What should I expect

I’m a female - 40 - suffered ‘shadow’ on my bikini area and armpits ALL my life. At least my armpits don’t get bumps and ingrown hairs, but my bikini area does. Its hopeless. I’ve done waking at home with varying degrees of success, but I’m ready to just have a professional do it.

So, should I expect that I’ll be smooth when I’m done? And for how long? I generally have to shave my armpits 2x a day in the summer if I’m going sleeveless (5’oclock shawdow type thing) and my bikini area would be the same if I could stand it, but instead put up with that torture only once a day.

Basically, what should I expect?
