Products with Tetrahexyldecyl Ascorbate
Tetrahexyldecyl ascorbate is an oil-soluble vitamin C derivative used where straight L-ascorbic acid would be too unstable or too irritating.
The Oil-Soluble Route to Vitamin C
Pure L-ascorbic acid is potent but temperamental — it needs a low pH, oxidizes quickly, and can sting. Tetrahexyldecyl ascorbate, often shortened to THD ascorbate, takes a different route: it is lipid-soluble, stable at neutral pH, and converts to ascorbic acid after it penetrates. That makes it a natural fit for creams, eye products, and formulas aimed at skin that cannot tolerate a traditional vitamin C serum, with the same remit of a brighter, more even-looking tone.
You will find it in the Revision Skincare C+ Correcting Complex, EltaMD UV Restore Broad-Spectrum SPF 40, Revision Skincare CMT Post-Procedure Cream, and Revision Skincare BodiContour.
Is THD ascorbate stronger than L-ascorbic acid?
Not stronger — different. It trades peak potency for stability and comfort, which often makes it the more practical choice for daily use.
How to shop at ELLEMES
Vitamin C formulas are the ones most worth buying from an authorized retailer, since age and heat degrade them faster than most categories.
