What is rosacea, and how is it different from acne?

Rosacea most often affects the cheeks, nose, forehead, and chin. Common signs include flushing, redness that lasts, visible small blood vessels, and bumps that may contain pus. Some people also notice warmth, burning, stinging, or dry skin. On darker skin tones, redness may be harder to see, so warmth and skin sensitivity can be important clues.

Rosacea is not caused by poor hygiene and is not contagious. It differs from acne because blackheads and whiteheads are usually absent. Still, a person can have both conditions at once. Rashes, skin irritation, and other health problems can also look like rosacea.

A licensed physician in your state can review your health history, symptoms, and clear photos or a video visit. An in-person exam may be needed if the diagnosis is unclear. Treatment depends on which symptoms you have. It may help manage redness or bumps, but it does not cure rosacea. Results vary. Tell your physician about eye symptoms, too, because rosacea can affect the eyes.
