Fat Grafting Breast Augmentation:Why Some Breasts Retain Fat Better Than Others2026.01.24
One of the most common questions patients ask about fat-graft breast augmentation is:
“How much of the fat will actually stay?”
While many patients achieve about 1.5 cup sizes of natural enhancement, the truth is that fat retention varies significantly depending on the individual breast characteristics.
At AVAN TOKYO Ginza Liposuction Clinic, we carefully evaluate these factors during consultation to design a safe and effective grafting strategy tailored to each patient.
Breasts That Show Good Fat Retention
✔ 1. Good Skin Elasticity
When the skin has enough flexibility and space, the grafted fat can settle comfortably without excessive pressure.
Even patients with slight ptosis often have more skin allowance, which actually supports better retention.
✔ 2. Adequate Tissue Volume (fat + glandular tissue)
Breasts with more existing tissue have better blood supply, which is essential for fat survival.
If the breast has a good natural shape and volume, the newly grafted fat integrates more smoothly.
✔ 3. BMI above 19
Interestingly, fat grafting is the opposite of liposuction—
patients who naturally tend to gain weight often have more resilient fat cells, which survive better after transfer.
Breasts That Tend to Have Lower Retention
Retention may be reduced when:
- The skin is very tight
- There is very little natural breast tissue
- BMI is very low (very slim body type)
In these cases, we adjust the injection planes, total volume, and pressure balance to minimize risks and maximize the natural outcome.
**Clinical Example:
21-year-old, Arm & Thigh Liposuction → Fat Grafting Breast Augmentation (3 Months Post-op)**
This patient received 340 cc on the right / 330 cc on the left, which is relatively generous.
She had:
- Good skin elasticity
- Adequate breast tissue
- Favorable tissue compliance
As a result, she achieved excellent retention and a natural 1.5+ cup size increase even at 3 months post-op.

Fat Grafting Is Not “One Size Fits All”
Fat-graft breast augmentation is not a simple formula of
“inject X cc = gain Y cup sizes.”
Fat survival depends on:
- Skin elasticity
- Breast tissue quality
- Body type
- Circulation
- Lifestyle and postoperative care
- And the surgeon’s technique
This is why AVAN TOKYO performs a detailed preoperative assessment to estimate your individual retention potential.
