What it is
A finely ground powder from the dried leaves of Houttuynia cordata, a perennial herb native to East Asia. It contains flavonoids, quercetin, and other bioactive compounds known for anti-inflammatory and antimicrobial effects.
How it works
When applied to the skin, the powder's compounds help reduce inflammation by calming immune responses in skin cells. Its antioxidants neutralize free radicals, which can otherwise damage collagen and lead to premature aging. Some studies also suggest it can inhibit certain acne-causing bacteria.
Pros
