Rosacea

Definition

Rosacea is a chronic, inflammatory skin condition that primarily affects the central face — cheeks, nose, chin, and forehead — causing persistent redness, visible blood vessels (telangiectasia), and sometimes acne-like bumps and pustules. There are four subtypes: erythematotelangiectatic (redness and visible blood vessels), papulopustular (redness with bumps and pimples), phymatous (skin thickening, especially on the nose), and ocular (affecting the eyes). Rosacea affects an estimated 16 million Americans and is more common in fair-skinned individuals, though it can occur in all skin types. Common triggers include sun exposure, heat, spicy foods, alcohol, stress, certain skincare ingredients, and temperature extremes. While there is no cure, treatments include prescription topicals (metronidazole, azelaic acid, ivermectin), oral antibiotics, laser therapy for blood vessels, and a gentle skincare routine that avoids known triggers.
