This combination of lipid-soluble vitamin C, grape-derived polyphenols, and hydrators hyaluronic acid and squalene is a dream team of active ingredients.  In laboratory studies, this antioxidant blend blocked 100% of free radicals, and in clinical studies it resulted in dramatic improvement in skin quality in 1 month.  This cutting edge formulation sinks right into skin and doesn't rely on alcohol to keep the active ingredients stable, which is rare among antioxidant serums and makes for an exceedingly gentle but effective approach to anti-aging.
