The Brazilian Butt Lift (BBL) has evolved more in safety than any other cosmetic procedure of the last five years. In Medellín we strictly follow the MIS-BBL protocol (Multi-society BBL safety guidelines) that virtually eliminates fat embolism risk.

Quick essentials

  • BBL is fat transfer: your own fat is injected into the buttocks. No implants, no foreign bodies.
  • Survival rate: 60–75% of transferred adipocytes. The rest is reabsorbed in the first 3 months.
  • MIS-BBL protocol: injection only in the subcutaneous plane, never intramuscular.
  • Pricing in Medellín: USD 3,200 – 5,000.

What is a BBL exactly?

Brazilian Butt Lift = liposuction + fat transfer to the buttocks, done in one surgical act:

  1. Liposuction of donor areas (back, flanks, abdomen, arms).
  2. Fat is gently processed by decantation or centrifugation.
  3. Injection into the buttocks layer-by-layer using rigid cannulas, only in the subcutaneous plane.

The “Brazilian” name comes from pioneering work by Brazilian surgeons in the 1990s, but today’s procedure is dramatically safer.

The MIS-BBL safety protocol

Until 2018, BBL had the highest mortality among cosmetic surgeries (1 in 3,000 cases per ASPS data). Cause: intramuscular injection caused fat embolism through deep gluteal veins. The MIS-BBL protocol sets three absolute rules:

  1. Zero intramuscular injection. Subcutaneous plane only. This is the most important rule.
  2. Cannulas of at least 4 mm, rigid (not flexible).
  3. Constant cannula motion during injection — never static.

If your surgeon doesn’t mention MIS protocol or doesn’t use ultrasound guidance, look for another option.

Am I a candidate?

  • Adequate donor fat: minimum 1.5–2 liters available across all areas.
  • BMI between 22 and 30. Very thin patients lack donor fat; very heavy patients may need a two-stage approach.
  • Good gluteal skin quality without extensive stretch marks.
  • No history of thrombosis or coagulation disorders.
  • Willingness to respect prone position for the first month (sleeping face-down).

2026 BBL pricing in Medellín

Range: USD 3,200 – 5,000. Factors that drive cost:

  • Number of liposuctioned areas (more areas, more OR time).
  • Volume of transferred fat.
  • Add-on procedures (simultaneous mastopexy or abdominoplasty).
  • Type of OR and anesthesia (always third-level facility with ICU).

Realistic recovery timeline

  • Days 1–14: no direct sitting on buttocks. Sleep prone or sideways. U-shaped cushion if sitting is unavoidable.
  • Day 7: first follow-up, gentle manual lymphatic drainage.
  • Week 2: office work resumed with special cushion.
  • Month 1: normal sitting allowed. Continue manual drainage.
  • Month 3: preliminary result visible. Reabsorbed fat is gone.
  • Month 6: final result. Surviving fat stays permanently if weight remains stable.

Real risks to know

  • Asymmetry: body reabsorbs fat unevenly. 5–10% of patients want a touch-up at 12 months.
  • Seromas: 3–5%, drained in office.
  • Fat necrosis: firm nodules that may need removal.
  • Fat embolism: < 0.01% with strict MIS-BBL protocol.

For international patients

Recommended stay in Medellín: 14 days minimum. We coordinate José María Córdova airport pickup, partner-hotel rates in El Poblado, English-language consultation and remote follow-up by video. Most international patients fly home at day 12–14 after the first major check-up.
