The Methode Physiodermie Pure Vitamin C, i.e. in its L-Ascorbic Acid form – pH ≈ 3,5 Pure Vitamin C, i.e. in its L-Ascorbic Acid form, is acclaimed by skin care professionals for its clinically proven results. However, in contact with air, water or light, Vitamin C oxidizes very easily, thus losing its effectiveness. What makes the difference: To guarantee all its freshness and to free itself from the chemical solvents used by the cosmetic industry to improve its stability, Physiodermie conditioned the pure Vitamin C in the form of powder in a stick. This one is to be poured at the time of the opening in a serum containing hyaluronic acid. Once reconstituted, the serum is stable for at least 1 month, thus offering all the performance of pure Vitamin C concentrated at 15% for the duration of the treatment.
