Shine and renewal serum with 3-fold vitamin C action complex (activity equivalent to 10% pure vitamin C) for high stability and maximum performance of the vitamin. The serum offers visible restoration of luminosity and improvement of skin discolorations, for a rested look, while at the same time providing valuable antioxidant activity and strengthening the skin's defense against endogenous and exogenous "attacks". Finally, it reduces the extent and depth of wrinkles, activating the synthesis of the skin's structural proteins and "waking up" its self-repair mechanisms.
