Rosacea, a common skin condition, presents with facial redness, visible vessels, and bumps. Current research explores its subtypes and potential causes like vascular issues, environmental factors, and microbes.

Area of Science:

  • Dermatology
  • Pathogenesis of skin conditions

Background:

  • Rosacea is a prevalent dermatological condition affecting the central face.
  • It manifests as erythema, telangiectasias, papules, and pustules.
  • The condition is classified into four subtypes: erythematotelangiectatic, papulopustular, phymatous, and ocular.

Discussion:

  • The etiology of rosacea is not fully understood.
  • Hypotheses include vascular abnormalities, dermal matrix degeneration, and environmental triggers.
  • Microorganisms like Demodex folliculorum and Helicobacter pylori are also investigated as potential contributors.

Key Insights:

  • This review focuses on the updated classification of rosacea subtypes.
  • It highlights the primary theories regarding the pathogenesis of rosacea.
