C+C Serum

A water-free vitamin C serum that pairs 10% L-ascorbic acid with 5% ascorbyl tetraisopalmitate in a smooth silicone base to brighten and protect against environmental damage. Because it's formulated without water, the vitamin C stays stable and potent for much longer than your average liquid serum. The velvety, primer-like texture makes it a great layer under sunscreen, though the silicone finish rewards a bit of patience during application.
