Efficacy, side effects and special precautions of Ascorbyl Tetraisopalmitate

Ascorbyl Tetraisopalmitate is a derivative of Vitamin C (ascorbic acid) commonly used in skincare products. It is an ester formed by combining ascorbic acid with isopalmitic acid. Here are some key points regarding its efficacy, side effects, and special precautions:


Ascorbyl Tetraisopalmitate is believed to have similar benefits to Vitamin C, which includes antioxidant properties. Antioxidants help protect the skin from damage caused by free radicals, which can contribute to aging and skin damage.

It may also assist in brightening the skin tone and reducing the appearance of hyperpigmentation.

Unlike pure ascorbic acid, Ascorbyl Tetraisopalmitate is considered more stable and less prone to oxidation, making it potentially more suitable for cosmetic formulations.
