflammatory facial dermatosis characterized by a papulopustular eruption.
  • Primarily affects young to middle-aged women (20–45 years), although children and men may also be affected.
  • Predominantly involves the perioral, perinasal, and periocular regions.
  • Topical corticosteroids +++ are the strongest recognized association; rebound flaring may occur after withdrawal. Inhaled and intranasal corticosteroids may also contribute.
  • Other associated triggers include cosmetics, occlusive facial products, sunscreens, toothpaste/dental irritants, heat, wind, and UV exposure.
  • Epidermal barrier dysfunction and inflammation appear to contribute to pathogenesis.

Symptoms / presentation

  • Gradual eruption of small facial papules and pustules.
  • Burning, stinging, or tightness may occur.
  • Pruritus is usually mild or absent.
  • Skin may feel dry and sensitive.
  • Patients are generally systemically well.

Clinical exam

  • Monomorphic 1 to 2 mm erythematous papules, sometimes papulovesicles or pustules.
  • Clustered on an erythematous background and may become confluent.
  • Fine scaling and dryness may occur.
  • No comedones +++, helping distinguish it from acne vulgaris.
  • Characteristic sparing of the skin immediately adjacent to the vermilion border +++, although this is not invariably present.

Distribution

  • Perioral +++
  • Nasolabial and perinasal areas
  • Periocular area
  • Chin
  • More severe disease may extend onto the cheeks, eyelids, forehead, and glabella

Dermoscopy

  • Erythematous background.
  • Fine dotted and linear vessels, irregularly distributed.
  • Fine white scaling may be present.
  • Pustules and follicular structures may be visible.
  • Nonspecific findings; dermoscopy is mainly an adjunct to clinical diagnosis.

Diagnosis

  • Primarily a clinical diagnosis.
  • No investigations are generally required for typical disease.
  • Culture ± KOH preparation when bacterial or fungal infection is suspected.
  • Patch testing when allergic contact dermatitis is suspected.
  • Biopsy is rarely required and is reserved for atypical or treatment-resistant presentations.

Differential diagnosis

Treatment plan

  • Begin with “zero therapy”: minimize facial products, particularly cosmetics and occlusive preparations. This alone may resolve mild disease.
  • Discontinue facial topical corticosteroids. Gradual tapering may be appropriate after prolonged/potent steroid exposure because abrupt withdrawal can produce a rebound flare. Do not restart the steroid because of the rebound.
  • Medically necessary inhaled or intranasal corticosteroids should not simply be discontinued; rinsing the face and mouth after use may reduce cutaneous exposure.
  • Mild/localized disease: topical metronidazole 0.75-1%, topical erythromycin, or pimecrolimus 1% BID, typically for several weeks.
  • Pimecrolimus may be particularly useful in corticosteroid-associated disease.
  • Moderate-to-severe, extensive, or refractory disease: an oral tetracycline, commonly doxycycline, generally for approximately 4-8 weeks, with duration individualized according to response.
  • Doxycycline is used primarily for its anti-inflammatory activity; adverse effects include photosensitivity, gastrointestinal upset, and pill esophagitis.
  • Avoid an automatic prolonged high-dose doxycycline → maintenance-dose regimen for every patient; treatment intensity and duration should be individualized, particularly because the overall evidence base for periorificial dermatitis therapy remains limited.
  • When tetracyclines are unsuitable, such as during pregnancy or in young children, erythromycin may be considered depending on the clinical context.
