Of the choices above, if you were forced into one of them, which and why?
Yes, the treatment would rid you of all hair there, so to add more benefit (or lack of benefit) to this.
When you have a job that requires you to have a fresh shave daily, sometimes have to shave even twice a day. The laser hair removal for the beard would be extremely convenient and save so much time in the long run. Its just unfortunate that eventually down the line youll probably deeply regret it.
Keep in mind though of the pain going into it. Honestly as someone who has had treatments in many areas of my body, keep note that the mustache area is one of the most sensitive areas on your body. You feel it.
If i could choose my ass it would be my number 1 choice. Second would be my back.
Out of those i have to choose armpit. I like beard, crotch is tempting but i can shave them off if i ever want, nipple and chest are doesn't matter to me at all.
