I recently got one of the one touch electrolysis units and tried it out a couple of weeks ago. I did a test on a few hairs and have been waiting to see how my skin ends up. On the box, it states that if you are sensitive to skin hyperpigmentation (injuries cause darkened scars) that you shouldn't use it. Unfortunately, I AM susceptible to to hyperpigmentation (at least I have been since I started HRT

). So far the test spots I did *have* left marks on my legs where I did it (like in 6 spots), so I doubt I'll be using that method. I already had plenty of those scars on my legs though, so it's not that big of a deal. I've at least figured out how to get them to fade. Hopefully I'll figure out something that gets rid of them.
by the way, I've also had experience with professional laser and electrolysis too and those haven't left marks, but actually now that I think about it, I only seem to have the hyperpigmentation problem on the lower half of my body. Maybe I should try the unit on a part of my upper body, although my armpits are about the only place I really have hair left that I'd want to remove.
