Fat Grafting for Corrective Procedures: Fixing Uneven Contours, Botched Liposuction and Dented Scars

Fat grafting can correct botched liposuction & gynecomastia surgery, uneven contours & dented scars using your own fat. Learn how it works.

Fat grafting for corrective procedures

Table of Contents

Fat grafting for corrective procedures uses your own fat to fill in dents, hollows and uneven areas left by botched liposuction or gynecomastia surgery, injury, or accident. Fat is harvested, purified and injected into the affected area, sometimes alongside corrective liposculpture, to restore a smoother, more even contour.

Key Takeaways

  • Fat grafting can fix botched liposuction and gynecomastia surgery. Fat grafting, with or without corrective liposculpture, can even out imperfections and restore a normal-looking contour.
  • Poor technique causes uneven results. Multiple unnecessary incision points and incorrect techniques can leave an asymmetrical body shape and uneven skin texture, which is why a doctor’s experience matters so much.
  • It can also treat dented scars. Scars from accidents or surgery can sometimes be treated effectively with minor surgical correction using fat grafting, though results depend on the scar and need an in-person assessment.
  • Your own fat is the filler. Because the tissue is yours, it integrates into surrounding areas for a natural look and feel.
  • Choose your doctor based on experience, not price. For corrective work, look for MOH accreditation, decades of experience in liposuction and fat grafting, relevant technique training, and clear communication about realistic results.

What are corrective fat grafting procedures?

Corrective fat grafting is the use of your own fat to repair contour irregularities and tissue loss. Unlike enhancement procedures, the goal here is restoration: making an area look normal again.

It is commonly used for:


Concern How fat grafting helps
Botched liposuction Evens out uneven, asymmetrical body shape and skin texture, most often on the abdomen and thighs.
Dented or atrophic scars Fills uneven scar tissue through minor surgical correction
Botched gynecomastia surgery Fills in crater in the male chest

Why does liposuction go wrong?

Liposuction is more than removing fat. It calls for scientific knowledge and finesse, and that competence comes only with years of experience.Poor outcomes often follow when a doctor makes multiple unnecessary incision points or applies incorrect techniques. The result can be an uneven, asymmetrical body shape and skin texture.

Common signs of a poor liposuction result

  • Visible dents, ridges or waviness
  • Asymmetry between the left and right sides
  • Uneven skin texture
  • Over-treated or under-treated areas

Can fat grafting fix botched liposuction?

In many cases, yes. Dr Ivan Puah explains that the abdomen and thighs are the two most common areas affected by botched jobs. He says that “fat grafting with or without corrective liposculpture will help to even up these imperfections and make them look normal again.”

The approach depends on the problem:

  • Fat grafting alone: Fat is placed into over-treated hollows or depressions to restore volume.
  • Fat grafting for corrective liposculpture: Fat is refined or removed from high spots while grafting fills the low spots, balancing the overall contour.

Suitability depends on the extent of the irregularity and the amount of donor fat available. An in-person assessment is needed.

How does corrective fat grafting work?

  1. Assessment: The doctor evaluates the irregularity, symmetry and available donor fat.
  2. Harvest: Fat is removed from a donor area using liposuction techniques such as Vaser liposuction.
  3. Purify: The harvested fat is processed.
  4. Inject: The fat is placed precisely into the dented or depleted areas.
  5. Integrate: The fat cells integrate into the surrounding tissue for a natural feel and look.

Can fat grafting treat dented scars?

Yes, in suitable cases. People who have had skin and tissue injuries from accidents or surgery may be left with dented scars. 

Dr Puah says, “Uneven or atrophic scar tissues on the skin can sometimes be treated effectively with minor surgical correction with fat grafting.”

The word “sometimes” matters. Results depend on the type, depth and location of the scar, so a consultation is essential.

Can fat grafting correct botched gynecomastia surgery?

Yes. Fat grafting can be used to fill in the indented appearance from crate deformity, asymmetry or a sunken chest, to create a natural-looking chest contour.

Why use your own fat for correction?

  • Natural look and feel: The tissue integrates into surrounding areas.
  • Versatile shaping: Fat grafting allows flexible, tailored correction.
  • Repeatable: Multiple sessions are possible to further improve the results.

How do you choose a doctor for corrective surgeries using fat grafting?

Correction is harder than a first-time procedure, so experience matters more. Don’t choose by price alone. Look for:

  • MOH accreditation to perform liposuction.
  • Years of experience in liposuction, body contouring, fat grafting and revision work, with a good track record.
  • Relevant training, such as Vaser liposuction and laser lipolysis.
  • Clear communication. The doctor should understand your concerns and explain realistic, achievable results in detail.
  • An aesthetic eye. Dr Puah describes natural results as 70% art and 30% science.

Dr Ivan Puah is accredited by the Ministry of Health to perform liposuction and has over 20 years of surgical experience. He chairs the Lipo Peer Review Committee Singapore, trained in Vaser liposuction in Colorado and Argentina, and trained in laser lipolysis in Italy. His proprietary MDC-Sculpt® Lipo technique removes fat, shapes the body and tightens the skin.
