Iris Florentina (orris) root extract is derived from the rhizome of the iris plant and is used in skincare primarily as a fragrance component and skin-conditioning agent, valued for its aromatic and emollient properties. It is sometimes claimed to have antioxidant and astringent effects, though clinical evidence is limited.
