Dr. Renaud C 10% Vitamin Serum with M2PE Technology neutralizes the sources of UV-induced damage in all the layers of the skin. By combining vitamin C - a powerful antioxidant in its purest form, L-ascorbic acid USP 10% - with exclusive M2PE technology, the absorption of the serum is multiplied and its action is optimized for a visibly more youthful and firmer appearance.
How to use: Apply the serum twice a day, morning and night, on cleansed and dry skin. Use a few drops where desired (face, neck, décolleté) and massage in with little effleurages. Follow up with your usual day or night cream. In the daytime, also apply a sun product with an SPF at least 30.
