NAC Y²™
111SKIN’s proprietary complex; designed to repair, soothe, and protect skin by promoting the production of glutathione – the body’s master antioxidant. It also helps to support healthy collagen production and improve elasticity. The innovative formula is now encapsulated to allow for four times the reparative power, deeper delivery, and enhanced efficacy.

NAC Y²™ BREAKDOWN
NAC: An advanced amino-acid with superior reparative properties. It triggers the production of glutathione to help provide advanced protection against free radical damage, preserve skin, and slow the ageing process. Thanks to advanced encapsulation technology, the new, ground-breaking formula boasts four times more NAC – the highest clinically-tested level – to supercharge benefits and yield truly transformative results.
Escin: This new-generation active, known for its anti-inflammatory benefits, has always been a key component of NAC Y²™, found in the form of Horse Chestnut Extract. To augment its benefits, Dr Yannis has added an upgraded, more concentrated form of Escin to the complex. This allows it to work as a dual-layered system for enhanced results.
Vitamin C: The cornerstone of many skincare formulas thanks to its antioxidant benefits. By combining it with NAC, we’re pushing its potential one step further. While NAC triggers the production of glutathione, Vitamin C sustains it to ensure the external and internal benefits last as long as possible.
