Oil-soluble vitamin C derivative. Stable in oil-based formulations; conversion to active vitamin C is modest.
What it does
Ascorbyl palmitate is a single-palmitic-acid-tail vitamin C derivative — oil-soluble, stable in lipid formulations, but with a less impressive conversion-to-active rate than ascorbyl tetraisopalmitate. Often used as an antioxidant additive (preventing other oils from going rancid) more than as a primary brightening active. The functional skin effect is modest at typical use rates.
