My brown spots from sunbathing were either gone or lightened after healing from the 2nd IPL treatment and I was very satisfied with the results. But after 1 year,the brown spots have returned despite using the doctor recommended sunscreens and extremely limited sun exposure.
Additionally I noticed several months ago that my face had also lost some of its fullness and youthfulness, especially high up on my cheekbones. I can honestly say that there are no long term pros to IPL despite what the medical professionals claim.
The cons are plentiful: expensive, painful even with the numbing cream (used it both times), ugly during recovery (allow 1 week and make-up will NOT cover the ugliness up!) and discoloration returns long term.
