Mechanism of action

Brimonidine selectively binds to alpha-2 adrenergic receptors on vascular smooth muscle cells, causing vasoconstriction that reduces blood flow to the skin surface. This topical gel formulation is applied directly to facial erythema (redness), where it decreases visible flushing and persistent redness by narrowing capillaries in the affected areas. The effect is temporary and localized to the application site.
