The answer depends on the type of filler that was used. If it was a resorbable filler, such as hyaluronic acid, and it has already been completely reabsorbed, a fat transfer may be possible. However, if it was a non-resorbable gluteal filler, Dr. Alexander Aslani does not perform a BBL with fat, even if the patient believes the material has been removed.
The reason is not aesthetic, but medical: non-absorbable fillers can leave a silent risk in the tissue. Introducing fat into that area can activate that risk and become a difficult-to-manage complication.
Quick facts
- Resorbable filler: If it was hyaluronic acid and has been completely reabsorbed, a BBL can usually be considered.
- Non-absorbable filler: In Cirumed, it is a contraindication for BBL with fat transfer.
- Prior withdrawal: Even if you've been told the filler has been withdrawn, the risk doesn't necessarily disappear.
- Main reason: possible silent subclinical infection that may be activated by fat grafting.
- Objective: Protect the patient, do not force surgery with a disproportionate risk.
⚡ The essentials — what you need to know
One of the questions we always ask before considering a BBL is whether the patient has had previous injections in the buttocks. This isn't a minor question; it can determine whether the surgery is even possible.
In the case of non-absorbable fillers, Dr. Aslani considers them an absolute exclusion for a BBL with fat. The reason is that these products can remain dispersed in the tissue for years and can be associated with silent infections that don't cause symptoms until surgery triggers them.

Do you have a history of buttock fillers?
Before evaluating any BBL with fat, we need to know exactly what product was injected, when, and if documentation exists. A video consultation allows us to review your case honestly.
Why do we ask about fillers in every consultation?
A history of gluteal filler injections is one of the standard questions in Cirumed's assessment. The difficulty is that many patients don't know exactly which product they received. Sometimes they were told it was temporary, or they don't have any documentation of the product used.
That's why we ask in detail: what was injected, when, in what area, at which clinic, and if there is any report or label for the material. If it cannot be proven with certainty that the product was resorbable, Dr. Aslani treats it as if it were not.
This criterion may seem strict, but in high-volume surgery, the safety margin must be very high. Any doubt about the injected material cannot be resolved with optimism.
The difference that changes everything: resorbable or non-resorbable
Buttock fillers are divided into two very distinct groups. On one hand, there are resorbable products, primarily hyaluronic acid, which the body can metabolize over time. On the other hand, there are non-resorbable fillers, which remain in the tissue.
If the patient received a resorbable filler and the product has completely disappeared, the tissue may return to a state compatible with surgical evaluation. In that case, a BBL with fat may be possible, provided that the other safety criteria are also met.
The real problem arises with non-resorbable materials. They don't behave like an implant that can be removed in one piece. They disperse within the tissue, can migrate, and can leave a permanent risk.
This page is not a filler comparison.
This post is not intended to compare treatments or help you decide whether you should get fillers. Its purpose is to answer a specific question: If you've already had filler injected into your buttocks, can Cirumed perform a BBL using fat transfer?
For a general comparison between injectables and surgery, you can check out our guide on Liquid BBL vs. Buttock SurgeryFor specific information on resorbable products, please see the page of hyaluronic acid in the buttocks.
Here we focus only on the surgical contraindication when there is or could have been a non-resorbable filler.
Why non-absorbable filler makes a fat BBL impossible
Non-absorbable gluteal fillers can be associated with subclinical mycobacterial infections. These are silent infections: the patient may experience no pain, swelling, redness, or any symptoms for years.
The problem arises when a procedure is performed in that area. Fat transfer involves inserting a cannula, creating tissue trauma, and adding a significant volume of new biological material. This combination can trigger an infection that has been dormant for years.
Dr. Aslani explains it clearly: operating on that tissue can be like pouring fuel on a dying ember. The risk may not be apparent before surgery, but it can appear afterward in an acute and difficult-to-treat form.
How was this exclusion learned?
This criterion does not stem from an abstract theory. It comes from direct clinical experience. In previous years, before the field better recognized the danger of non-absorbable gluteal fillers, patients underwent surgery without knowing that the product they had been injected with was not absorbable.
In some of these cases, the fat transfer triggered a subclinical infection that was present but asymptomatic. The preoperative assessment showed no clear signs of the problem. This experience is why today this history is treated as an absolute exclusion, not as a flexible, case-by-case decision.
That's why we also insist so much on knowing about any previous injections in the buttocks, even if it happened many years ago or if the patient remembers few details.
Why is the answer still no even though the filler has been removed?
This is the hardest part to accept. Many patients think that if the filler is removed, the problem is solved. But non-resorbable fillers don't behave like implants.
An implant can be removed as a defined structure. A non-resorbable filler, on the other hand, disperses within the tissue. It cannot be removed cleanly and completely. Removing some of the material usually requires damaging surrounding tissue, and even then, some residual material almost always remains.
From a surgical safety standpoint, a patient who has had non-absorbable filler removed is not in the same situation as a patient who never received that product. The tissue's history does not restart.
Two additional problems with non-absorbable filler
Product migration
These products don't always stay where they were injected. Over time, they can migrate through anatomical planes and spread beyond the original area. Sometimes problems appear many years later, when the material is no longer confined to the initial buttocks.
Complications that are difficult to resolve
When a complication arises with an implant, the treatment usually follows a clearer approach: remove the implant, manage the problem, and, in some cases, consider subsequent reconstruction. With non-resorbable fillers, the material cannot simply be removed. If a complication occurs, it can become a persistent and difficult-to-manage problem.
Do you have a history of buttock fillers?
Before evaluating any BBL with fat, we need to know exactly what product was injected, when, and if documentation exists. A video consultation allows us to review your case honestly.
What can we value instead of a BBL?
The fact that a BBL with fat transfer isn't possible doesn't necessarily mean that nothing can be considered. It depends on each case, the type of filler, the affected area, the symptoms, the condition of the tissue, and the patient's goals.
In some cases, liposuction can be performed around unaffected areas, or body contouring can be done in other areas. What we do not do is inject fat into tissue that contains or may have contained non-absorbable filler.
The decision must be honest. It's preferable to clearly state what is unsafe rather than perform a surgery that Dr. Aslani considers disproportionate to the aesthetic benefit.
What documents should I bring?
If you have received gluteal injections, bring all available information to the consultation:
- Product name or brand.
- Approximate date of injection.
- Clinic or professional who applied it.
- Reports, labels, invoices or informed consent.
- Information on withdrawal attempts or subsequent treatments.
When it cannot be confirmed with certainty that the product was resorbable, the assessment is carried out with the utmost caution.
Other related security criteria
The history of filler use is not analyzed in isolation. It is part of a comprehensive safety assessment along with other medical and surgical factors.
You can find more information in our guide about BBL contraindications and in other specific criteria such as the BMI for BBL.
What does this mean for you as a patient?
If you've had buttock fillers, the most important question isn't whether the current result looks good, but what type of product remained in the tissue and what risks surgery might pose.
A patient may feel well, have no symptoms, and still not be a candidate for a BBL with fat if there is a history of non-absorbable filler. At Cirumed, safety takes precedence over the desire to operate.
The aim of the consultation is not to judge previous decisions, but to clarify what is safe to do now and what realistic alternatives exist.
FAQ
It depends on the type of filler. If it was a resorbable product, such as hyaluronic acid, and it has been completely reabsorbed, a BBL with fat transfer may be possible. If it was a non-resorbable filler, Dr. Aslani does not perform BBLs with fat transfer.
You must bring all available documentation: product name, clinic, date, invoice, or report. If it cannot be definitively confirmed that the product was resorbable, Cirumed treats it as if it were not, because the risk of error is significant.
The exclusion still applies. Non-absorbable filler can almost never be completely removed because it disperses within the tissue. Even if some of the material has been removed, residue may remain, posing the same silent risk.
Because a subclinical infection can exist without causing symptoms for years. Surgery, the cannula, local trauma, and fat grafting can activate that infection and turn it into a difficult-to-treat complication.
Not necessarily. If the hyaluronic acid was truly resorbable and has completely disappeared, surgery may be considered. To better understand this type of product, you can read our page on hyaluronic acid in the buttocks.
It depends on the case. Sometimes liposuction can be considered in unaffected areas, or body contouring in other areas. What is not done is transferring fat into tissue that contains or may have contained non-absorbable filler.
