Rosacea is a long-term skin condition that primarily affects the face of fair-skinned people, causing episodes of flushing. Various things may trigger an episode, including sunlight, caffeine, alcohol, spicy foods, and stress.
Eventually, there may be persistent facial redness, visible blood vessels in the skin (telangiectasia), pimples and pustules, and thickening of the skin; the nose may also become bulbous (rhinophyma).
Treatment includes avoiding triggers, and antibiotics or other prescribed medications to clear up severe pimples. Telangiectasia may be treated with laser therapy
