What it is: Stabilized vitamin C (3-O-ethyl ascorbic acid) is more stable than pure vitamin C and is not degraded by light or heat. Due to its excellent penetration properties, it is very well absorbed by skin and then converted in L-ascorbic acid. Vitamin C is a perfect radical scavenger sustainably protecting skin against the harmful influences of free radicals and thus preventing the premature, environmentally-induced skin aging. It balances the sensitive skin condition, strengthens skin's tissue, diminishes light irritations and redness, imparts more radiance and helps to gradually lighten pigment spots. By gently stimulating skin's collagen formation, fine lines and wrinkles are diminished. The result is a visibly more balanced, plump, firm and radiant skin.
