Anyone done this and actually seen a difference? Have just got one and did first roll last night.
Am using 0.5 roller, not pressing hard (but still feeling it and winding up pink/red), The Ordinary Argireline solution on forehead/crows feet/smile lines afterwards. Planning on doing this 2-3 times a week, maybe one week on/one week off depending upon how skin feels.
I've tried to research this online but frankly every bit of info I read contradicts another... some say once a week, the info that came with the roller 5 days a week is ok... given that I'm sticking needles in my own skin I'd quite like to feel I'm doing it right 
Also anyone ever used one on cellulite??
