The ordinary Ascorbyl Glucoside Solution 12%

Ascorbyl Glucoside Solution 12% offers a lightweight, water-based formula that helps reduce signs of aging by brightening and balancing uneven skin tone. Unlike direct forms of vitamin C, this easy-to-use serum contains a water-soluble vitamin C derivative that converts into vitamin C once applied, giving it less irritation potential. And because it has advanced antioxidant properties, it also protects skin from the visual effects of damage caused by environmental stressors, helping to maintain a more radiant complexion.

Note: In its pure form, vitamin C is unstable in water. Ascorbyl Glucoside is a water-soluble derivative of vitamin C. It is much more stable in water but it is less potent than direct L-Ascorbic Acid.
