What it is
An extract from the dried root of Pinellia ternata, a perennial herb native to East Asia. It contains alkaloids, saponins, and other bioactive compounds.
How it works
The extract is believed to reduce skin inflammation by inhibiting certain pro-inflammatory enzymes and cytokines. It may also have mild antioxidant effects, helping to protect skin from environmental stress.
