Kelly,
recently had it done on my top lip so was a bit scary having it done on the face. There are different types of laser machines but I don't know the differences. I certainly had no scaring or scabs or anything. You feel a bit of a zing but only similar to what you get with electrolysis. I had a bit of regrowth but not much. Apparently hair regrowth is often hormonal so pregnancy and menopause can trigger it so they don't guarantee no regrowth as they really can't tell what your body will do. I would go for it definitely.
I would have everything done if I could afford it. I am so glad it is around, as i have very dark hair and with DH being arabic, I can see DD already has dark hair so she won't have to worry about it.
