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

Gentle on sensitive skin

Unlike some stronger botanical extracts, Houttuynia cordata is very well-tolerated and unlikely to cause stinging or irritation, making it a safe choice for those with reactive skin.

Multi-functional benefits

It combines soothing and antioxidant actions in one ingredient, so it can help calm redness while also protecting skin from daily environmental stressors.

Cons and cautions

Limited clinical evidence

Most research on Houttuynia cordata is lab-based or on animals. There are few large human studies confirming its effectiveness in skincare products.

Variable potency
