Editor's Notes

111SKIN's 'Y Theorem Repair Serum' was the first product developed by Harley Street surgeon Dr Yannis Alexandrides. Designed to improve elasticity, boost collagen production and support cell regeneration, it's powered by the brand's potent NAC Y² formula - a patented blend containing key ingredients used by astronauts to protect their skin from ageing in zero-gravity conditions. Healing Aminocaproic Acid and soothing Calendula also reduce the appearance of scarring, so it's a good option if you've ever suffered from acne.


- Anti-aging serum - Gently pat into face and neck before moisturiser - Free from parabens, paraffins and silicone
