Rosacea is a long-term skin condition that typically affects the face.[2][3] It results in redness, pimples, swelling, and small and superficial dilated blood vessels.[2] Often, the nose, cheeks, forehead, and chin are most involved.[3] A red, enlarged nose may occur in severe disease, a condition known as rhinophyma.[3]
The cause of rosacea is unknown.[2] Risk factors are believed to include a family history of the condition.[3] Factors that may potentially worsen the condition include heat, exercise, sunlight, cold, spicy food, alcohol, menopause, psychological stress, or steroid cream on the face.[3] Diagnosis is based on symptoms.[2]
While not curable, treatment usually improves symptoms.[3] Treatment is typically with metronidazole, doxycycline, minocycline, or tetracycline.[4] When the eyes are affected, azithromycin eye drops may help.[5] Other treatments with tentative benefit include brimonidine cream, ivermectin cream, and isotretinoin.[4] Dermabrasion or laser surgery may also be used.[3] The use of sunscreen is typically recommended.[3]
Rosacea affects between 1% and 10% of people.[2] Those affected are most often 30 to 50 years old and female.[2] Fair-skinned people seem to be more commonly affected.[6] The condition was described in The Canterbury Tales in the 1300s, and possibly as early as the 200s BC by Theocritus.[7][8]
