What it is
Bis-Glyceryl Ascorbate is a derivative of vitamin C designed to be more stable than pure ascorbic acid, which is prone to oxidation and degradation. By linking ascorbate to glyceryl groups, it offers antioxidant and conditioning benefits in a form that is easier to formulate and store. It is used in serums and sunscreens, including vitamin C oriented products, as a supporting antioxidant.
Safety & warnings
Vitamin C derivatives such as Bis-Glyceryl Ascorbate are generally better tolerated than high-strength pure ascorbic acid, with a lower tendency to cause stinging or irritation at typical use levels. It is water-compatible and not considered comedogenic.
Origin & sourcing
Synthetic; produced by chemically combining ascorbic acid (vitamin C) with glyceryl groups to create a more stable derivative.
Questions everyone asks
Is Bis-Glyceryl Ascorbate a form of vitamin C?
Yes. It is a stabilized vitamin C derivative made by attaching ascorbate to glyceryl groups for better stability than pure vitamin C.
Why use a vitamin C derivative instead of pure vitamin C?
Derivatives are more stable and less prone to oxidation, and they tend to be gentler, which makes them easier to formulate and often better tolerated.
