What is a BBL, and does the term always refer to surgery? It is an important question because BBL now describes both surgical fat transfer and non-surgical filler treatments.
A BBL, or Brazilian butt lift, is a buttock-augmentation procedure used to add volume and reshape the buttocks. A surgical BBL transfers a patient’s own fat after liposuction, while a non-surgical or liquid BBL uses injectable filler. These treatments involve different procedures, recovery periods, results and risks.
The distinction matters because surgical fat transfer and filler-based BBLs differ in the material used, anaesthesia, incisions, possible result size, recovery, longevity, reversibility, risks and cost. They should not be treated as interchangeable procedures.
At Deep Aesthetics, non-surgical BBL treatment is offered using filler rather than surgical fat transfer. The website lists London Canary Wharf and Birmingham clinics and currently displays a package price of £2,995 for up to 560ml. The volume and treatment plan should still be based on individual anatomy, goals, medical history and suitability.
In this guide, we explain what surgical and non-surgical BBLs involve, how they differ, what changes they may create, recovery, recognised risks and current Deep Aesthetics pricing.
What Is a BBL?
BBL stands for Brazilian butt lift.
Traditionally, the term refers to a cosmetic surgical procedure in which fat is removed from another area of the patient’s body through liposuction, processed and transferred into the buttocks. The aim is usually to increase volume, improve projection and change the proportions between the buttocks and surrounding areas.
The term is now also used for non-surgical or liquid BBL procedures. These treatments use injectable filler rather than the patient’s own fat.
A Brazilian butt lift should not be confused with a surgical buttock lift. A buttock lift generally removes or repositions loose skin and tissue, whereas a traditional BBL mainly adds volume through fat transfer.
How Does a Surgical BBL Work?
A surgical Brazilian butt lift generally involves several stages:
- A plastic surgeon assesses the patient, their health and the amount of available donor fat.
- Fat is removed from areas such as the abdomen, flanks, hips or thighs using liposuction.
- The removed fat is processed.
- Selected fat is transferred into the buttock area.
- Recovery involves both the liposuction areas and the fat-transfer site.
The procedure may therefore change more than the buttocks. Removing fat from surrounding areas can also alter the waist, hips or thighs, affecting the overall silhouette.
Not all transferred fat remains permanently. Some may be reabsorbed during healing, and the eventual appearance can also change with ageing or significant weight fluctuation.
A surgical BBL is a major cosmetic procedure with potentially serious complications. Fat entering a blood vessel can travel to the lungs and cause a pulmonary fat embolism, which is a medical emergency.
What Is a Non-Surgical BBL?
A non-surgical BBL, sometimes called a liquid BBL, uses injectable filler to alter buttock volume and contour. It does not involve liposuction or surgical fat transfer.
Depending on anatomy and the agreed treatment plan, filler may be used to:
- Add selected volume
- Improve contour
- Address visible asymmetry
- Increase upper or lateral fullness
- Create subtle to moderate projection
- Restore some volume following ageing or weight change
The Deep Aesthetics service page currently describes its procedure as using hyaluronic-acid filler. It also states that the amount used can be adjusted according to the volume and shape being considered.
A filler-based BBL should not be viewed as a smaller form of surgical BBL surgery. The material, process, scale of change, recovery, duration and complication profile are different.
Non-surgical also does not mean risk-free. Injectable filler can cause infection, nodules, migration, tissue injury and vascular complications.
Surgical vs Non-Surgical BBL
| Feature | Surgical BBL | Non-Surgical BBL |
| Material used | Patient’s own fat | Injectable filler |
| Fat removal | Liposuction required | No liposuction |
| Incisions | Surgical incisions | Injection or cannula entry points |
| Anaesthesia | Usually surgical anaesthesia | Depends on the treatment and clinic protocol |
| Typical result | Potentially larger-volume change | Usually subtle to moderate contour change |
| Recovery | Surgical recovery involving donor and treatment areas | Usually shorter, but not necessarily zero downtime |
| Longevity | Can last for years but changes with ageing and weight | Temporary and dependent on the product and patient |
| Reversibility | Transferred fat cannot simply be dissolved | Some HA fillers may be treated with hyaluronidase, but complete or simple reversal cannot be guaranteed |
| Main risks | Fat embolism, bleeding, infection, wound problems and anaesthetic complications | Infection, lumps, migration, vascular complications, tissue injury and inflammatory reactions |
Neither option is automatically right for every patient.
Suitability depends on the desired amount of change, available donor fat, overall health, existing anatomy, recovery tolerance, expectations and individual risk assessment.
What Can a BBL Change?
A BBL may be used to alter:
- Buttock volume
- Projection
- Upper or side fullness
- Symmetry
- Contour
- Proportion with the waist, hips or thighs
A filler BBL may suit someone seeking a selected contour change without liposuction, but it may not create the same scale of volume change as surgical fat transfer.
A BBL also cannot guarantee a particular celebrity body shape. Results are limited by anatomy, tissue quality, treatment volume and what can be achieved without creating unreasonable risk.
Exercise may develop the gluteal muscles, but it does not reproduce the effects of transferring fat or placing filler. Readers comparing other ways to reshape specific areas can review the available body contouring options.
What Happens During a Filler-Based BBL?
The exact process varies, but the general patient journey may include:
- Consultation and medical-history review
- Assessment of shape, proportions, asymmetry and goals
- Discussion of the proposed product, volume, expected change and risks
- Preparation and appropriate pain management
- Controlled filler placement
- Immediate assessment and aftercare guidance
- Follow-up when clinically appropriate
Appointment length and discomfort vary according to the volume used, treatment plan and individual response.
A consultation should also establish exactly which filler is being proposed, why it is being used for that area and what plans are in place if a complication occurs.
What Results Can You Expect?
Changes from filler placement may be visible soon after treatment, although initial swelling can affect how the area looks.
Possible changes include:
- Increased fullness
- A rounder contour
- Improved symmetry
- Selected projection
- Better balance with surrounding body contours
The final result should not be judged while significant swelling remains.
The amount of change depends on the patient’s starting anatomy, the volume used and the agreed treatment plan. More filler does not automatically create a better or safer outcome.
Some patients may consider maintenance or further treatment later. Longevity depends on the product, volume, metabolism, activity and individual treatment plan. The Deep Aesthetics website currently contains differing duration statements, so one fixed result period should not be guaranteed.
Recovery and Aftercare
A filler-based procedure usually has a different recovery profile from surgical fat transfer, but it can still cause short-term effects.
These may include:
- Swelling
- Bruising
- Tenderness
- Redness
- Firmness
- Temporary unevenness while swelling settles
Your recovery may depend on the product, treatment volume, placement, individual healing and whether a complication develops.
Follow the personalised aftercare instructions provided by the treating clinic. Contact the clinic promptly if symptoms are becoming more severe rather than settling.
What Are the Risks of a BBL?
Both surgical and filler-based BBLs carry risks. Their complications are different, but either procedure can cause serious harm.
Surgical BBL risks
Possible surgical risks include:
- Fat embolism
- Blood clots
- Bleeding
- Infection
- Fat necrosis
- Fluid collection
- Wound-healing problems
- Unevenness or asymmetry
- Anaesthetic complications
- Revision surgery
- Death in rare severe cases
One of the most serious risks is pulmonary fat embolism. This can occur when transferred fat enters a blood vessel and travels to the lungs.
Filler-based BBL risks
Possible filler-related risks include:
- Swelling, bruising and pain
- Infection or abscess
- Lumps or nodules
- Filler migration
- Inflammatory or allergic reactions
- Uneven contour
- Vascular blockage
- Skin or tissue damage
- Medical or surgical correction
- Serious systemic complications in rare cases
The US Food and Drug Administration identifies unintended injection into a blood vessel as the most concerning general filler risk because it can block blood supply and cause tissue death or other serious complications. It also warns against filler use for buttock enlargement in the United States; that is US regulatory guidance rather than a statement of UK law.
Seek immediate medical help for breathing difficulty, collapse, neurological symptoms, unusual skin-colour changes, severe or rapidly worsening pain, or signs of a serious infection.
Who May Not Be Suitable?
Treatment may need to be postponed or avoided when there is:
- Active infection or damaged skin in the area
- A relevant allergy or previous filler reaction
- A bleeding or clotting disorder
- Certain immune or healing conditions
- Relevant medicine use
- Pregnancy or breastfeeding
- A significant untreated medical condition
- An inability to follow aftercare
- Expectations that cannot reasonably be met
Body-image concerns may also need careful assessment before treatment is considered.
This is not a complete contraindication list. Disclose your medical history, medicines, allergies and previous cosmetic procedures during consultation.

Conclusion: Which Type of BBL Is Right for You?
What is a BBL? It is a buttock-augmentation procedure that may use either surgical fat transfer or injectable filler.
A surgical BBL combines liposuction with fat transfer and may create a larger change, but it involves surgical recovery and potentially severe risks. A non-surgical BBL uses filler and usually aims for a more selected contour change, but it also carries recognised risks and limitations.
Deep Aesthetics offers the filler-based option rather than surgical fat transfer.
The appropriate choice depends on your anatomy, health, goals, recovery tolerance and individual risk assessment. A consultation should clarify what is being proposed, the product or procedure involved, likely limitations, costs and complication plan before you decide.

Frequently Asked Questions
What does BBL stand for?
BBL stands for Brazilian butt lift. Traditionally, it refers to surgery that transfers fat from another area of the patient’s body into the buttocks. The term is now also used for non-surgical or liquid BBL procedures that use injectable filler instead of fat.
Is a BBL surgery?
A traditional Brazilian butt lift is surgery because it involves liposuction and fat transfer. A non-surgical or liquid BBL uses filler and does not involve surgical fat harvesting. However, it is still a medical procedure with recognised risks and should not be described as risk-free.
How long does a non-surgical BBL last?
There is no guaranteed duration that applies to every filler BBL. Longevity depends on the product, volume, metabolism, activity, anatomy and individual treatment plan. Maintenance or further treatment may be considered, but the likely duration should be discussed using information for the exact product being proposed.
Is a non-surgical BBL safe?
A non-surgical BBL carries recognised risks, including infection, lumps, migration, tissue injury and vascular complications. Appropriate medical assessment, clear product information, informed consent and access to complication management are important before treatment is undertaken.
How much is a BBL at Deep Aesthetics?
Deep Aesthetics currently displays a non-surgical BBL filler package at £2,995 for up to 560ml, reduced from a displayed previous price of £4,000. Pricing and promotional offers can change, and not every patient will need or be suitable for the maximum volume.
