What is a BBL?
A Brazilian Butt Lift (BBL) uses autologous fat transfer to enhance buttock volume and shape. Fat is harvested via liposuction from donor areas (typically abdomen, flanks, back, thighs), purified, and injected in multiple layers for a natural, proportional result.
BBL has become one of the fastest-growing aesthetic procedures internationally. Modern technique focuses on more than just volume increase — it emphasizes proportional shaping (waist-hip ratio, balanced volume distribution between upper, middle and lower buttock zones). Same-session liposuction of the abdomen and flanks emphasizes the buttock contour by narrowing the waist.
Who is a candidate?
Candidates include patients with buttock volume deficiency, flatness or asymmetry, body-disproportionate buttock appearance, postpartum or weight-loss buttock volume loss, and those with sufficient donor fat available via liposuction.
Ideal candidate: stable weight, BMI 22-30, with sufficient donor fat (abdomen, flanks, back, thighs), and realistic expectations. Very thin patients with insufficient donor fat are limited candidates — this is BBL's most common limitation.
How is the surgery performed?
Under general anesthesia. Liposuction first removes fat from donor areas (abdomen, flanks, thighs). Harvested fat is processed and purified, then injected into the buttock with very fine cannulas in multiple layers. Surgery takes 2-4 hours.
Safety is critical: BBL has historically had the highest mortality risk among plastic surgeries due to fat embolism (fat particles entering blood vessels). The modern safe technique restricts fat injection to subcutaneous (above-muscle) layers only; intramuscular injection is strictly avoided. This principle has dramatically improved safety. Clinics performing intramuscular injection are not recommended. Dr. Erdal's practice follows the safe subcutaneous-only technique.
How much fat survives?
Typically 50-70% of transferred fat becomes permanent. Some absorption is normal in the first 3 months. Final result is visible at month 3.
Preoperative preparation
Smoking should be stopped at least 4 weeks before surgery. Stable weight is required. Standard preoperative tests are performed.
Recovery timeline
First 2 weeks: No sitting on the buttocks (to avoid pressure on fat grafts). Side or face-down positioning. A special BBL pillow may be used. Compression garment on liposuction donor areas.
Weeks 2-4: Gradual short-duration sitting can begin. Most patients return to work in this period.
Months 1-3: Fat graft survival (typically 50-70%) consolidates. Final result visible at month 3.
Month 6: Final result.
Risks and complications
Fat embolism (most serious risk): Modern subcutaneous-only injection technique minimizes this risk substantially.
Other risks: liposuction-related complications (contour irregularities, hematoma), infection, asymmetry, greater-than-expected fat resorption (revision rate 10-20%).
BBL in Istanbul — Assoc. Prof. Dr. Ayhan Işık Erdal's practice
Dr. Erdal's private clinic is located in central Istanbul, in the Nisantasi district. Address: Teşvikiye Cad. No:9/12, Istanbul. The clinic is easily accessible from major Istanbul hotels and from Istanbul Airport (IST) and Sabiha Gökçen Airport (SAW).
BBL is one of the most popular aesthetic procedures in Istanbul's medical tourism market — but also among the most safety-sensitive. International patients should specifically confirm that their surgeon adheres to the subcutaneous-only safe injection technique. Dr. Erdal's Istanbul practice follows this principle strictly. Hospital partners are accredited facilities in central Istanbul with full anesthesia and intensive care infrastructure.
International patient coordination includes: video consultation prior to travel, airport-hotel transfer, English-speaking medical team, accommodation at partner hotels, and full postoperative follow-up. Patients typically stay in Istanbul for 10-14 days following BBL — sufficient for initial postoperative review and clearance for safe travel home (with sitting precautions still maintained during travel).

Frequently Asked Questions
Avoid direct sitting on the buttocks for 2-3 weeks. Special cushions are recommended. A compression garment is worn for 6 weeks.
When performed by an experienced surgeon with proper technique and in accredited facilities, BBL is a safe procedure. Safety protocols are critically important.
Most commonly the abdomen, flanks, back, and thighs. Multiple donor sites are used to achieve adequate fat volume and simultaneous body slimming.
Avoid direct sitting for 2-3 weeks. Use a BBL pillow when sitting is necessary. Normal sitting gradually resumes from week 3, with full freedom at 6 weeks.
BBL uses your own fat for natural feel and appearance, plus provides liposuction benefits. Implants are silicone prostheses. BBL is more commonly preferred for its dual benefit.
Minimum fat reserves are required. Very thin patients may not have adequate donor fat. Buttock implants may be an alternative. Eligibility is assessed during consultation.
Light walking from week 1. Lower body exercises at 6-8 weeks, intense sports at 8-10 weeks.
With an experienced surgeon, BBL produces natural, proportional results. The goal is harmonious enhancement, not exaggeration.
Once fat cells stabilize (approximately 3-6 months), the surviving fat is permanent. Weight maintenance is important for long-term results.
Modern subcutaneous-only fat injection techniques have dramatically improved BBL safety. When performed by experienced surgeons in accredited facilities with proper protocols, BBL is a safe procedure.
