Reveal your skin's health with the La Roche-Posay Pure Vitamin C10, a radiance-revealing formula suitable for all skin types that will fight free radical damage & add vitality to the complexion. 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 & tobacco smoke. Created to address this issue, & specifically formulated to be suitable for use on sensitive skin, Pure Vitamin C10 is the first serum formulated at a physiological p H of 5.5 which offers the best tolerance for sensitive skin & helps to preserve the skin's barrier function. Enriched with 10% pure vitamin C, otherwise known as ascorbic acid, this biologically active form of vitamin C will brighten, stimulate collagen production & reduce the damage of free radicals. The inclusion of 0.45% salicylic acid will smooth & exfoliate away dead skin cells, while a duo of neurosensine & La Roche-Posay's own thermal spring water will eliminate inflammation, soothe redness & relieve sensitivity. Why We Love It With regular use, Pure Vitamin C10 will reveal a younger-looking complexion, diminishing fine lines & wrinkles & 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.
