Breast augmentation with your own fat: what breast lipofilling is and when it is advisable

What does breast lipofilling involve?

Breast lipofilling is an operation that uses the body’s own fat to increase the volume of the breast. The technique is based on taking fat by liposuction, processing it under sterile conditions and then injecting it into the breast tissue.

The fat used is usually taken from areas such as the abdomen, the flanks, the outer thighs or the thighs, places where deposits of fatty tissue habitually build up.

The procedure is divided into three stages:

1. Selective liposuction: the fat is taken with fine cannulas from the areas where there is an excess.
2. Purification of the fat: the tissue taken is centrifuged, decanted or filtered to remove impurities, blood and fluids.
3. Injection into the breast: the purified fat is carefully injected into different layers of the breast tissue, respecting its blood supply and anatomical distribution.

The aim is for the fat to integrate and survive stably in its new surroundings. That integration depends on many factors, such as the injection technique, the blood supply of the receiving area and the patient’s general health.

In which cases is augmentation with your own fat indicated?

This technique is particularly indicated in women who want a discreet, natural result without using implants. It is ideal for:

• Patients who do not want breast implants.
• Women with small breasts looking for a slight or moderate improvement in shape and volume.
• Cases of mild breast asymmetry, where the aim is to even up the size of the two breasts.
• Secondary corrections after an augmentation with implants, to improve the contours or camouflage irregularities.
• Patients already having body liposculpture who want to use the fat removed for the breast.
• Breast reconstruction after mastectomy or lumpectomy, as part of an overall treatment.

In all these situations, lipofilling allows precise work on localised areas, adding volume with a natural texture and with no risk of rejection.

What are the benefits of breast lipofilling?

Using your own fat in a breast augmentation offers many advantages, both aesthetic and functional. Among them:

• A completely natural result to the touch and to the eye.
• No foreign body, which removes the risk of rejection or capsular contracture.
• A simultaneous improvement in body contour thanks to the liposuction.
• Minimal scars and a quick recovery.
• A safe technique with a low rate of complications.
• The possibility of reshaping specific areas of the breast with great precision.

What is more, being an autologous procedure (using material from your own body), it avoids the problems associated with implanting external materials, such as rupture, movement or the need for replacement.

Does this technique have limitations?

Although it is an advanced and effective technique, breast lipofilling has some important limitations that should be known before a decision is taken.

• The volume that can be added per session is limited. Generally, one cup size is achieved, or an improvement in shape and projection. If a significant increase is wanted, it may require several sessions.
• Part of the fat injected does not take (around 30%, although it varies according to a number of factors) and is reabsorbed by the body. The final volume is therefore assessed after a few weeks.
• Not every patient has enough fat to take, particularly women who are slim or very athletic.
• The technique demands surgical precision and experience to ensure the fatty tissue survives and to avoid complications such as fat necrosis or calcifications.
• It is not indicated for every type of breast or for every aesthetic goal.

For that reason an individual medical assessment is essential in determining whether a patient is a suitable candidate and what result can be expected.

What results does breast lipofilling give?

The final result is a breast that looks and feels completely natural. No edges or irregularities are felt, and the tissue has the same movement and elasticity as a breast that has not been operated on.

Most patients highlight as the main benefits:

• The harmony with the rest of the body.
• The softness to the touch.
• The absence of obvious scars.
• The improvement in self-esteem without the sensation of carrying something foreign.

It is important to have realistic expectations: this is not a technique for large increases but for those who put a natural look, discretion and an individual result first.

The published figures put numbers on all this. The standard systematic review, covering 3,565 patients, puts mean retention of the grafted volume at 62.4%, with a very wide range between studies (44.7% to 82.6%): in other words, around a third is reabsorbed, and exactly how much cannot be promised in advance. The overall complication rate was 17.2%, and the most frequent were areas of hardening (33.3% of them), persistent pain (25%) and bruising (16.4%). Patient satisfaction was 92%.

⚠️ And there is one consequence worth knowing before surgery: fat grafting leaves microcalcifications in 9% of cases and macrocalcifications in 7%. That does not prevent breast cancer screening or make it less reliable, but it does mean the radiologist has to know that lipofilling has been done, because these are findings that have to be interpreted correctly. It sits perfectly well alongside routine mammograms; what it cannot do is go unmentioned.

Is it compatible with other techniques?

Yes. Lipofilling can be used on its own or alongside other operations. For example:

• In breast augmentation with implants, fat can be injected around the implant to improve the aesthetic result and camouflage edges or add volume.
• In breast lift with augmentation, it helps fill specific areas the implants do not reach.
• In breast reconstruction after cancer, it can be used on its own or in combination with expanders, implants or flaps.

Combining techniques allows the treatment to be tailored and adapted to each patient’s real needs.

What aftercare does it need?

Recovery is more comfortable than with implants, although it calls for some specific precautions:

• Not undertaking strenuous physical exertion in the first few weeks.
• Wearing compression garments over the liposuctioned areas.
• Avoiding direct pressure on the breasts during the period of integration.
• Following a suitable diet to help the blood supply reach the fatty tissue.

Recovery is usually quick and progressive. Returning to work can happen within a few days, and sport from 3 or 4 weeks onwards, according to progress.

Breast augmentation with your own fat is an advanced, safe and effective technique for anyone wanting to improve the shape and volume of their breasts without resorting to implants. It gives a natural, individual result, using the body’s own resources to achieve an overall aesthetic improvement.

Its indication must nevertheless be carefully assessed by a plastic surgeon experienced in lipofilling. At the Instituto de Cirugía Plástica del Mediterráneo we carry out a complete assessment to establish whether this technique is right for you and what results you can expect. If you are looking for a natural alternative, minimally invasive and with no synthetic materials, breast augmentation with your own fat may be an excellent option.
