111SKIN's Repair Serum was originally created by Dr. Yannis Alexandrides to help heal his patients' skin post-surgery and is now available for all. The formula, no longer exclusive to Harley Street clients, is powered by the brand's nac Y² Triple-Encapsulation Repair Technology, delivering actives deeper into the epidermis for improved elasticity and reinforced skin barrier function. On application, the cooling, velvety texture absorbs quickly into the skin, leaving it instantly softer, nourished and hydrated.
