PAMI Fat Grafting — Clinical Area Guide
PAMI Fat Grafting: Evolving Standards
and Areas That Still Require Extra Care
As techniques advance, the range of treatable areas continues to grow — but so does our understanding of which areas demand a more precise, nuanced approach. Cellon Clinic gives you an honest breakdown from a PAMI Fat Grafting clinical perspective.
What Does It Mean for Transplanted Fat to Survive?
Fat grafting is far more than simply moving fat from one place to another. For transplanted fat cells to survive in their new location, they need a supply of oxygen and nutrients from the surrounding tissue. This process is medically known as "engraftment," and until engraftment is established, the transplanted fat cells remain in a highly vulnerable state.
The first 72 hours after the procedure are the critical window for engraftment. During this period, the fat cells rely on exudate for hydration while waiting for the surrounding capillaries to connect. The faster new blood vessels form, the higher the engraftment rate. In areas with insufficient vascular supply, a significant portion of the transplanted fat may be reabsorbed or undergo necrosis.
Each area of the face differs in vascular density, tissue thickness, and frequency of muscle movement. Because these three factors determine the engraftment environment for transplanted fat cells, results can vary in texture from one area to another — even when the same technique is applied on the same day.
A large share of dissatisfaction with fat grafting outcomes stems from cases where these differences were not adequately discussed before the procedure. At Cellon Clinic, it is our standard practice to explain the engraftment conditions for each area to patients from the very first consultation.

Areas Favorable for Fat Survival — and Areas That Demand Greater Precision
Here's a breakdown of each facial zone from the perspective of fat graft survival conditions. When we say an area is "demanding," we don't mean it's impossible — it means it requires more refined technique and realistic expectation-setting.
"When patients already understand that each facial zone has its own graft survival dynamics, the quality of the consultation changes entirely. The clearer they are about what results they want and where, the more precisely we can plan both the technique and the volume."
— Dr. Kang Seung-hoon, Chief Director, Cellon ClinicHow PAMI Fat Grafting Takes a Different Approach
The core of PAMI (Processed Autologous Microfat Injection) lies in maximizing the quality of the graft material itself. In areas where the engraftment environment is unfavorable, the cellular viability and particle size of the graft material become the key variables that determine the outcome.
Uniform Particle Size Through Micro-Separation
Harvested fat is precisely separated using a specialized filter to minimize particle size. Smaller particles increase the contact surface area with surrounding tissue, enabling faster neovascularization. This is especially critical in areas with limited space and thin skin, such as the under-eye region.
Preserving Live Cells and Stem Cell Ratio
Physical stress during harvesting and processing is minimized to preserve as many adipose-derived stem cells (ADSCs) and stromal vascular fractions (SVF) as possible. A higher ratio of viable cells increases the likelihood that post-engraftment volume remains stable over time.
Layer-by-Layer Precision Injection for Area-Specific Design
Vascular distribution and tissue characteristics differ across anatomical layers — above the periosteum, within the subcutaneous fat layer, and below the dermis. In PAMI Fat Grafting, graft volume and particle size are tailored to the specific characteristics of each layer, aiming for natural volume integration.
Leveraging Regenerative Medicine Infrastructure
Cellon Clinic is a Cheongdam Designated Advanced Regenerative Medicine Hospital certified by the Ministry of Health and Welfare. Going beyond standard fat grafting, we apply protocols that support a stem cell-based regenerative environment to comprehensively optimize conditions for post-graft engraftment.
Even with PAMI Fat Grafting, achieving complete satisfaction from a single session can be difficult in areas with unfavorable engraftment conditions. For more challenging areas — such as the under-eye or around the lips — a staged approach is often safer and more effective: starting with a conservative graft, assessing the result, and adding more if needed. At Cellon, we make sure to walk patients through this process thoroughly during the consultation.
How Cellon Clinic Plans Your Fat Grafting — Zone by Zone
In-Depth Aging Pattern Analysis
Rather than simply noting that an area "looks hollow," we assess precisely which fat compartments have lost volume at which tissue depth, and evaluate the degree of skin laxity and skeletal changes. A thorough analysis is what allows us to design the right treatment zones and graft volumes for each individual.
Zone-by-Zone Graft Survival Consultation
We walk you through the realistic engraftment conditions for each target area and set honest expectations. If a particular zone is technically challenging, we'll discuss how many sessions may be needed — and whether an alternative approach might actually serve you better.
Harvest Site & Processing Method Selection
Fat density and cellular composition vary depending on where it's harvested — abdomen, thighs, flanks, and so on. We factor in the characteristics of the recipient site and the desired texture of the graft to customize both the harvest location and the processing technique.
Post-Procedure Engraftment Support
The 72 hours immediately following the procedure are the most critical window for graft survival. We provide detailed aftercare instructions timed to this period, and when appropriate, complement the procedure with regenerative medicine-based adjunct treatments to optimize the engraftment environment.
