Summary

Antioxidant Soothing Humectant Anti-inflammatory Antimicrobial Sebum-regulating Skin Regeneration Barrier Support

Science

Mechanism of Action

The efficacy of Houttuynia Cordata Extract is primarily attributed to its high concentration of polyphenolic flavonoids, such as quercetin, quercitrin, hyperoside, and rutin. These compounds provide robust anti-inflammatory, antioxidant, and antibacterial actions by inhibiting inflammatory markers like prostaglandin E2, histamine, and nitric oxide. Additionally, its polysaccharide content functions as a humectant, enhancing skin hydration. It actively reduces irritation, calms redness, regulates excessive sebum production, combats acne-causing bacteria like *Cutibacterium acnes*, and supports skin regeneration, barrier function, and protection against environmental stressors.
