i did laser down there and had no scarring or anything... pretty good results..
i was very happy with it and definitely consider it be one of the best things i ever did...
i started the process about... 6 years ago i think
and it took about 6 months with the treatments spaced out and everything was gone...
which was awesome..
i've had some regrowth since then (in the last couple years i think) and have lately been considering going in for a touch up but even the regrowth is pretty manageable...
whatever has come in has been sparser/thinner/less dense than before and can be taken care of with a quick swipe of the razor, no ingrowns really and no razorburn (which had been a big concern for me before the laser)..
i would recommend it... and they also have numbing creams to deal with the pain during treatments...
i never used any, but i have a high threshold for pain and my lady iced down the area to numb it up before starting...
probably a bit old school but it worked
