What you’re noticing is actually quite common. After a BBL, it’s normal for some of the transferred fat to be naturally reabsorbed by the body. Typically: Initial results: Right after surgery, swelling can make the buttocks look fuller than the final result. Fat retention: About 60–80% of the fat that survives the transfer usually remains long-term, but this varies from person to person. Weight changes: If you lose weight after your BBL, you may notice a decrease in volume, because fat in the buttocks (including transferred fat) can shrink along with overall body fat. If your goal is to regain the lost volume, there are a few options: -- Non-surgical approaches: Maintaining or slightly increasing your overall body weight may help, but results can be unpredictable. -- Surgical revision: Some patients choose a touch-up BBL to restore or enhance volume. A consultation with a board-certified plastic surgeon would help determine if this is appropriate and safe for you (Click on the supporting link of this answer!)
