Caprylyl 2-Glyceryl Ascorbate

Caprylyl 2-glyceryl ascorbate is a derivative of vitamin C (ascorbic acid) modified with caprylyl and glyceryl groups. This chemical modification makes it more stable than pure ascorbic acid whilst retaining antioxidant activity. It functions as both an antioxidant and a humectant, meaning it helps protect skin from environmental damage and supports moisture retention.This ingredient is designed to be gentler and more stable than L-ascorbic acid, making it suitable for formulations where pure vitamin C would be prone to degradation. It does not require extremely low pH to be effective, whic…

The ingredient works through two mechanisms. First, as an antioxidant, it neutralises free radicals that would otherwise damage skin cells and contribute to visible ageing and inflammation. Second, as a humectant, it draws moisture into the skin and helps the outer layers retain it, supporting hydration.The glyceryl and caprylyl modifications allow this form of vitamin C to penetrate the skin more readily than some other stabilised derivatives, whilst remaining chemically stable at higher pH levels than pure ascorbic acid requires. This stability makes it easier to formulate into products w…

This ingredient is typically found in serums, moisturisers and targeted treatments. Use as directed on the product label. If introducing a vitamin C product to your routine, start with use 2–3 times per week and gradually increase frequency as tolerated. Apply to clean, dry skin before moisturiser. Store products in a cool place away from direct sunlight to maintain stability. Because it is less prone to oxidation than L-ascorbic acid, you may notice less browning of the product over time, which is a sign of stability.

Generally well-tolerated across skin types. Some individuals may experience mild irritation or sensitivity, particularly if skin is already compromised. Patch testing is recommended, especially for sensitive skin.
