Bis-Glyceryl Ascorbate

Bis-Glyceryl AscorbateAntioxidant

A form of vitamin C joined to glycerin, used as an antioxidant and to hold water. Little research shows how well it works on skin.

What it does

Each vitamin C molecule carries two glycerin pieces. Drop hasn’t found a controlled study of it on skin.

The EU’s ingredient database lists it as an antioxidant (slows reactions with oxygen, like going rancid) and a humectant (helps hold in moisture).European Commission, CosIng (© European Union, CC BY 4.0) · uses put in plain words by Drop ↗
