Geranium Robertianum Extract is a plant-derived ingredient obtained from the herb Robert (Geranium robertianum), used in skincare for its antioxidant, astringent, and soothing properties attributed to tannins, flavonoids, and phenolic compounds. It is generally included as a conditioning and protective botanical additive rather than a clinically proven primary active.
