Is this fluid or fat under my breast? (Photos)

Sorry for your bad experience.  Fluid 1.5 years post-op would be unusual.  It's impossible to tell without an in-person exam, but you are likely dealing with a bit of loose skin as a result of having the implants taken out.  I'm glad that you have a plan to have this taken care of and get a better result.  Best of luck to you!

I am sorry to hear about your past experience. Fortunately, most patients to do very well with visions. It is difficult to determine from a single photograph what maybe going on, but an in-person consultation will is to develop a treatment plan to achieve your goals. Good luck.
