Eye Lift Gel NAC Y2 15 ml This product helps promote the production of glutathione - the body's most important antioxidant - and protects against free radical damage. Formulated to visibly reduce fine lines and dark circles while lifting and refining the under-eye area. 111SKIN's signature complex also helps to improve elasticity, leaving skin firmer and smoother. The addition of argireline helps to lift and shape the under-eye area and minimise the appearance of fine lines, while our bi-functional caffeine complex fights signs of fatigue.
