What it is

A water- or alcohol-based extract of the leaves of Artemisia princeps (Japanese mugwort), containing flavonoids, polyphenols, and essential oils that give it antioxidant and anti-inflammatory properties.

How it works

The extract's flavonoids and polyphenols help neutralize free radicals and reduce the production of pro-inflammatory molecules in skin cells, which can calm redness and irritation. It also supports the skin barrier by promoting hydration retention.

Pros
