What are the benefits of using vitamin c in encapsulated delivery systems?
Vitamin C Actives are one of the best ingredients that we can use for anit-aging and anti-oxidant products keeping in mind that vitamin c is highly oxidative. This is no problem for the experienced cosmetic chemist who can stabilize the vitamin c and utilize its benefits in cosmetics, otherwise the result is an unstable product that will begin to show the signs of oxidation as the vitamin c becomes unstable and creates free radicals. Of course, in personal care one of the main goals is to address free radical activity. With an encapsulation the vitamin c is stabilized and the oxidation is no longer an issue. The added benefit is the delivery enhancement that you get with an encapsulation because the phospholipid used to encapsulate the active is a much smaller molecule which can penetrate the top, dead, layer of skin and deliver the active to the tissues where you can gain the benefits of the vitamin c rather than having them reside in the dead layers until they are eliminated.
