Brazilian Butt Lift (BBL) with fat grafting is not just about injecting volume; it is about liposculpture, fat survival, and long-term volume balance. Patients tend to think only about the volume of fat that is transferred, not realizing that the secret to successful fat grafting is not just about volume, but fat quality, technique, and recovery.

The internet is flooded with “before and after” pictures, but the science of Brazilian Butt Lift is not just about pictures; it is based on science, precision, and the technique used during the procedure. As the trend in Europe is moving towards the “Athletic Look” or “Skinny BBL,” the focus is no longer just on volume, but on fat survival rates (PMC).
The Science of “Fat Survival”: Why Every Milliliter Counts
One of the biggest misconceptions is that if 1000ml is transferred, that is exactly what is transferred. In reality, what is transferred during Brazilian Butt Lift is not just fat; it is a combination of different substances.
According to Dr. Zykov, a leading expert in European liposculpture, the “lipocollector” contains live adipocytes, damaged cells, blood, and Klein’s solution (a specialized anesthetic liquid). While some clinics might boast about high injection volumes, the quality of that material is what actually dictates the result.
“If a doctor states that 1000 ml was injected, this could mean anywhere from 300 ml to 700 ml of actual fat tissue,” explains Dr. Zykov. “In my practice, I strive to achieve a ratio of approximately 70-80% fat tissue and 20-30% solution for optimal results.”
Interestingly, Dr. Zykov notes that leaving a small portion of the solution is actually beneficial, as it contains a high concentration of stem cells and growth factors that act as a “fertilizer” for the newly transplanted fat.
The Three Pillars of Permanent Results
To get results that will last you for years instead of months, the following three factors need to come together:
1. The Harvesting Technique
The technique used for fat harvesting will determine if it will stay or go. Dr. Zykov uses the tumescent liposuction technique because it’s the safest. It preserves the cell walls of the fat cells, allowing them to stay “alive” until they are transferred into the new site
2. The “Thin Layer” Principle
Fat cells don’t come with an immediate blood supply. They are sustained by the process of Neovascularization, whereby blood vessels develop into the fat cell.
- The Secret: The thinner the fat layer, the greater the survival rate. Too much fat injected into one area means the fat cells in the middle will “suffocate,” leading to necrosis.
3. The Recovery Protocol: “Protecting the Graft”
The fat cells need the first few weeks of recovery as a “blackout period.” Dr. Zykov explains how any physical impact can cause the fat cells to die before they can connect with the blood supply. That’s why BBL pillows are non-negotiable.

The “Weight Loss Hack”: Timing is Everything
Dr. Zykov’s clinic has come up with some of the most brilliant ideas for weight loss. One of the most interesting concepts is the timing of weight loss. Many women are concerned about losing weight after the BBL. However, there is a biological window of opportunity.
- The First Month: The fat injected into the body isn’t part of the body’s energy balance. Losing weight immediately after the operation will mean the body will take up the fat in the waist area for its energy. However, it will be unable to take up the fat in the buttocks.
- The Result: You will lose weight in the waist area while the BBL will still be plump.
- After 6 Months: After the fat is fully integrated into the body with its own blood vessels, it will be like any fat. Losing weight will mean the BBL will be slimmer.
Liposculpture is an investment in your self-confidence. By understanding the science behind fat grafting and choosing a specialist who prioritizes fat cell survival, you are ensuring that your curves are not just temporary. They are the permanent masterpiece of body sculpting.
