Fat transfer: Looking for a natural volume?
Looking for a larger, more rounded buttock? Unsatisfied with your breast size? Need a solution for facial volume loss? Consider fat transfer, a natural method to enhance and contour your face and body. Fat grafting, a common soft tissue augmentation technique, involves harvesting excess fat through liposuction and injecting purified fat grafts into desired areas.
These fat cells come from your own excess fat in areas like the belly, flanks, or thighs.
The fat is processed and purified before being injected into the desired area to increase volume. This technique is commonly employed in facial rejuvenation, scar treatment, natural breast augmentation without implants, and the Brazilian butt lift (BBL) procedure.
However, it is important to note that only a portion of the transferred fat will survive in the new location. So, let’s check how to maximize fat survival rate after fat transfer treatment.
What does fat survival (engraftment) mean?
After a fat transfer procedure, the survival of the transferred fat cells, also known as engraftment, plays a crucial role in determining the longevity and effectiveness of the results. Engraftment is the process by which harvested fat cells make their way (homing) to other fat cells existing in injected area, where they can find optimal conditions to survive and proliferate.
Can you grow more adipose tissue?
Fat cell number remains constant in adults, regardless of a significant turnover (approximately 10% of fat cells annually) when body weight is stable. Decreasing body weight only affects the size of fat cells, making them smaller. However, increasing body weight leads to an increase in both the size and number of fat cells in adults.
How long do fat survive after transfer?
Fat grafting is a procedure where surgeons extract fat through gentle liposuction and inject it into another area. Despite using delicate techniques, around 30% ~50% fat does not survive and is absorbed by the body within 6-12 months of the procedure.
Does fat grow back after fat transfer?
Fat does not regenerate after fat grafting or transfer, but the surviving transferred fat cells become permanent and act like other fatty tissue in the body. Therefore, the transferred fat will be affected by weight changes, hormonal fluctuations, etc. To enhance fat graft survival during the recovery period, it is important to be aware of potential failure points and take necessary precautions. Whether you’re undergoing a Brazilian butt lift, facial fat grafting, or breast autologous fat grafting.
Methods for helping fat to survive after fat transfer
The practice has demonstrated that graft volume retention of up to 80%+ can be achieved when minimizing trauma and maximizing recipient site nutrition and oxygenation. Here are some methods to maximize fat survival following fat transfer:
Eat healthy fats
Consuming healthy fats, such as walnuts, almonds, extra virgin olive oil, salmon, and avocado as well as an overall healthy diet can help to optimize your fat transfer results. Nutrient-rich foods will give your body everything it needs to optimize the fat graft microenvironment and ensure survival of the newly transferred fat.
Staying well hydrated helps with in the healing process and increases the chances of the transferred fat survival. Remember to stay away from empty calories in soft drinks and avoid excessive caffeine, salt, and sugar. Water is the best way to stay hydrated. You can add lemons or lime to your jug of water if you want some flavor.
Hold off on strenuous exercise
For the first 8 weeks after fat transfer procedures like Brazilian butt lift, natural breast augmentation, and facial fat transfer, you should avoid doing any strenuous or high-impact exercises that could potentially put pressure on the treated area. It is okay to do light exercises such as walking. After a couple of months, the fat tissue grafted will have settled and you can go back to more robust exercise sessions.
Fresh Clinic Fat Survival Secret
Transplant and engraftment of the harvested fat is performed through a small skin incision that corresponds to the diameter of the cannula being used. Smaller cannulas will minimize recipient site trauma; however, this must be weighed with the potential sheer force traumatic risk to the harvested fat.
Bleeding and hematoma formation are potential issues for the recipient, which can negatively affect the retention and oxygen diffusion of the graft. However, Dr. Hong from Fresh Clinic has a remarkable 15-year reputation and experience in liposuction. He possesses the knowledge of safe fat harvesting techniques and minimal cell damage during injection. Dr. Hong practices the use of autologous platelet-rich plasma (PRP) or Stem Cells to enhance the survival rate of fat.
PRP has a significant impact on the viability of autologous fat grafts, enhancing their survival post-injection. It is derived from a small blood sample and contains numerous growth factors, including vascular endothelial growth factor.
These growth factors support the transplanted fat by aiding its resistance to stress during the initial days and facilitating proper arrangement within the surrounding extracellular matrix
Furthermore, PRP stimulates formation of new blood vessels, which is essential for establishing a robust blood supply crucial for optimal fat survival after the transfer surgery.
Dr. Hong employs various advanced methods, such as PRP and Stem Cell therapy, along with specialized equipment like the Harvest-Jet 2, for grafting procedures. Additionally, different sizes of cannulas are utilized for precise engraftment, varying based on the recipient site location. Specifically for facial grafting, smaller caliber cannulas (1 mm) with different tip shapes, diameters, and lengths are utilized. This meticulous approach significantly minimizes fat damage during the transfer process.
