What it is
An extract derived from the flowers and leaves of Houttuynia cordata, a perennial herb native to East Asia. It contains active compounds like flavonoids, quercetin, and polyphenols that contribute to its soothing and antioxidant effects.
How it works
The extract's flavonoids and polyphenols help neutralize free radicals that can damage skin cells. It also appears to reduce the production of inflammatory signals in the skin, which can help calm redness and irritation. Some research suggests it may support the skin barrier by reducing water loss.
Pros
