A hydration concentrate with natural-origin hyaluronic acid for plumper and more supple skin. Derived from natural-origin fermented wheat, the hyaluronic acid molecules in this serum have different molecular weights to both rehydrate skin on the surface and help restore the skin's plumpness. Enriched with antioxidant-boosting iris extract (in-vitro test on ingredients) and composed of 87% (values calculated on the basis of ISO standard 16128 part II and according to the raw ingredient data sent to date by Dior suppliers) natural-origin ingredients, this serum has a fresh, nourishing texture that leaves skin feeling smooth and plump.
