Understanding rosacea<\/span><\/h2>\n

Rosacea<\/span><\/a> is a skin condition that affects the blood vessels of the face. It\u2019s a chronic inflammatory disease that tends to come and go over time. Rosacea causes long-term redness (erythema), enlarged blood vessels, and lesions on the skin, which could lead to scarring and ocular rosacea, which affects the eyes.<\/span><\/p>\n

In order to get the right treatment, healthcare providers diagnose rosacea clinically by ruling out other conditions. \u201cThere is no specific test to diagnose rosacea. Instead, a dermatologist will review a patient\u2019s signs and symptoms along with their medical history,\u201d says <\/span>Long Ly<\/span><\/a>, MD, board-certified dermatologist at MetroDerm in Atlanta, Georgia. \u201cBecause rosacea can resemble other conditions, your doctor may consider things like acne, seborrheic dermatitis, contact dermatitis, or perioral dermatitis. These have similar symptoms, but also important differences. For example, acne often involves blackheads and whiteheads, while rosacea does not,\u201d Dr. Ly adds.<\/span><\/p>\n

For people with rosacea, the body\u2019s <\/span>immune system<\/span><\/a> is activated, causing inflammation in the blood vessels of the face. This leads to the symptoms of rosacea, discussed below. It\u2019s not clear what exactly causes rosacea, but there are risk factors for developing the condition:<\/span><\/p>\n
