What is endoscopic wrinkle reduction? It is a minimally invasive wrinkle reduction technique. With the assistance of endoscope, it removes wrinkles and corrects sagging of forehead wrinkles, wrinkles between eyebrows and outer corners of eyes through small incisions within the hairline, restores facial skin firmness and good shape of eyelids, and removes aging signature wrinkles for a long time under the premise of maintaining normal facial expression to achieve a youthful and scarless effect. What are the types of facial wrinkles and the reasons for their formation? The movement of facial expression muscles produces corresponding wrinkles while expressing various expressions, such as head lines, frown lines, and wrinkles below the outer corners of the eyes. At the earliest, wrinkles appear only when making facial expressions, and do not appear in a calm state, which is called dynamic wrinkles; with further aging and changes in the elastic fibers of the skin, constant wrinkles appear on the face, which is called static wrinkles, and are more obvious when making facial expressions. What are the principles of facial aging? The most accepted theory of facial aging is the result of the gradual sinking of soft tissues due to the cumulative effect of gravity. The most important factors also include loss of collagen and elastin in the skin due to progressive photodamage and solar elastic tissue degeneration, which is evident in women’s skin at around 35 years of age; changes in the levels of estrogen and male hormones leading to thinning of the skin, atrophy of the subcutaneous fat layer and proliferation of the deeper fat layers; loss of youthful tightness by sagging and displacement of adipose tissue; and shrinkage of the facial glands and resorption of the facial bone matrix. This leads to the aging face. What is the principle of endoscopic wrinkle reduction? Endoscopy is an auxiliary technical means by which the doctor can accomplish what used to be done with large incisions with only small incisions. Due to its magnifying effect, it makes the operation more accurate, and it can precisely deal with the expression muscle that produces the corresponding wrinkles without damaging other structures, thus achieving highly selective removal of wrinkles and at the same time lifting up the sagging facial structures to achieve rejuvenation. Because of the small damage, the recovery is fast, and you can completely return to work in 5-7 days after the operation. What is the current status of endoscopic wrinkle removal? The endoscopic technique of brow lifting was first reported by Vasconez and Isse in 1992, and publicly published by Chaj- chir in 1993, and gradually emerged with the booming development of lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo-lumbo. Our research and practice of endoscopic wrinkle reduction technology in combination with the characteristics of the continental race also has a history of 10 years, from the initial few patients to a dozen patients per year, to the current monthly more than a dozen to more than 20 cases of patients with good results. The theory and operation system of facial rejuvenation surgery design and endoscopic minimally invasive surgery series have been formed, and the technical level is at the forefront of China. The results have been published and exchanged in international and domestic academic conferences and journals. Who are the adaptable people of endoscopic wrinkle removal? It is suitable for people of all ages. ① For young people who only have dynamic wrinkles, the main content is to remove the annoying dynamic wrinkles on the face, for example, many young girls have annoying wrinkles on the outer corner of the eyes and the lower outer corner of the eyes when they smile, and the endoscopic technology can permanently remove the annoying wrinkles and avoid the static wrinkles that may appear in the future when they age; ② For people aged 35-45 years old, the removal of wrinkles, at the same time, is usually done with the help of endoscopic technology, which can be used to remove wrinkles. ②For people around 35-45 years old, removing wrinkles is usually combined with further lifting of eyebrows and eyes to achieve good rejuvenation results, and lifting of cheeks if accompanied by sagging. (iii) For those who are older and have looser skin, it can be combined with midface dermabrasion to tighten the skin. Is the small endoscopic incision less effective for wrinkle reduction than the traditional large incision facelift? Domestic and foreign data have confirmed that although endoscopic wrinkle removal has a small incision and does not remove the frontotemporal skin, the wrinkle removal effect is exact, and there is no significant difference in the lifting and maintenance effect compared with traditional incision wrinkle removal. What are the limitations of endoscopic wrinkle reduction? Endoscopic wrinkle removal is only a technology, which has absolute advantage for patients who do not need to remove skin, and if it is for candidates with very loose face and neck, it needs to be combined with face and neck peeling surgery to achieve better results. Will there be dull facial expression after endoscopic wrinkle reduction? Since endoscopic wrinkle removal only removes unwanted wrinkles, its high selectivity will not have any effect on other facial expressions, and it is a technique worth promoting because of its fast recovery, short swelling time, no hair loss and no obvious postoperative incision marks. Of course, it requires a perfect combination of solid anatomical foundation, rich clinical experience and sophisticated endoscopic equipment to achieve. What is the difference between endoscopic wrinkle reduction and Botox injection? During endoscopic wrinkle removal surgery, the method adopted for the expression muscle that produces unpleasant wrinkles is highly selective removal, which is permanent and does not involve the surrounding muscles, and the sagging tissues are uplifted through the operation; whereas the principle of Botox injection for wrinkle removal is to paralyze the expression muscle that produces unpleasant wrinkles (3-6 months), which is often due to the diffusion of the drug in the process of injection and the surrounding area, and the effect will be amplified and unpleasant expressions will appear. The effect is amplified by the unnatural and asymmetrical expression, and the effect of Botox will cause further sagging of the corresponding part of the facial tissues.
