Many people believe that once fat has been transferred to the breasts, it will simply remain there permanently.

In reality, the long-term survival of transferred fat depends not only on surgical technique, but also on how you care for yourself after surgery.

At AVAN TOKYO, we believe that breast augmentation does not end in the operating room. Postoperative care is an essential part of achieving natural, long-lasting results.

Transferred Fat Does Not Survive Immediately

Fat grafting involves transplanting your own fat cells into the breasts.

Immediately after surgery, these fat cells have not yet established their own blood supply.

To survive permanently, they must receive oxygen and nutrients through the formation of new blood vessels, a process known as angiogenesis.

Although this process begins soon after surgery, it generally takes up to three months for the transplanted fat to become fully integrated into the surrounding tissue.

This is why we often describe the first three months as the period when your new breast tissue is “growing.”

Compression Can Reduce Fat Graft Survival

Healthy blood flow is essential for newly transferred fat cells.

Excessive pressure on the breasts may reduce blood circulation during this critical healing period.

For this reason, during the early postoperative phase we recommend avoiding:

• Tight underwire bras
• Compression bras that place excessive pressure on the breasts
• Frequent squeezing or firm massage of the breasts

Internal pressure is also important.

Injecting an excessive amount of fat into a limited space can increase tissue pressure, reducing blood flow to the transplanted fat and increasing the risk of fat resorption or fat necrosis.

At AVAN TOKYO, our goal is not to inject the largest possible volume of fat.

Our priority is to create the best possible environment for long-term fat survival.

We Recommend Wireless Bras for the First 1–1.5 Months

Following fat grafting or Hybrid Breast Augmentation, we generally recommend wearing a wireless bra for approximately 4–6 weeks.

Wireless bras provide gentle support while minimizing localized pressure on the newly grafted tissue.

The appropriate type of bra and the duration of use may vary depending on each patient’s recovery, and we provide individualized guidance during follow-up visits.

Case Study

This patient underwent:

• Revision arm liposuction
• Revision thigh liposuction
• Hybrid Breast Augmentation

She had previously undergone:

• Fat graft breast augmentation
• Motiva Mini 200 cc silicone implants placed in the subglandular plane

For this procedure, additional fat grafting was performed:

• Right breast: 100 mL
• Left breast: 80 mL

Throughout her recovery, she carefully followed our postoperative recommendations, including:

• Wearing a wireless bra
• Maintaining a high-protein diet
• Paying close attention to overall nutrition, including adequate protein intake

As healing progressed, the transition from the upper arms to the collarbone, décolletage, and breasts became noticeably smoother and more balanced, creating an elegant upper-body silhouette.

Our Philosophy at AVAN TOKYO

Successful fat grafting is not determined by how much fat is injected.

What truly matters is:

• Where the fat is placed
• How much fat is injected
• Which tissue layers receive the graft
• How well the transplanted fat is protected during healing

Using anatomy-based techniques, we carefully distribute small amounts of fat throughout multiple tissue planes to maximize blood supply and promote long-term graft survival.

Our commitment extends beyond surgery.

We continue to support each patient throughout recovery because we believe postoperative care is just as important as the operation itself.

Frequently Asked Questions

When can I wear an underwire bra again?

In most cases, we recommend wearing a wireless bra for approximately 4–6 weeks after surgery. Your surgeon will advise you based on your individual healing progress.

Does nutrition affect fat graft survival?

Yes.

Adequate nutrition, particularly sufficient protein intake, supports wound healing and tissue repair. Maintaining a balanced diet is an important part of recovery.

Should I massage my breasts after fat grafting?

During the early healing phase, we generally do not recommend applying strong pressure or massage to the breasts. Appropriate postoperative care varies depending on the stage of healing.

Message From Our Surgeon

Fat graft breast augmentation is not simply about increasing breast volume.

It is about helping transplanted fat survive, integrate, and become living tissue.

At AVAN TOKYO, we combine meticulous surgical technique with personalized postoperative care to optimize long-term fat survival.

Our goal is not only fuller breasts, but also a naturally beautiful transition from the upper arms to the shoulders, décolletage, and breasts.

Because truly beautiful results are achieved through both excellent surgery and thoughtful recovery.

Fat graft survival and healing vary between individuals. Treatment recommendations are always individualized based on each patient’s anatomy and recovery.
