Houttuynia Cordata extract is a plant-derived ingredient valued in skincare for its antioxidant, anti-inflammatory, and antimicrobial properties, often used to calm irritated, acne-prone, or sensitive skin. It contains flavonoids and polyphenols such as quercetin that help reduce redness and support the skin barrier.
