The key ingredient NAC Y²™️, evolved out of Dr. Yannis’ collaboration with European biochemical engineers testing an ingredient called NAC on astronauts in Space, an extreme environment where skin ages more rapidly. The results were astounding.
This revolutionary ingredient complex is scientifically proven to promote glutathione production and encourage cellular renewal to visibly repair the skin and target the signs of premature ageing.
Dr. Yannis used this complex to develop his first ever formula, the Dramatic Healing Serum, the forerunner to our Y Theorem Repair Serum NAC Y²™.
The NAC Y²™️ complex is at the heart of all of the products in the Reparative collection.
Stimulates effectiveness of the most powerful intracellular antioxidant: Glutathione along with two additional ingredients: Escin which boosts circulation and oxygen capacity which are essential for healing and Vitamin C, an antioxidant vital for creating collagen
A potent antioxidant vital for synthesising collagen in the skin. It also works on pigmentation, fights free radicals and repairs and protects against UV damage.
A potent botanical tyrosinase inhibitor that brightens, tones and reduces hyperpigmentation.
After cleansing, distribute 1-2 pumps between your fingertips and apply to your face and neck in an upward motion.
