After inserting a pure-collagen sponge soaked in NAC under the skin of a surgical patient to accelerate healing, Dr Yannis elevated the formula for his non-surgical patients. From there, NAC Y² was born, a complex that includes a trio of actives with superior antioxidant capabilities, one of which stimulates the production of Glutathione – the body’s most powerful intracellular antioxidant. The superior results included epidermal strengthening, scar reduction and a more youthful appearance. 

Used as the core of every product in the Reparative range and included in several other ranges, NAC Y² has come to embody the principal of 111SKIN - innovative science that yields unrivalled results.
