There are many theories but none have been proven. See your dermatologist. It is easy to mistake skin disorders and doctors know best how to identify and treat rosacea. Non-prescription acne medications may irritate dry, sensitive skin. These products may have ingredients that are not appropriate for treating rosacea.
Treatment can lessen or get rid of symptoms.
Several medications are available by doctor's prescription. They control redness and reduce the number of papules and pustules. Once symptoms have cleared, patients may need to continue taking medication to keep rosacea under control. Controlling the causes of flushing and blushing can help prevent rosacea from getting worse and blood vessels from getting larger. But once red lines appear, they can only be covered up by makeup or removed by a surgical method.
