My last session with my electroylsist, we were talking about her new machine(I guess the newest one on the market). She was saying, at first when you start, you do do damage when you do the first clearing. But later on when you have fewer hairs, it can be good for your skin. This new machine is a lot hotter, just as much heat as a laser. It seems that when you have treatment the heat helps activate collagen, which is good for your skin.
Actually, that was my last appointment. I am done with electroylsis. It took 2 years, and 10 months.
