Fat transfer (BBL): how does natural volume gain with your own tissue work?

Fat transfer (sometimes called "augmentation with your own fat", and known in the context of the Brazilian style of buttock augmentation as BBL — Brazilian Butt Lift) is a method that uses the body's own tissue instead of an implant. The idea is simple: fat is taken by liposuction from an area that has a surplus of it (usually the abdomen, the waist, the thighs), purified, and injected again into the desired area (buttocks, breast, face). Behind that "simple" principle, however, lie a careful technique and the management of realistic expectations.

How does the procedure work?

It consists of three main stages:

1. 1Harvesting fat from the donor area — with a liposuction technique (usually a fine cannula) fat cells are removed from areas such as the abdomen, the waist or the thighs. This stage also improves the contour of the donor area at the same time.
2. 2Purification — the harvested fat is separated from blood, fluid and damaged cells by centrifuge or by filtration. Only healthy, living fat cells are selected.
3. 3Reinjection — the purified fat is transferred to the target area with small needles, in many thin layers. This makes it easier for the fat to connect with the blood supply and "take", that is, to survive.

Body areas: where is it applied?

• Buttocks and thighs (BBL) — the most requested field of application, to give the buttocks natural fullness and proportion
• Breast — in patients who do not want an implant and are looking for a small to moderate gain in volume
• Back of the hand — restoring volume where thin skin with visible veins reads as a sign of age
• Face — to restore lost volume in areas such as the cheeks, temples and under the chin (in purpose this is close to botox and filler procedures, but the effect is lasting)

The reality of partial resorption — an important expectation

Not all of the transferred fat stays for good. The body naturally resorbs some of the cells that fail to connect with a new blood supply. Because of this:

• The surgeon usually injects more fat than the desired result requires — in order to account for resorption in advance
• The final result stabilises 3-6 months after surgery — the volume of the first weeks is temporary
• In some cases a second, small "top-up" session may be needed — this is a point to be discussed in advance at the consultation
• The degree of resorption differs from person to person — the same technique does not give the same result on every body

Who is it suitable for?

• Those with a sufficient reserve of donor fat (in very slim bodies the method is limited because donor fat is scarce)
• Those who want to avoid the "artificial" feel of an implant and want volume from their own tissue
• Those looking for an improvement in shape and proportion rather than a dramatic change of size
• Those whose general state of health suits liposuction combined with an injection procedure

Safety notes

Fat transfer, particularly in the buttock area, can carry serious risks if it is not performed correctly — injecting fat into the wrong layer (inside the muscle) can in rare cases be dangerous. Therefore:

• It must be performed only by a certified plastic surgeon experienced in this specific technique, in appropriate clinical conditions
• The injection must be made only into the subcutaneous fat layer, with a superficial technique
• Do not hesitate to ask your surgeon beforehand about their specific technique and experience

Baku market range (2026)

The price of fat transfer varies widely according to the target area, the volume of fat required and the number of donor areas. An exact price is determined only at the consultation, after an assessment of the body.

Conclusion

Fat transfer offers a natural-looking gain in volume using the body's own tissue, but accepting the reality of partial resorption and choosing the right, experienced hands are conditions of it.
