While general redness from irritation can be soothed with gentle moisturizers, the persistent facial redness (erythema) of rosacea is a vascular issue—meaning it is caused by dilated blood vessels under the skin. To reduce this quickly, you need a specialized prescription treatment that actively constricts those vessels. Mirvaso is a unique, fast-acting topical gel specifically designed for this purpose. When applied, it temporarily shrinks the dilated blood vessels, providing a rapid and dramatic reduction in facial redness for up to 12 hours.
