Hello eijam_, I appreciate your questions! Brazilian Butt Lift (BBL) results can be permanent. Usually, a highly skilled and experienced plastic surgeon will achieve around 65% to 85% survival rate of the fat cells, and the rest will be harmlessly reabsorbed by the body. BBL patients can actively contribute on the success of the procedure and longevity of the results by following their surgeon’s recovery recommendations. Plastic surgeons have different post-operative protocols, customized for each patient’s needs and specific requirements. I typically suggest my patients avoiding cigarettes and heavy drinking because these habits reduce circulation throughout the body, leading to the degradation of new cells. Another fundamental measure is wearing specialized compression garments around the clock (except for showering) during six months, to reduce swelling and help their skin contract smoothly to their new body’s contours. Additionally, at least ten lymphatic drainage massage sessions are required, starting 24 hours after the procedure, to eliminate excess lymph fluid, alleviate swelling and discomfort, and also prevent complications such as seromas (fluid collection) and contour irregularities (indentations, and/or fibrosis). In my experience, patients who successfully avoid sitting or putting pressure on their buttocks or stretching for the first 8 weeks after their surgery are much more likely to have long-lasting results than patients who fail to follow this advice. Hope this is helpful! Dr. De La Cruz.
