Shall we get a sense of the graft survival rate with the numbers first?
The key to facial fat grafting ultimately lies in "how well the transplanted fat survives and takes root." Conventional fat grafting has a relatively low survival rate of around 20–40%, often requiring repeated procedures. In contrast, stem cell (SVF) fat grafting involves injecting fat-derived cell components (SVF) extracted from fat along with high-purity fat, and is known to improve the survival rate to 70–80%. To use a tree analogy, it is like helping the roots (blood vessel formation aided by SVF) take root along with the branches, rather than just planting the fat.
How does the approach differ depending on the body part?
Even with the same stem cell (SVF) fat graft, the graft depth and injection method are designed quite differently depending on the facial area. For the forehead, since it is a relatively flat and wide area that needs to be filled, it is common to graft in multiple layers, dividing the fat into shallow and deep layers. Since concentrating too much into a single layer can result in an uneven surface, layered distribution is particularly important in this area.
Facial Fat Grafting: How Is It Actually Performed?
Step 1. Analysis of Facial Volume and Structure Each part of the face, such as the forehead, cheekbones, and jawline, possesses unique anatomical characteristics. The SC301 precisely analyzes the volume, symmetry, and lines of the entire face through 3D scanning and conducts a thorough consultation lasting at least 30 minutes. Step 2. Fat Harvesting Unwanted fat is gently harvested from areas such as the abdomen or thighs.
What does 3D scanning actually show?
To explain further for those who are curious, 3D scanning is different from simply taking a photograph. It measures the contours of the facial surface in three dimensions, allowing you to numerically verify differences in volume between the left and right sides, the degree of depression in specific areas, and the asymmetry of the overall lines. Based on this data, you can simulate in advance how much fat is needed in each area, which helps create predictable results rather than relying on intuition for design.
How can side effects be prevented?
While stem cell (SVF) fat grafting offers a higher engraftment rate than conventional methods, it is not entirely free of side effects. Typical side effects include the expulsion of unengrafted fat from the body or calcification, where the fat combines with surrounding tissues to harden. These risks depend heavily on the engraftment rate and the experience of the medical team; therefore, it is particularly important to verify the following three criteria when undergoing SVF fat grafting.
