I asked my laserist about it as they do treatments using a stronger dermaroller at my spa. She said everyone loves the at home one, and it's better than anything in the past (micodermabration)It can be almost therapeutic but you have to remember to set aside the time (few minutes) to do it. Which reminds me.....
So far,so good. Just got to get use to rolling it across my face in certain areas. Guess over time, I'll have developed thick skin physically and emotionally to tolerate better. Other than that, I am pleased with my purchase.
