Nowadays, cosmetic surgery has become another consumption boom after buying houses, cars and travel. Beauty is divided into life beauty and medical beauty, double eyelids, nose job, liposuction and even eyebrow tattoo are medical beauty. For medical beauty state is a strict regulation, must obtain the corresponding beauty doctor qualification, and the main doctor must be engaged in the relevant professional for more than 5 years to apply. At present, many cosmetologists who claim to be able to do medical beauty do not have the qualifications to practice medical beauty, and many beauty advertisements claiming that the beauty surgery is “scarless, scarless and fast and safe” are also unscientific. The most important thing is that you can’t do it from the scientific principle of plastic surgery. Any surgery has trauma, as long as the knife, even the smallest surgery: double eyelid, nose, jaw pad, etc. These surgeries have scars, but the smart plastic surgeons try to make the scars not obvious, and hide them in some hidden places. For example, the double eyelid is inside the eyelid line, the nose is inside the nose, the jaw is inside the mouth, and the wrinkle lift is inside the hair, but he still has trauma, and surgery without trauma is impossible. Many consumers lack understanding of plastic surgery, they mostly decide where to go for cosmetic surgery through advertisements, and some overstatement of advertising has made many people believe that plastic surgery is without any risk. Zhu Li, deputy chief physician of the Department of Plastic Surgery at Peking University Third Clinical Medical College, who has extensive clinical experience, points out that this is not actually the case. Because we also do a lot of plastic surgery in this area, including those who make problems elsewhere to come to us for revision. There are a lot of asymmetrical positions after breast augmentation, which are very minor, and in serious cases there are infections. After liposuction, the skin is uneven or even skin necrosis. Some of these can be compensated for and some of them cannot, causing scars and deformities. In addition, many plastic surgery procedures now require the implantation of some materials in the human body, and generally doctors will recommend the use of imported materials and claim that it is a new technology. In the face of these new materials with English names, most consumers are confused and do not know how to choose. If a medical material is implanted in the human body, the simplest criteria for judging it are two, the first criterion it must be used for a long time. For example, a material used for 20 years, because after a long time, there is enough time to observe that this material has no side effects, this material can be worth considering. If a material has been used for 20 years and there are millions of cases, it is only when it has no toxic side effects through the observation of such a large population that it can be taken as the material of choice. There are risks in cosmetic surgery, that’s for sure. There is nothing wrong with loving beauty and pursuing it. But now many people still have a certain blindness in the understanding of cosmetic surgery. Fifty percent of teenage girls just read the propaganda to have cosmetic surgery, and do not have a good psychological tolerance. The cosmetic surgery does not only change a person’s physical appearance, but also has a great impact on the psychological aspect. So whoever is doing plastic surgery should consider it carefully before doing it. In addition, we should also remember the saying that in this world, each of us is unique.
