A water-light eye serum built on a 7.5% concentration of L-Ascorbic Acid, the free-acid form of vitamin C, at a strength intended for the eye area. The list is short: water, sodium hyaluronate, ascorbic acid, zinc sulfate, tripeptide-1, bioflavonoids and mushroom extract. Ten ingredients in total, no oils and no silicones. It absorbs immediately and can tingle briefly on the first few uses.

For dull, shadowed under-eyes and fine crepey lines, and for anyone who wants antioxidant support close to the eye. One to two drops in the morning, on clean skin, before eye cream. Free-acid vitamin C oxidizes, so keep it capped and away from light and replace it if it turns amber. Hold off if your eye area is currently reactive.
