What It Does
Deep Dive
Native to East Asia, Houttuynia Cordata has been used in traditional Korean and Japanese medicine for centuries โ mostly as a tea for inflammation. Topically, it contains quercetin and quercitrin (polyphenol flavonoids) shown to reduce TNF-ฮฑ and inhibit the Malassezia-driven inflammation behind many fungal acne and rosacea flare-ups. Anua put it on the global map with a 77% concentrated toner in 2022; within two years it was the most-searched K-beauty ingredient on TikTok. Works on almost anyone โ it is that rare "first, do no harm" ingredient with actual mechanism.
