Is Vitamin C also a pro-oxidant?

Hi! I am seeing raves about topical vitamin C as an excellent antioxidant for skin. However, without being an expert, and if I am even making sense, what happens to vitamin C after it donates to a free radical/ros? I am definitely not a chemist, but after a few basic organic chemistry courses some of this research is making sense (I.e. the Fenton Reaction), but again I don’t have enough knowledge to know if this process is potentially harmful on the skin, and if I should continue use of topical Vit C or save my money from all of the marketing raves

I’ve heard Vitamin C’s ability to readily donate electrons, and thus acting as an anti-oxidant; however does this also mean that it readily reacts with other molecules after that process? Does the cycle continue such as Vit C then scavenging a donor/nearby cells or molecules (redox)? In the presence of catalytic metals (possibly in makeup other skincare products), could vitamin C react with those metals causing a pro-oxidant effect? I thought vitamin C reacts with oxygen, then producing superoxide that subsequently dismutes to produce harmful by-products such as hydrogen peroxide…the rest gets over my head but I am not sure now if the cons outweigh the benefits.
