Ascorbyl Tetraisopalmitate

What Ascorbyl Tetraisopalmitate is & what it does

A highly stable, oil-soluble vitamin C ester that penetrates deeply for antioxidant, brightening, and collagen-supporting benefits. It is gentle and long-lasting.

What does Ascorbyl Tetraisopalmitate do in skincare?

Ascorbyl Tetraisopalmitate is an oil-soluble derivative of vitamin C used as a skin-conditioning antioxidant. It is favored because it is more stable in oil phases than pure vitamin C and can penetrate oil-rich formulas well. It is commonly used to bring vitamin C benefits to creams and serums.

Is Ascorbyl Tetraisopalmitate natural or synthetic?

It is a synthetic, lab-made derivative of vitamin C combined with fatty acid groups to make it oil-soluble and stable. While it is based on a vitamin found in nature, the ingredient itself is produced through a manufacturing process. This is what gives it better stability than plain ascorbic acid.

Is Ascorbyl Tetraisopalmitate safe for skin?

Ascorbyl Tetraisopalmitate is widely used as a gentle, oil-soluble form of vitamin C and is generally well tolerated. As with any active, sensitivity can vary, so a patch test is sensible if your skin reacts easily. It is often chosen specifically because it tends to be less irritating than pure vitamin C.
