Beautiful Trap of Hyaluronic Acid

        　　Summer vacation is coming, besides the peak season of tourism, it is also a hot season for hosting classmates'associations. Faced with the old classmates, the most afraid is that they have a few more wrinkles, or face sagging, tears, pouches, plus cheek depression show old fashion, I really hope there is a simple, safe and no trace of the way to improve these defects. This issue of "Health Column" introduces the principle and related technology of "hyaluronic acid" filler, so that you can understand the risks associated with the pursuit of youth and beauty.

        Nowadays, plastic and cosmetic medicine is getting more and more advanced and accepted by people, especially injectable filler, because of its short recovery period, it is favored by the people. According to the American Association of Plastic and Aesthetic Surgery, there are about 14.44 million plastic and aesthetic treatments in the United States every year, of which only 192,000 are plastic surgery, while 952,000 are non-surgical plastic (such as injectable fillers). Because the hyaluronic acid market brand is numerous, and aquatic products, counterfeit products flooding, often make consumers confused, coupled with some beauty salon staff privately inject hyaluronic acid for customers, but also make the consumer market more chaotic.
         　　
         What is hyaluronic acid?
         Hyaluronic acid (HA) is a kind of mucopolysaccharide, which widely exists in animal tissues, also known as "glucuronic acid". It is called "hyaluronic acid" in mainland China. It originally exists in connective tissue and dermis of human skin. It maintains the elasticity of skin, and also maintains the whole organizational structure and intercellular structure. Transfer function.
        
         The earliest hyaluronic acid product was extracted from chicken crown, but because of the risk of allergic reaction and infectious disease infection caused by injection into human body, it has been changed to bacterial fermentation to produce in Petri dishes to avoid rejection. Most of them were injected with arthritis in the early stage, but in recent years they have been widely used in cosmetology. Some manufacturers will distinguish by macromolecule, medium molecule and small molecule, while others will distinguish by viscosity. However, no matter which brand or strain, the chemical structure of the product is the same. Small molecule is suitable for hitting under the skin which is thinner. Large molecule is thicker and has a longer duration (which can last for one and a half to two years). It is suitable for hitting deeper and difficult to detect.
        
         Is hyaluronic acid the same as pin cosmetology?
         Small needle cosmetology usually refers to silica gel injection, but silica gel can not be discharged through the human body, which is easy to produce irregular granuloma lumps, accumulate in the body, or move around, or even penetrate into the dermis, affecting local blood circulation and lymphatic obstruction, and may cause disfigurement or infection. Therefore, Taiwan has completely banned silica gel in 1976. Perform small needle cosmetology.
        
         After hyaluronic acid is injected into the human body, it will gradually metabolize, and the subcutaneous tissue of the human body originally has this component, which is not easy to reject, so it is safe to use it for tissue filling. If improper tissue filler is used, it will not only cause infection, agglomeration, tissue fibrosis, but also displacement, deformation and other sequelae, which can be described as endless aftermath.
        
         Beating process of hyaluronic acid
         Before hyaluronic acid injection, it is necessary to clean the face first and then apply local anesthetic ointment by medical staff to reduce pain. After hyaluronic acid, analgesics and antibiotics will be prescribed to the public. In addition, there may be congestion or bruising after injection, it is better to apply ice compress, and try to avoid going to dusty places, while reducing the use of hot water to wash face, soak in hot springs, wash three warmth, because "hot" will increase the rate of hyaluronic acid degradation.
        
         Risk of damage?
         Hyaluronic acid is considered as a good tissue filler because of its bio-stability, non-translocation and insoluble water, besides its moisturizing property. Although it can be absorbed and metabolized by the human body, if the injector is not familiar with the distribution of blood vessels in the human body, there is a risk of damage. For example, some men hope to make the penis look more magnificent by hyaluronic acid, but because of the rich blood vessels in the penis, it is easy to enter the blood vessels by mistake, resulting in blockage, resulting in the upper blood circulation is not. Excellent, leading to local skin tissue necrosis; For example, augmentation rhinoplasty, if you do not understand the structure of the nasal cavity or overexert, it may compress blood vessels, blood supply can not reach the nasal skin tissue, it may also cause local skin tissue necrosis.

        Safety first
         General sources of hyaluronic acid infection include: product manufacturing process, packaging, transportation, preservation, effective use date, sterile operation technology in beating process, etc. In addition to the need for consumers to select qualified hospitals, whether hospitals pay attention to "after-sales service" should also be considered. In addition, the choice of physicians is more important, not only with technology, but also with aesthetic literacy, it will not make a strange appearance, and a good doctor can achieve the maximum goal with the minimum injection volume. Therefore, it is suggested that the qualifications of physicians should be examined first, and experienced doctors can deal with problems in time. Not only that, consumers should also understand the origin of the product, see clearly the brand name on the package, preferably with the license of the Department of Health, at the same time, ask the medical staff for the package box and copy sheet instructions, and ask the doctor to open the product in person before beating, otherwise it is easy to mix the eyes with the eyes.
        
         Finally, I remind you that plastic and cosmetic injection is a medical practice, which has its risks. We must think twice before we act. Don't be led by advertisements and media marketing.
