The Ordinary L-Ascorbic Acid

100% L-ascorbic acid powder is a powdered form of pure vitamin C that visibly reduces signs of ageing by brightening and evening out skin tone and protecting your skin from environmental damage. As it is 100% vitamin C, it is designed to be mixed with other serums, creams or moisturisers in your skincare routine - allowing you to create a customised vitamin C treatment. Depending on your blend, your combination may contain a high concentration of direct vitamin C, so expect a very strong but non-irritating tingling sensation for the first 1-2 weeks of use until the skin has acclimatised to this high concentration.
