IPL Ruined my Face

I had an IPL treatment 2 years ago and still seeing the damage coming out on my face! I had started out with some minor fine lines, some sun spots and large pores. Was told that IPL would "clean everything" up and my skin texture would improve. After the procedure, my face swelled and my eyes swelled so much I could barely see. That went down after several days and for about 3 weeks, my face looked really good. Then the horror began. I noticed major hyperpigmentation on my cheeks and a big dent on my right cheekbone. Also my lower left cheek had started to droop. I was given prednisone for this "swelling" which did nothing. After that I began to develop crescent-shaped welts over my cheeks. These have gradually contracted down so I now have crescent-shaped depression scars on my cheeks and chin. I thought all the damage would have surfaced by now, but continue to notice increasing scarring. I am now on Tazorac to try to increase collagen production. We'll see ( I have a new doctor). I will probably end up having some sort of dermal filler to try to even out the scarring and holes that have come out on my face. I am devastated and rarely go out of the house except to go to work.
