I'm in the middle of IPL treatments for hair removal (legs, underarms, navel, toes, everywhere!!) and just finished with the IPL photofacial treatments for my acne. I love it!!! I REALLY do not think it hurts much - feels like a rubber band snap. Ouch and its over. :) It may take a few more treatments for total acne removal... I have very mild acne (so my friends tell me, I think its horrible), and it definitely helps lessen the severity and frequency of the breakouts. I also began using the recommended skin care line (Obagi) and that really gave the results a huge boost too.
I had been dying to do the hair removal since I can remember, and my staff got me a package at Rajeunir med spa for Christmas. The results are awesome and totally amazing! I love the staff there, they are all dolls.
It is by far the priciest thing I've done "beauty" wise - no plastics for me (yet...). If its worth it to you, then you should go for it.
