What it is
Yomogi extract is a water or alcohol-based extract from the leaves of Artemisia princeps, a perennial herb native to East Asia. It contains bioactive compounds like flavonoids, phenolic acids, and essential oils that contribute to its anti-inflammatory and antioxidant effects.
How it works
In a cosmetic product, yomogi extract works by delivering antioxidants that neutralize free radicals, which can cause premature aging. Its anti-inflammatory compounds help calm skin irritation and reduce visible redness. It also supports the skin's natural barrier function by promoting hydration and soothing sensitivity.
