I use it with great results. I don't even use it every day and it works, and I have thick dark chin hair. I put a very thin coat on, and a tube lasts more than two months.
At $35/tube, I save $$ using it instead of waxing.
I highly recommend you try it and see how you respond, I haven't heard from anyone else who's had it not work and really, just knowing that there's something available that works even if you don't decide to keep using it could be a comfort.
I had my OBGYN call in my prescription without making an appointment, so I don't think there's any reason your family doctor or whomever couldn't do the same thing so you can avoid the expense of a doctors visit for the scrip.
