I’ve found that the burning smell is mostly in the air in the room that they are doing the lasering in, and less on me. I’ve not noticed any change in smell at all.
Also, my underarms have looked pretty much back to normal by the next day. I did once get a bruise from the laser that took about a week to resolve but fortunately it was pretty high up and I had to raise my arm up for it to be visible.
(Not sure what caused the bruise as the physician didn’t hit me with the laser – I am guessing that it was from a rather spectacular “hair pop” as the laser exploded it.)
I’ve had two treatments so far and the change in my underarms is pretty dramatic. I’m not totally hairfree yet – I’d estimate that about half of it is gone – but the hair that is left is MUCH finer. I could quit now and be happy with shaving, but I’m scheduled for my third treatment next Saturday.
