Your surgeon removes your fat tissue from unwanted areas and places it where volume or projection is needed. The procedure is not that simple; Fat tissue should be aspirated through liposuction in a minimally invasive way to maximize viability of the fat cells. These cells should be washed and then gently transplanted. There are many technical details that should be taken into consideration, this sheds light on the importance of choosing the right plastic surgeon to perform your procedure.

Fat viability

Fat viability depends on many factors: Fat tissue itself, technique used to perform the fat transfer, patient´s quality of life (avoiding smoking, exercising, diet among other factors). We have seen a significant difference in fat survival between patients who eat healthy diet, exercise and do not smoke as compared to those who don’t.


Fat should never be placed below or inside the gluteal muscles as this predisposes the patient to fat embolism, a condition where fat cells or tissue can travel the venous system and clog the lungs. Placing fat above the muscle is key for safe procedure and requires surgeon experience.

Aesthetic outcome

There are different philosophies and aesthetic standards that are used for BBL. At IMAGN Institute, we consider the buttocks aesthetics as a continuation of the lower back and thighs. Hence, in order to get a harmonious and aesthetically pleasant result, the structures surrounding the buttocks should often be addressed. The ultimate goal is to create smooth continuous curves with elegant fullness and projection.
