The new Aqua complex in Guerlain's Super Aqua Serum acts as a double protective shield. It reinforces the skin's internal barrier, increasing its reserves of moisture and increasing cellular resistance to time and external factors. It protects against aging and aggressions. Skin is deeply hydrated, re-plumped, smooth, supple and radiant. A legendary, deeply hydrating serum that revitalizes the skin and smoothes out wrinkles. 1.6 oz.
