In recent years, a trend of “apple muscle” injection has quietly emerged in the cosmetic industry. The top of the film and television stars down to the civilian beauty quickly follow the wind and into the dance with the wind. What is “apple muscle”? Why is it so popular? Is this procedure suitable, safe and feasible? The so-called apple muscle is an area located in the cheek area under the lid. It consists of the bony zygomatic prominence, part of the zygomatic fat pad and subcutaneous fat. In order to increase the volume of soft tissues and achieve a fuller effect, a filler (hyaluronic acid is currently popular) is injected into the subcutaneous fat layer of the area. This method first started in Europe and America, then spread to Japan, Korea and Taiwan, and finally entered the mainland. Because of the facial characteristics of the European and American races, the bony contours are clear, with high brow bones, high nasal bridge, and high cheekbones with deep-set eye sockets. Many people will choose to apply injections to fill in these areas (note that it is not just the cheekbones) because of the lack of bony contours thus, it can be said to be a good indication for this procedure, which can indeed beautify this European beauty. To adapt to the European and American aesthetics, many Asian populations living there soon followed suit and eventually brought this procedure to us. At a later time many people imposed the Eastern Zhou Yi, Bagua and Facial Sciences on it, saying that this is “the image of a prosperous husband”, and beautiful young women were even more attracted to it and had a good reason: “Honey, this is all for your own good!” The sugar-coated shells quickly knocked each other down and gave generously. So the popularity of surgery is even more logical! But, I’m sorry, I can’t help but twist, as mentioned before, this should be the “patent” project of the European and American races, his indications are limited. Asian people are beautiful with curves and softness, and such beauty is accepted and recognized in Asian people, and is limited by the cranial soft tissue of our species! If you go against this physiological aesthetics, it is bound to be counterproductive and suspicious of following the same example. Don’t forget, the so-called “husband’s face” is to “compel” everyone with the photo of the first lady of the United States! Of course, not all Asian races are unsuitable for this surgery, and it cannot be denied in its entirety. Personally, I think his indications include: 1, cranial structure close to the Western beauty eyebrows, brow bone, nasal bone is high and cheekbones slightly lacking. 2, due to professional needs, such as plane models, hosts, film and television actors, these jobs generally need a slightly “exaggerated” sense of beauty. 3, aging, facial soft tissue loss, bone degeneration. In fact, most of the European and American seekers belong to this category. 4, pathological, such as facial atrophy, traumatic depression, etc.. This type does not belong to the category of medical aesthetics. As for the safety of the surgery, generally speaking, because the injection level is not deep, it is very safe to choose a regular medical unit, a regular trained doctor to operate, and qualified and regular filler products, such as Ruilan, Yimei, etc. The main complications of the surgery are too shallow injection, too much or too little amount, infection in the operation area, and granulomatous growth. Injections should avoid menstrual period and avoid using blood-activating drugs such as aspirin and salvia within 5-10d. Finally, a reminder: there are indications for any surgery, so don’t go with the wind! Pre-operative study and doctor’s consultation and communication are very important!
