The Rose Gold Brightening Facial Treatment Mask by 111Skin is the brand’s claim to Instagram fame but it was the Y Theorem Repair Serum that firmly established its name in the beauty industry. Initially created to heal a patient’s skin after surgery, the serum showed extraordinary anti-aging benefits that made it a phenomenon. Behind the success of these hero products is Dr Yannis’ 30+ years of experience combined with science-led ingredients. Today the UK-based brand continues to innovate by offering groundbreaking formulations that press pause on aging. The newly launched advanced NAC Y²™ is seen in the reparative collection featuring Repair Serum, Repair Day Cream, Y Theorem Repair Light Serum and Bright Eye Lift Gell — all available in our Kuwait edit below. Some of the other creations that are loved by fans include 3 Phase Anti Blemish Booster, Antioxidant Energising Essence, Celestial Black Diamond Serum and The Firming Concentrate set.
