Yeah buddy, they are both "concealers", in that they conceal or hide... whatever it is you're trying to hide. The difference between them is pretty great though. Dermatch is kind of a powder that you apply almost like you were applying make up (it even comes in a make up case). It takes some getting used, the application process is just that... a process. As for Toppik, the idea of it is much simpler, but I'm not sure it's as effective as Dermatch is by someone who mastered it. It's definitely easier though, I don't think anyone will deny that. For the scar area though, I'd go with Dermatch.
