This case features an 18-year-old woman who underwent full-circumference arm liposuction followed by Condensed Rich Fat (CRF) breast augmentation (primary session) with a 3-month follow-up.

Fat was harvested only from her upper arms, with 173 cc injected into the right breast and 190 cc into the left, resulting in an approximately 1–1.5 cup size increase.

By sculpting a sharp shoulder line, her upper body silhouette was refined into a beautifully balanced contour.

The Challenge of Fat Grafting in Slim Patients

For naturally slim individuals, even the most precise liposuction may yield limited fat volume (often less than 300 cc per side).

To achieve optimal results, surgeons can consider the following strategies:

• Harvesting fat from multiple donor areas such as the thighs or abdomen.
• Performing secondary or tertiary injections to gradually enhance volume and retention.
• Using Condensed Rich Fat (CRF) to purify and concentrate viable fat cells, improving graft survival.

These methods allow surgeons to achieve the most natural possible results, even when fat availability is limited.

Fat Survival and Its Biological Mechanism

On average, 30–40% of the injected fat survives after a fat graft breast augmentation. The survival rate depends on several key factors:

• Harvest technique: Low-pressure aspiration minimizes cellular trauma.
• Fat processing: Centrifugation removes impurities, oil, and excess fluid.
• Injection depth and dispersion: Multi-layered injection into subcutaneous, subglandular, and intramuscular planes enhances vascular contact.
• Postoperative care: Avoiding excessive compression and maintaining oxygenation promotes new blood vessel formation.

CRF technology refines these steps to maximize graft purity and viability, leading to higher long-term stability and smoother results.

Comparing Fat Grafting and Hybrid Augmentation

Each breast augmentation method has distinct strengths and limitations:

At AVAN TOKYO GINZA LIPOSUCTION CLINIC, we often recommend hybrid augmentation for patients seeking both natural texture and visible volume.

Summary

Fat graft breast augmentation is ideal for patients who value natural softness and anatomical harmony, but outcomes depend heavily on fat quality, vascular supply, injection technique, and postoperative care.

At AVAN TOKYO GINZA LIPOSUCTION CLINIC, our surgeons specialize in both liposuction and advanced fat grafting.

By integrating anatomical precision with artistic contouring, we strive to achieve maximal graft retention and beautifully natural results.

If you wish to create a soft, natural, and balanced breast shape that complements your figure, fat graft or hybrid augmentation may be your ideal choice.
