29 / red head / fair skin / had first implants 1-13-15 mentor HP saline 250 filled to 275. Apx 3 years after I noticed my scar was up on my implant and not in the crease but they still looked good I thought. 7-11-19 I had a kidney Transplant and gained apx 40-50 lbs and can really see they have bottomed/double bubbled. It’s been almost 9 years so I would like them redone and bigger but I’m nervous to have them bottom out again. What would be the best way to prevent this in my case?
