Sérum Erythros is a cocktail of seven active ingredients that target the visible signs of rosacea. They combine to act synergistically on three complementary fronts to reduce visible areas of redness, make broken veins less apparent on the skin surface, and soothe any tingling sensations. Couperosis, also referred to as rosacea, is a skin disease which takes the form of redness primarily affecting the nose, cheeks, forehead and chin. The most common is erythematotelangiectatic rosacea, defined by vascularization disorders associated with cutaneous inflammation. It manifests itself in redness and visible blood vessels in the form of a spider’s web.
