A fat-soluble vitamin C ester, mainly used as an antioxidant preservative.
This ingredient also helps blend vitamins A, C & D into a suspension. It’s an effective collagen builder and free-radical scavenging ingredient. Because it’s fat-soluble, it can penetrate the skin and deliver antioxidants faster than the water soluble forms of Vitamin C. This helps prevent cellular aging by inhibiting the cross-linking of collagen, oxidation of proteins, and lipid peroxidation.
Ascorbyl palmitate is particulatly effective at reducing free radicals generated from UVB rays and, due to its palmitate portion, is also a moisturizing form of vitamin C.
Furthermore, it’s been shown to work together with Vitamin E. Studies have also show it to be more stable than L-ascorbic acid.
As a preservative, it’s mainly used in makeup products, but recent discovery of its superior antioxidant properties has helped it become an active ingredient in a variety of skincare products such as suncreens, lotions/crèmes, anti-aging treatments and serums.
