Brightening and renewal serum with a 3-fold complex of vitamin C action (activity equivalent to 10% pure vitamin C) for high stability and maximum performance of the vitamin. The first source of vitamin C is derived from ascorbic ester which releases 100% active ascorbic acid into the skin upon application of the serum, the second is derived from a powerful peptide 5 times more active than natural vitamin C and the third source is the Kakadu plum, the plant with the highest percentages of vitamin C in the world. The serum offers a visible restoration of luminosity and improvement of skin discolorations, for a rested look, while at the same time it provides valuable antioxidant activity and strengthens 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.
