About

Extract from Alpine rose flowers — a hardy mountain plant with antioxidant and skin-protecting properties. Used in anti-aging formulas targeting environmental stress.

Rhododendron Ferrugineum Flower Extract (CAS 90106-21-1) is derived from the flowers of the rusty-leaved alpenrose (Ericaceae), a shrub native to European alpine regions. The plant produces secondary metabolites including flavonoids, phenolic acids, and terpenoids that help it survive harsh UV and cold conditions. In cosmetics, these compounds translate to antioxidant and photoprotective benefits. Some Rhododendron species contain grayanotoxins, which are toxic diterpenes, though R. ferrugineum has lower levels. Limited specific cosmetic safety data exists for this species.
