NAC Y2™
111SKIN’s signature complex helps promote the production of glutathione – the body’s master antioxidant – while protecting against free radical damage. It supports healthy collagen production and improves elasticity for firmer, smoother skin.
The Origins of NAC Y2™:
A Surgeon’s Vision
When world-renowned surgeon Dr. Yannis Alexandrides set out to create a topical formula, his goal wasn’t to launch a skincare brand—it was to protect and prepare patients’ skin before and after surgery.
At the time, most products were too harsh for sensitized skin. Drawing on decades of clinical experience, Dr. Yannis turned to NAC (N-Acetyl Cysteine), a compound trusted in medicine and even studied for shielding astronauts from oxidative stress.
To boost its effects, he paired NAC with:
- Vitamin C – Preserves NAC’s potency while brightening and defending skin.
- Escin – Reduces inflammation and supports oxygen delivery.
Together, these ingredients form NAC Y2™, a pioneering complex that helps repair, protect, and rejuvenate skin against daily stressors.
What NAC Y2™ Does for Your Skin
NAC Y2™ is more than just another anti-ageing ingredient—it’s a clinically proven complex designed to repair, rejuvenate, and protect skin from daily stressors.

The Product That Started It All:
The Repair Serum
Launched in 2012, the Repair Serum NAC Y2™ was the first 111SKIN product to introduce this pioneering complex, born as an evolution of the Healing Serum, originally created by Dr. Yannis for his clinical patients. The remarkable results seen in the clinic quickly led to wider demand, establishing Repair Serum NAC Y2™ as the brand’s first hero formula.
More than a decade later, it remains 111SKIN’s most iconic product.
