what causes rosacea breakouts
Rosacea is not caused by alcohol abuse, as people thought in the past. But in people who have rosacea, drinking alcohol may cause symptoms to get worse (flare). Rosacea often flares when something causes the blood vessels in the face to expand, which causes redness. Things that cause a flare-up are called triggers.n rare cases, rosacea that is not treated may cause permanent effects, such as thickening of the skin on your face or loss of vision. It may cause knobby bumps on the nose, called rhinophyma (say ry-no-FY-muh). Over time, it can give the nose a swollen, waxy look.
