The only difference between the old and new version of our Vitamin C product is that the new version does not contain the ingredient, Caffeine. It is otherwise the same ingredients, concentration, and form of Vitamin C. 

The ingredient caffeine supposedly is good for capillary restrictions, ie. redness reduction which would only be temporary. Caffeine has become very hard to source, as there is a worldwide shortage. We also had people confused by the ingredient as caffeine can be perceived negatively by pregnant women for example. So for those reasons, we took it out.
