I got an IPL 10 days ago to remove a few brown spots on my face, using a Groupon. I ended up with painful burns and blisters. They've since healed, but I'm left with stripes on my face that are impossible to hide with makeup.
The doctor who owns the plastic surgery where I had the procedure done swears that the proper protocols were followed and the results would have been the same even if he had done it himself. I think they have a standard setting they use, and didn't take into account my Asian ethnicity.
I would urge anyone who wants to try IPL to make sure that they do a test patch before anything else. I would never recommend this to anyone. Groupon gave me a full refund.
