Defyne Plastic Surgery is changing the paradigm of fat grafting with its new EVFT (Enhanced Viability Fat Transfer) technique. EVFT applies biologic preservation science to fat grafting, prioritizing cell protection and viability throughout the processing, which allows for higher fat survival rates and more predictable, natural-looking results compared to traditional fat grafting methods.

Why it matters

For decades, fat grafting has relied on mechanical processing methods that expose fragile fat cells to stress, leading to inconsistent long-term survival. EVFT fundamentally changes this by using a surfactant-based, membrane-stabilizing solution to preserve the structural integrity of fat cells during preparation, allowing for better integration, blood supply, and volume maintenance over time.

The details

EVFT uses a surfactant-based, membrane-stabilizing solution rooted in decades of use across delicate human tissues to preserve the structural integrity of fat cells during preparation. This allows transplanted fat to integrate more effectively, establish blood supply, and maintain volume over time. Traditional fat grafting methods focus on washing or spinning harvested fat, which can damage fat cells and lead to inconsistent long-term survival rates between 30-60%. In contrast, EVFT has demonstrated fat survival rates exceeding 80%, significantly reducing volume loss and variability.

  • Defyne Plastic Surgery introduced EVFT in January 2026.

What they’re saying

“For years, fat grafting has been treated like a mechanical process. But fat is living tissue. If you damage it before transfer, it cannot survive. EVFT applies the same biologic logic we use in other tissue transplants, and the results are fundamentally different.”

— Dr. Oren Tessler, MD, Founder, Defyne Plastic Surgery

“When fat survival becomes predictable, everything changes. We can sculpt with confidence instead of compensating for loss. Patients get results that look natural, age better, and do not require repeated procedures.”

— Dr. Oren Tessler, MD, Founder, Defyne Plastic Surgery

What’s next

Defyne Plastic Surgery plans to continue researching and refining the EVFT technique to further improve fat grafting outcomes.

The takeaway

EVFT represents a significant advancement in fat grafting technology, allowing for more predictable, natural-looking results by prioritizing the preservation of fat cells during the preparation process. This shift from a mechanical to a biological approach could transform the future of aesthetic procedures that utilize fat grafting.
