Autologous fat is a material often used for face, breast, buttocks and leg correction. Personally speaking, it is a highly recommended autologous material, its advantages are mainly in 3 aspects: Autologous fat is the body’s own tissues, taken from their own body, very suitable for those who reject foreign materials. The fat contains a lot of stem cells, which can make the skin more delicate after filling, and at the same time lighten the color spots, reduce pores, and improve the skin quality. After 2 to 3 fillings, the fat will be permanently viable, unlike other materials that need to be replenished frequently. However, there are always two sides of the coin, there are advantages and disadvantages, and the main risks of autologous fat filling are: For all surgeries, there is a possibility of infection. For example, if the filler hits a blood vessel and punctures it, causing localized bruising and bleeding. However, since the needle used for filling is blunt, normal tissues usually only bleed slightly. In the case of a minor localized infection, immediate dressing changes and rinses and systemic antibiotics are needed to keep the infection localized. Localized nodule problems. Autologous fat is not filled once to become viable, usually need to fill two to three times. Some candidates in order to improve the survival rate, require a single filling volume is relatively large, if the overfilling of the local blood circulation is not well established, the fat did not survive, the normal tissue will not survive the parcel of tissue, phagocytosis by the phagocytes discharged from the body after phagocytosis. If the package can not be phagocytosis, the formation of nodules, the size of similar to soybean, there are huge such as walnuts, commonly found in breasts, buttocks and other large areas of filling parts. Surface unevenness. This type of problem requires the doctor to do gradual multi-point injection when injecting, slowly tunneling. Where more and where less, you need to design and draw the specific position before the operation, operate in strict accordance with the position during the operation, and then carefully check after the operation is completed, check the completion of the next stage. The problem of survival rate. Some patients complained to me that the autologous fat filler did not survive even after 4 times, and asked me the reason. First of all, is there a problem with the fat, and is the blood circulation of the localized filler good? Secondly, whether the doctor’s operation is appropriate and whether the purification process is proper. In my experience, there are very few candidates who have not survived 4 to 5 times, and there are also candidates who have survived all at once, which is probably comparable to their chances. Skin necrosis. Localized skin necrosis can occur if there is too much localized filling, blocking blood circulation and compressing blood vessels, but it is very rare in practice. Fat embolism problem. In mild cases, there may be loss of vision, and in severe cases, it may lead to blindness. If the fat filler enters the blood vessels and eventually the cranium, it can cause limb impairment on one side or even death. There are also a few things I can tell you about how you can fill more safely: Inject without resistance, if there is a little bit of resistance when you push the injection, be sure to look at the exact cause. Multi-point, multi-level injections. Some candidates have seen footage of me doing lipofilling in videos where my hands are constantly shaking. So they leave me a message asking if it is because Prof. Lu Benglun is old enough to do the surgery with obvious hand shaking problem. In fact, it is not at all, filler injection is the need to back off the needle little by little injection, 1 ml is best to be divided into 60 points of injection, in the absence of resistance in order to ensure the safety of the injection. Finally, to say something off topic, to do cosmetic surgery such as non-essential surgery, be sure to study the pros and cons of the surgery, what they can get, and how much risk they will take, they can accept the worst consequences before going to surgery. When looking for a doctor, make sure you find one you can trust. Instead, you should run to whichever hospital you can get a discount or a big promotion for your surgery. Without the most basic understanding of the doctor, not to mention mutual trust, from the first day of the swelling period began to doubt whether the doctor to do bad for themselves, which is often the doctor’s biggest headache. More interviews, more research, more comparisons, find a doctor who shares your aesthetic values, don’t hold your breath before surgery, and be brave enough to refuse surgery if it doesn’t match your doctor’s aesthetics. For me personally, I don’t agree with the mesh face and I just never go for it.
