What is Vitamin C Ester? - Frequently Asked Questions (FAQs) - Dr. Perricone

I have Ester C and Vitamin C products -- are they the same as Vitamin C Ester?
Topical Vitamin C Ester (Ascorbyl Palmitate) is an agent that is not only water soluble, but also is fat-soluble. This allows for rapid penetration into all layers of the cells of your body for maximum results. This version is also much gentler to the skin and more stable in topical compositions retaining it's efficacy and active ingredients for around 2 years rather than 2 months. The Vitamin C and Ester Cs that you can buy in a drug store or vitamins shop or health food store are generally a form of L-Ascorbic Acid that is only water soluble, more irritating to the skin, and is much less stable, leading to a much shorter shelf life.
