What it is
A natural extract obtained from the dried rhizome (underground stem) of the Iris Germanica plant, also known as orris root. It contains compounds like isoflavonoids, triterpenoids, and essential oils that contribute to its skincare properties.
How it works
In a cosmetic product, Iris Germanica Root Extract works primarily as a soothing agent by potentially reducing the release of pro-inflammatory signals in the skin. Its antioxidant compounds may help neutralize free radicals, which are unstable molecules that can damage skin cells and accelerate aging. It also provides a subtle, pleasant floral scent in some formulations.
