Ouch! would be your fist word if you're a first timer.:) At first you can really feel a little pain but when you get used to it, painful no more! Three hours ago, I went for an underarm waxing (not as a 1st timer) and guess what?..I really feel good after the session because I do have a smoother underarm now.
Anyway, I'll wait for another weeks before I'll do my next session and am so excited to try also their Brazilian waxing. :) By the way, you can also do underarm waxing at home if you wish to.
