With the development of medical science and technology and the trend of the world, cosmetic treatment is becoming more and more common, and people's acceptance of fixed-knife treatment is getting higher and higher, especially facial filling injection, which is growing steadily at home and abroad. Dr. Zeng, chairman of the Cosmetic Medical Association of the Republic of China, said that with the increase of skin filler injection cases, the medical community has paid more and more attention to the safety and injection technology of cosmetic medical injections. Many foreign research reports and seminars have put forward treatment guidelines to follow, the most important of which is to use blunt needle instead of traditional sharp needle, which can avoid more than 99% of the complications of injecting fillers into blood vessels by mistake, leading to skin necrosis or even blindness caused by vascular embolism. Chairman Zeng said that at present, the most common injection courses of cosmetic medicine in China are hyaluronic acid, microcrystalline porcelain, autologous fat injection and collagen, but many doctors prefer to use traditional sharp needles to apply fillers, which has the advantages of easy injection and less pain for patients, but it is also easy to cause abrasions, increasing the risk of being applied to dangerous parts, especially eyebrows, nose, decree lines and other parts, and sometimes unfortunately entering blood vessels. The Medical Beauty Association suggested that doctors should use blunt needles to ensure safety when injecting fillers in these three parts. At present, the medical association has formulated a safety guide for filler injection, which will be issued to member doctors in the near future. The Medical Association of Aesthetic Medicine attaches great importance to the education and training of its member doctors. Dr. Song Fengyi, director of education of the Aesthetic Medical Association of the Republic of China, said that the Aesthetic Medical Association attaches great importance to the education and training of cosmetic medical practitioners. Education and training courses on injection and phototherapy in cosmetic medicine are held every year. Since 2006, micro plastic injection education and training courses have been offered, each time lasting 32 hours, and 8 10 doctors have been trained. Since 2005, photoelectric therapy courses have been offered for 40 hours each time, and 679 doctors have been trained. The medical association requires that members who have no relevant practical experience must attend training courses in order to engage in this treatment. Communicate fully before receiving treatment and don't listen to exaggerated medical advertisements. Chairman Zeng reminded that any medical behavior has certain risks. People should not listen to exaggerated medical advertisements before receiving cosmetic treatment, but should fully communicate with doctors before receiving treatment, understand the success rate of treatment, assess the risk of related complications, and avoid medical disputes caused by excessive expectations.
