I am slim so there was no extra fat to do a fat transfer. The implant looks great but is extremely uncomfortable when sitting or laying on your back. It has been 3 years. I thought with time it would get better. I wish I could have talked to people who had done this before. I'm from the USA but I went to Peru because it was cheaper. So there is no going back to the Dr. If it were possible I would remove the implant and have fat put in. I don't know if this is a common problem.
