Thanks for your questions. In a Brazilian butt lift, fat is transferred from various parts of the body to the buttocks to re-shape and augment the buttocks. After the procedure, it is crucial to minimize or avoid sitting for prolonged periods. The reason is that the fat has not integrated to your tissues so the buttocks may flatten or loose projection. Further, sitting causes trauma to the newly placed fat so the process of blood vessel ingrowth, which is necessary for fat survival, may be disrupted. So I recommend that my patients minimize sitting for one month. If you have a sitting job, I recommend using a BBL pillow to minimize the trauma from sitting. After one month, I allow my patients to sit regularly although many continue to avoid it for several weeks. Regarding massages, you should have them as soon as possible. The massages help in draining excess liquid as well as avoiding post-liposuction imperfections. You should do about 2 massages per week for about 4-5 weeks. As for compression garments, they really help the outcome of the surgery. The intention of the garment is to compress areas of lipo and hold up the buttock area where fat is injected. I think it's very important that the garment is used everyday and only removed for showering purposes for up to 8 weeks. Some surgeons don't believe in them, but my patients have been very satisfied with how the garments helps the outcome. Hope this helps. Make sure the surgeon you choose has extensive experience in with BBLs and clean credentials. Always consult with a board certified plastic surgeon.
