With Thanksgiving not long past, today’s post starts with a chat about turkeys. Americans named this species directly after a country, which shows how arbitrary Americans can be. The turkey has a colorful head, and the most eye-catching is its chin, yes, colorful and flabby double chin! Flabby face, not only show fat, but also loose skin, looks old years. No matter how much you exercise, it is difficult to have stern lines on a fat face. In order to slim the face, some people seek to grind the jawbone, some people seek to play Botox, some people seek to play lipolysis injection, etc., some people may have to ask, so many methods, in the end, which one is good? In order to answer this question, we need to figure out the three main tissue structures that affect the contours of the face. First is the bone, a rough jawline makes your face appear angular and can easily turn a delicate woman into a hunk, and its corresponding solution is jawline surgery; second is the muscle, an enlarged biting muscle kills a woman’s softness straight away, and this needs to be solved with Botox; and lastly is the fat, which describes the kind of fat distributed in the cheeks of a baby bump, and needs to be solved by buccal fat pad removal surgery. The fat that describes a double chin is distributed in the subcutaneous area at the junction of the jaw and neck. The means to solve this problem are liposuction with immediate effect, but with traditional liposuction, it is easy to have postoperative unevenness because the subcutaneous tissue layer in this area is very thin. Minimally invasive lipolysis, radiofrequency and other means often have limited effect and need to be repeated several times. This has led to minimally invasive fiber optic thermoplastic treatments, which usually achieve excellent results with a single treatment. Fiber optic thermoplasty is also called laser lipolysis, I prefer fiber optic thermoplasty this call, because the double chin to solve the problem of shaping, not just dissolve fat. The real meaning of the thin face is actually full, tight, with a perfect smooth face. Rather than flattening what was just the right amount of fullness in order to slim down, whereas what was sunken becomes even more sunken, which is completely inconsistent with human aesthetics. Under the premise of perfect face shape as a proportion, attention should also be paid to the coordination of the candidate’s facial features, the smoothness of the curvature of the face, and the flatness of the distribution of facial fat. The laser is directly contacted with the fat tissue through fiber-optic delivery, and thermal damage is used to achieve the purpose of lipolysis. The thermal damage effect of laser reduces intraoperative bleeding and postoperative skin ecchymosis, and enhances skin retraction. Through the direct contact of laser with fat tissue, it can be found that the fat cell membrane ruptures and dissolves, the small blood vessels in the fat tissue contract, and the collagen tissue under the skin coagulates. Fiber optic thermoplasty, as a new application technology, has the advantages of less trauma, less bleeding and faster recovery compared to the traditional negative pressure fat suction, and it is easier to operate, and can be used without the auxiliary negative pressure system because the lymphatic system of the human body is able to return a certain amount of dissolved fat. It has unique advantages in the fine operation of the face. Its 1mm thick optical fiber catheter allows the operator to perform finer operation. Through the fiber optic catheter of 1-2mm in diameter, the laser output device acts on the tissues, and during the treatment, you can choose to turn on the laser indicator, which identifies the position of the treatment head, and the indicator can be seen through the skin during the whole treatment process, which allows the operator to grasp the treatment area and carry out fine operation. The future development trend of laser is to develop a highly selective laser. With the further development of laser technology, laser-assisted liposuction technology will shine in the field of plastic surgery.
