Ascorbyl Tetraisopalmitate · Tetrahexyldecyl AscorbateAntioxidant
The oil-soluble vitamin C. It’s stable and turns active on skin. Common in pricier serums for sensitive skin.
What it does
It’s the most oil-friendly form of vitamin C, so it works in oil-based, water-free serums. It’s stable, and your skin turns it into the active form at a useful rate. It’s common in pricier vitamin C serums sold for sensitive skin.
The EU’s ingredient database lists it as an antioxidant (slows reactions with oxygen, like going rancid) and an emollient (gives skin a soft, smooth look).European Commission, CosIng (© European Union, CC BY 4.0) · uses put in plain words by Drop ↗
