I am half way through a course of laser on my bikini area and although the first time was incredibly painful (I put it up there with childbirth!) I am so thrilled with the results and very happy I have gone through the process. The second and third times were far less painful (less hair to zap, and I was more mentally prepared).
The results have been amazing and I haven't had a single ingrown hair since and my skin is baby smooth. I can't recommend it enough (for the bikini area) if you can put up with a painful first treatment. The treatments take about 15 mins, so it's over very quickly.
I showed the results to the beautician who used to do my Bikini waxes and she's booking in to go herself ha ha.
I went through the Harley Medical Group, Wimbledon branch.
Good luck
