Vitamin C Suspension 23% + HA Spheres 2%

Vitamin C Suspension 23% in HA Spheres uses direct vitamin C and hyaluronic acid to help visibly reduce signs of aging by brightening and balancing uneven skin tone. This water-free formula provides 23% pure L-Ascorbic Acid which remains completely stable due to the absence of water. What’s more, this water-free formula is supported with spheres of hyaluronic acid for added hydration. Note: The slightly granular texture of this product is due to the vitamin C powder being suspended in an oil-like base and therefore each application requires a few seconds to feel absorbed by the skin. If desired, this formula can be diluted in a cream base per application to allow the skin to build tolerance over time.” with “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.
