Autologous Fat Gluteoplasty: Complete Guide to Buttock Augmentation Without Implants

Autologous fat gluteoplasty—also known in English-speaking contexts as a Brazilian Butt Lift—is a body-contouring surgical technique that increases and reshapes the buttocks using fat harvested from the patient’s own body. Unlike implant-based augmentation, this procedure uses biologically compatible tissue, transferred from donor areas such as the abdomen, flanks, or thighs, after a purification process using centrifugation.

At Mallorca Medical Group, Dr. García Ceballos FCCP, a plastic surgeon with more than 34 years of clinical practice and specialized training at the Université Libre de Bruxelles, assesses each case individually to determine whether this procedure is the most appropriate and safe solution for each patient. This guide provides a complete medical overview of the procedure, its indications, surgical technique, recovery and expected results.

What is fat gluteoplasty and what does the procedure involve?

Autologous fat gluteoplasty combines two interventions in a single surgical procedure: liposuction of the donor areas and fat grafting to the buttocks. The process includes the following stages:

• Fat harvesting: using precise liposuction in areas with sufficient fat deposits—typically the abdomen, flanks, lower back, or thighs.
• Processing of adipose tissue: the harvested fat is centrifuged to separate viable components from cellular debris and tumescent fluid, obtaining a purified concentrate ready for reinjection.
• Fat grafting: the purified fat is injected into multiple planes of the gluteal subcutaneous tissue using small-calibre cannulas, distributing the volume anatomically to achieve a natural, proportionate result.

The procedure is performed under general anaesthesia in a certified operating theatre, with an approximate duration of 2 to 3 hours depending on the volume to be treated and the donor areas involved.

Suitable candidates: indications and contraindications

Not everyone is an appropriate candidate for this procedure. The personalised preoperative assessment at Mallorca Medical Group determines each patient’s suitability based on objective clinical criteria.

Profile of a suitable candidate:

• People who wish to improve buttock volume and projection in a natural way.
• Patients with sufficient body fat in available donor areas.
• Individuals at a stable weight for at least 3–6 months prior to surgery.
• Good general health, with no anaesthetic contraindications or conditions that increase surgical risk.
• Realistic expectations regarding the outcome, acknowledging the possibility of variability in fat resorption.

Main contraindications:

• A low body-fat percentage that prevents having sufficient donor areas.
• Frequent weight fluctuations or a body mass index outside the appropriate range.
• Conditions that compromise healing or immune response.
• Uncontrolled coagulation disorders.

Surgical technique: liposuction and fat transfer

The quality of the outcome depends, to a large extent, on the technique used at each stage of the procedure. Dr. García Ceballos FCCP uses small-diameter cannulas for fat harvesting, minimising cellular trauma and preserving the viability of the transplanted adipocytes.

The processing of adipose tissue follows validated centrifugation protocols to obtain a fat concentrate rich in viable cells and cell growth factors. The infiltration is performed in multiple passes and subcutaneous planes, avoiding large volume deposits in a single point -a practice that increases the risk of fat necrosis-.

“The key to a lasting result in gluteoplasty with autologous fat lies not only in the volume transferred, but in the quality of the graft, the anatomical distribution and the rigorous postoperative follow-up. Each case requires individualized planning that takes into account the characteristics of the tissue, the patient’s anatomy and his or her real expectations.”

Surgical safety: risks and how they are minimised

Autologous fat gluteoplasty has a safety profile that, in the hands of a specialised plastic surgeon and with appropriate protocols, is favourable. However, like any surgical procedure, it involves risks that should be understood and discussed during the preoperative medical consultation.

Risks inherent to the procedure include:

• Variable fat resorption: between 20% and 40% of the transferred volume may be resorbed during the first months. Planning the volume to be transferred should take this variability into account.
• Postoperative asymmetry: possible differences in volume between the two buttocks that, in relevant cases, may require a corrective session.
• Fat embolism: a serious complication but with a low incidence when the graft is placed exclusively in the subcutaneous plane, avoiding muscle tissue. This is the main reason current protocols restrict deep intramuscular injection.
• Infection and seroma: general risks of any surgical procedure, minimized by antibiotic prophylaxis and adequate management of tumescent fluid.

At Mallorca Medical Group, patient safety guides every surgical decision, from candidate selection to postoperative follow-up.

Recovery and postoperative care

The postoperative period after autologous fat gluteoplasty has specific features that distinguish this procedure from other body-contouring surgeries.

The most relevant indication is to avoid direct pressure on the buttocks during the first 3-4 weeks. This implies using a special cushion for sitting during this period, sleeping in prone or lateral decubitus, and limiting sitting times. This measure preserves the irrigation of the fat graft and favors its integration.

The use of compression garments in the donor areas (abdomen, flanks) is mandatory for 4-6 weeks. Swelling and bruising in the treated areas are to be expected and resolve progressively.

The return to sedentary work activity may occur between weeks 2 and 4. The practice of sports should be postponed until 6-8 weeks, with a gradual and supervised start. The definitive result is appreciated between 3 and 6 months after the intervention.

Expected results: natural appearance, projection, and durability

Autologous fat gluteoplasty can achieve an aesthetic improvement in the gluteal contour that, once the graft stabilises, offers natural and long-lasting results. The fat that survives the initial resorption period—typically the first 3–4 months—tends to behave like native tissue, responding proportionally to the patient’s weight changes.

The results are variable according to the individual anatomy, the quality of the available fat, the follow-up of postoperative care and the maintenance of a stable weight. In no case can a specific result be absolutely guaranteed; the aesthetic improvement is evaluated in relation to the initial morphology of each patient and the expectations agreed upon in the previous medical consultation.

Compared to buttock implants, autologous fat provides a more natural texture to the touch and eliminates the risks associated with foreign bodies – capsular contracture, rupture, displacement. However, it is not suitable for all cases, especially when considerable volume increases are required in patients with limited fat reserves.

Frequently asked questions about fat gluteoplasty

How much fat is absorbed after gluteoplasty with your own fat?

The resorption rate of transplanted fat varies depending on the patient, their metabolism, the technique used, and postoperative follow-up. In general terms, between 20% and 40% of the transferred volume may be resorbed during the first months. For this reason, planning the volume to be transferred must take this variability into account. An individualised medical assessment makes it possible to estimate the expected outcome more accurately.

Who is a suitable candidate for autologous fat gluteoplasty?

A suitable candidate is someone who wishes to improve the contour and volume of the buttocks without implants, has sufficient fat in donor areas (abdomen, flanks, thighs), is at a stable and healthy weight, and maintains realistic expectations about the outcome. It is not suitable for patients with a very low body-fat percentage, nor for those who cannot undergo general anaesthesia. The preoperative assessment determines suitability in each case.

Is gluteoplasty with your own fat safe compared with implants?

Autologous fat gluteoplasty offers advantages in terms of biocompatibility, as it uses the patient’s own tissue, eliminating the risk of rejection or capsular contracture associated with implants. However, like any surgical procedure, it carries its own risks—such as fat embolism, infection, or asymmetry—which are minimised through rigorous surgical protocols and appropriate candidate selection. No surgical procedure is risk-free; therefore, patient safety is the central focus of planning at Mallorca Medical Group.

How long does recovery take after gluteoplasty?

Initial recovery covers the first 2–3 weeks, during which the patient should avoid sitting directly on the buttocks to preserve the fat graft. Special cushions are used to facilitate rest and getting around. Discomfort gradually decreases. Returning to sedentary work usually occurs between weeks 2 and 4. Intense physical activity should not be resumed before 6–8 weeks. The final result is seen from 3–6 months, once the transferred fat has stabilised.

Gluteoplasty with autologous fat is a body surgery option with a natural results profile and specific advantages over the use of implants, in those cases in which the patient’s anatomy and fat reserves allow it to be performed. Detailed preoperative assessment, precision surgical technique and rigorous postoperative follow-up are the determining factors in obtaining the best possible result for each individual case.

As in all cosmetic surgery, the results are variable and depend on individual factors that are assessed in the medical consultation. The decision to intervene should be made in an informed manner, with realistic expectations and advice from a licensed and registered plastic surgeon.
