Discover our first antioxidant serum formulated with 15% pure vitamin C (L-ascorbic acid), one of the most effective ways to treat and correct the key signs of skin aging, helping to protect it from oxidative stress, reduce dark spots, improve radiance and soften expression lines. Its formula also contains 5% Glutathione, a powerful antioxidant that reinforces the brightening action and helps fight oxidative damage, as well as 1% Green Tea Extract, known for its soothing and protective properties against free radicals. Ideal for those looking for an advanced solution with pure vitamin C. However, if you have sensitive skin, we do not recommend Ascorbic C15 due to its low pH. Instead, you can opt for other options with vitamin C derivatives such as Super C or Tetramid C.E.F With 15% pure vitamin C to brighten the skin and even out tone. With Glutathione and Green Tea Extract for complete antioxidant action and to soothe the skin. Light, watery texture that is quickly absorbed. Pure Vitamin C is very unstable and difficult to formulate, and although the formula uses a low pH and additional antioxidants to stabilise the Vitamin C, Ascorbic C15 has a PAO of 3 months. Once opened, store in a cool dry place below 5º once opened.
