Skin ageing can be caused by many things. Genetic factors account to 30% of the ageing process due to the slow down of the metabolism of skin cells, with the remaining 70% is caused by exposure to external factors such as UV rays, pollution, infrared and tobacco smoke. Created to address this issue, and specifically formulated to be suitable for use on sensitive skin, Vitamin C is the first serum formulated at a physiological pH of 5.5 which offers the best tolerance for sensitive skin and helps to preserve the skin’s barrier function. Enriched with pure vitamin C, otherwise known as ascorbic acid, this biologically active form of vitamin C will brighten, stimulate collagen production and reduce the damage of free radicals. The inclusion of 0.45% salicylic acid will smooth and exfoliate away dead skin cells, soothe redness and relieve sensitivity. Why We Love It With regular use, Will reveal a younger-looking complexion, diminishing fine lines and wrinkles and encouraging a healthy vitality. Plus, thanks to it being housed within a bright orange UV filtered bottle, the active molecules within the serum will be protected from UV rays-induced degradation, so you can count on the long term stability of the formula. How To Use It Apply in the morning before your moisturiser. net chose: (10/15ml/20/40ml)
