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 same one that comes from the sun) it also promotes lipid peroxidation and cytotoxicity. We are highly skeptical what effect a tiny amount of AP has in a formula. 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.

This does not mean that ascorbyl palmitate cannot penetrate the skin (because it can, it's oil soluble and the skin 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. Second, a study that examined the skin absorption of vitamin C found that ascorbyl palmitate did not increase the skin levels of AA. A great study in the Journal of Cosmetic Dermatology compared a bunch of vitamin C derivatives and this derivative was the only one where the study said in terms of stability that it's "similar to AA".
Nice to spot on any ingredient list.įirstly, it's stability is only similar to that of pure ascorbic acid (AA), which means it is not really stable. Of course, it cannot make a miracle but it might have some effect via regulating microcirculation and normalizing the metabolism in the cells of connective tissues.īottom line: Gotu Kola is a great plant ingredient with proven wound healing, anti-inflammatory, and antioxidant properties. Asiaticoside was shown to increase antioxidant levels on rats skin when applied at 0.2%.Ĭentella Asiatica also often shows up in products that try to treat cellulite or striae. Madecassoside can also help in burn wound healing through increasing antioxidant activity and enhancing collagen synthesis. This is probably one of the reasons why Centella Asiatica Extract has nice skin moisturizing properties that was confirmed by a 25 people, four weeks study along with Centella's anti-inflammatory effects. One of the biological activities of the centellosides is to be able to stimulate GAGs (glycosaminoglycans - polysaccharides that are part of the liquidy stuff between our skin cells), and especially hyaluronic acid synthesis in our skin.
