The Chemistry Behind the Combination

Tetrahexyldecyl ascorbate (often abbreviated as THD Ascorbate or THDC) is a stable, oil-soluble form of vitamin C. Unlike traditional L-ascorbic acid, which can be unstable and irritating, THD Ascorbate is a stable vitamin C ester derivative. This makes it ideal for those who are new to vitamin C or for individuals with sensitive skin who want to target hyperpigmentation and support a brighter complexion.
