Inspired by Dr Yannis’ in-clinic treatments, the 111SKIN Black Diamond Vitamin-C Booster Serum visibly brightens and refreshes tired, dull-looking skin. Powered by 3% vitamin C, the formula lends potent antioxidant defence to protect against urban pollutants and environmental stressors, reducing the appearance of discolouration. 3% Resurrection plant extract and niacinamide supports the booster serum by visibly smoothing and firming the skin, while minimising the appearance of dark spots, pigmentation and uneven tone.
