I used 0,3mm roller on a small patch of the face and another patch on the body, for comparison. There are no marks on the skin visible but in both places the skin feels a bit irritated. It feels like after having put your hand into a cactus pot that has those very fine needles that you're later trying to take our but you can't find any. Ah so that's how a tiny punctures in the skin feel like! Fascinating :) it's been one night and the sensation is this still the same.. I guess until it stops I should be careful with it..
[Update]
So after a few days I tried it on the face. Same sensation but it was gone after 1+ day. After that the skin was a bit redish, and after it it became kind of.. thicker.. at least when I touch it I feel it less.. not exactly what I was looking for.. I have the impression that all the impurities became even more pronounced since they are sticking out more.. will wait some weeks to see if there is any other improvement, but regarding wrinkles or skin pores - no difference so far.
