first, it ‘s stability is only similar to that of pure ascorbic acid ( AA ), which means it is not actually stable. A great study in the Journal of Cosmetic Dermatology compared a crowd of vitamin C derivatives and this derivative instrument was the only one where the learn said in terms of constancy that it ‘s “ similar to AA ”. not truly that good .
Second, a study that examined the skin assimilation of vitamin C found that ascorbyl palmitate did not increase the skin levels of AA. This does not mean that ascorbyl palmitate can not penetrate the skin ( because it can, it ‘s anoint soluble and the clamber likes to absorb oil soluble things ) but this means that it’s questionable if ascorbyl palmitate can be converted into pure Vit C in the skin. even if it can be converted, the palmitate part of the molecule is more than the half of it, so the efficacy will not be good and we have never seen a serum that contains a decent ( and proudly disclosed ) amount of AP. We are highly doubting what effect a bantam come of AP has in a formula .
Third, another study that wanted to examine the antioxidant properties of AP was surprised to find that even though AP does have nice antioxidant properties; following UVB radiation ( the lapp one that comes from the sun ) it besides promotes lipid peroxidation and cytotoxicity. It was only an in-vitro report mean that it was done on cell cultures and not on real people, but still, this besides does not support the use of AP besides much.
The entirely well thing we can write about Ascorbyl Palmitate is that there is an in-vitro ( made in the lab, not on real people ) study showing that it might be able to promote collagen production .
Regarding the skin-brightening properties of pure vitamin C, this is another magic trick property AP does not have, or at least there is no data, not even in-vitro, about it .
Overall, Ascorbyl Palmitate is our least favorite vitamin C derivative. It is there in lots of products in bantam amounts ( honestly, we do not truly understand why ), however, we do not know about any vitamin C serum featuring AP in high amounts. That is credibly no concurrence. If you are into vitamin C, you can take a count at more bright derivatives here .
