This is a Beyond Beauty product which means it has been sourced, tried and tested and finally declared one of the most new and innovative heroes out there. The skin-refining serum that helps to repair, plump, and protect your complexion. Powered by 111SKIN's new NAC Y² Triple-Encapsulation Repair Technology, this antioxidant-rich formula encourages skin repair to help optimise the appearance and reinforce the skin barrier for up to 48 hours. Over time, this serum helps to repair and rebalance your complexion by triggering production of glutathione - the body's master antioxidant - and reducing redness. Originally created by Dr Yannis Alexandrides to help heal his patients' skin post-surgery, the Repair Serum NAC Y² is now stocked across the globe by the world's most prestigious retailers. This exclusive formula, once only available to Harley Street clients, has found its way into the skincare routines of dermatologists, aestheticians, and beauty editors. It's time it took its place in yours.
