Stay-C® 50*: This molecule, obtained by binding pure L-ascorbic acid and Ascorbyl Sodium Phosphate, is a very stable form of vitamin C. Registered as a quasi-drug in Japan, it meets the needs of most skin. Clinical tests on a 3D skin sample and in vivo studies have fully demonstrated its effective brightening effect on the skin.
In topical use, vitamin C is of real benefit to the skin. Recognized as an antioxidant, it illuminates the complexion and reduces the signs of age. Vitamin C tones the skin when used over a prolonged period.
Water soluble in its pure form, it is more stable in the form of a powder, but then the pleasure of the cosmetic ritual is lessened. Here we offer a formula combining pure L-ascorbic acid – the most active, yet least stable form of vitamin C – together with an ascorbic acid salt form, which greatly contributes to better stability in the very high concentration.
