Revision Brazilian Butt LiftWhy a second BBL is sometimes needed, when it can be done and what it can realistically change

Medically reviewed: Last reviewed by Mr Reza Nassab, FRCS Plast —

Revision BBL is surgery to improve the result of a previous Brazilian butt lift, most often because too much fat was reabsorbed, the buttocks are uneven, there are lumps or dents, or donor areas were over- or under-treated. It is usually considered no sooner than six to twelve months after the first operation, once swelling has settled and the final result is clear. Revision is more complex than a first BBL, and it can improve many problems but cannot always fully correct them.

Why revision is sometimes needed

  • Volume loss: the amount of grafted fat that survives varies, and some people lose more than expected.
  • Asymmetry: fat may survive better on one side, leaving the buttocks uneven.
  • Lumps and firm areas: fat necrosis or oil cysts can form where fat did not establish a blood supply.
  • Irregular donor areas: dents, ridges or uneven contour after liposuction of the abdomen, flanks or back.
  • An unnatural shape: fat placed in the wrong areas can create a shelf, an overly square shape or poor transition to the hips.
  • Weight change: later weight gain or loss can alter the shape achieved.

How long to wait

Swelling can mask the true result for months after a BBL, and fat that is going to be reabsorbed does so over the early period. Most surgeons advise waiting at least six months, and often twelve, before considering revision. This allows scar tissue to soften and gives a clear picture of what has changed. The exception is an urgent problem such as infection, which should be treated promptly by the team who performed the surgery or through NHS services.

What can be improved

Revision surgery may be able to:

  • Add volume: further fat grafting where there is enough donor fat remaining, placed in the subcutaneous layer in line with BAAPS guidance.
  • Improve symmetry: by adding more fat to one side or reducing fullness on the other with liposuction.
  • Smooth irregularities: by releasing tethered areas, redistributing fat or treating donor-site dents with careful fat grafting.
  • Refine the waist and hips: with further liposuction to improve the overall silhouette.

What may be harder to change

Revision has limits. After a previous BBL and liposuction, there may be little fat left to harvest, which restricts how much volume can be added. Scar tissue from the first operation makes the tissues firmer and less forgiving, and grafted fat may survive less well in scarred areas. Loose or sagging skin cannot be corrected by adding fat alone. Hard lumps from non-surgical injections of fillers or other substances can be particularly difficult to treat and may need specialist assessment.

Why revision is more complex

Every revision starts with understanding what was done before. Operation notes from the original surgeon, especially from overseas procedures, are often incomplete or unavailable. Scar tissue alters the normal tissue planes, anatomy may be distorted and blood supply may be reduced. For these reasons, revision operations can take longer, recovery may be slower, and the risks of irregularities, infection and poor fat survival are higher than with a first procedure. Realistic goals are essential.

Surgery after a BBL abroad

Mr Nassab sees patients who had a BBL abroad and are unhappy with the result or have ongoing problems. If you have an active complication, such as an open wound, spreading redness, fever or a collection of fluid, seek medical attention promptly through your GP, NHS 111 or A&E rather than waiting for a cosmetic consultation. Once problems have settled, a planned revision can be discussed. Bring any records you have, including the names of the hospital and surgeon and details of what was done.

The consultation and cost

Mr Nassab will ask about your original surgery, what concerns you most and your weight history. He will examine the buttocks and donor areas, assess scar tissue, lumps and skin quality, and may request imaging such as an ultrasound scan. He will then explain honestly what can realistically be improved. Revision BBL is quoted at consultation because each case is different; for reference, a primary buttock fat grafting (BBL) costs from £12,500. The £150 consultation is separate. Cosmetic surgery is for adults aged 18 and over.

Frequently Asked Questions

How soon after a BBL can you have a revision?

Usually at least six to twelve months, once swelling has settled and the result is clear.

Is revision BBL riskier?

Revision is more complex because of scar tissue and altered anatomy, so some risks are higher than with a first BBL.

Can a BBL done abroad be revised?

Often, yes, once any complications have been treated. Bringing records of the original surgery helps planning.

Can lumps after a BBL be removed?

Some can be improved with surgery or liposuction, but lumps from injected fillers or other substances can be difficult to treat.

What if there is not enough fat left?

Options may be limited. Mr Nassab will explain whether a smaller top-up or contouring of the waist would help instead.
