I had 5 laser sessions a while ago and it just didn't work out for me so I had to move to electro.
I found a pretty chill lady who does it and she's cool and people have said nothing but good things about her work so I'm going to use her. The one big difference that I have seen though is that electro does hurt more lol. For having it on a lower setting it was still giving me some fun hurting haha.
She's working on my chin first because that's where pretty much all of my hair is so I have no doubt that it's still probably going to take a lifetime to finish. Anyways just wanted to chime in my two cents here to give my experiences.
