With the wheel of social development and progress, more and more people notice the importance of anti-aging, and thus the pursuit of healthy, scientific anti-aging methods, has become a fashionable trend. However, based on some traditional anti-aging concepts and methods, people, in addition to maintaining a good body in the “physiological” normal state and “psychological” state of health, gives more attributes of health, that is, social interaction and aesthetic enhancement. Therefore, under the driving force of the above social demand, various disciplines have produced the branch disciplines with anti-aging as the center of gravity, and the sound and light technology to treat all kinds of diseases or problems caused by aging has become a sunrise discipline, and because of its excellent therapeutic effect, “non-invasive and painless” treatment characteristics, it is rapidly being favored by the majority of medical practitioners and patients. favored by the majority of medical workers and patients. As a sub-discipline of medical aesthetics, acousto-optic technology in the scope of medical aesthetics is more widely used, which not only involves a large number of aesthetic categories, but also has its own unique technical standards, the need for accurate acousto-optic technology support, therefore, many plastic surgery and dermatology doctors try to make a more accurate definition of the discipline, and standardize its treatment methods and research systems, but it is difficult to make a complete summary of it. It is difficult to summarize it in its entirety, because this technology is changing rapidly. Each medical practitioner has his or her own opinion on the subject. Some domestic authors summarize the beauty of skin science as: medical aesthetics as a guide, based on the theory of skin science, the use of medicine and aesthetics combined with the technical means, the study of human skin’s anatomical structure and physiological function and the implementation of the maintenance, improvement, restoration and shaping of the human skin and beauty and its regularity of the disciplines, which is a backbone of aesthetic medicine, clinical application of the disciplines. Then as a sound and light anti-aging discipline, skin beauty is only a part of it, but also includes the scope of plastic surgery treatment, should cover the facial fat, fascia, muscle, bone and other rejuvenation treatment, so that the tissue to restore the original physiological characteristics and anatomical position, so that the face of the applicant to look more youthful and more beautiful treatment method. Acousto-optic anti-aging treatment, which is based on a set of brand-new theories put forward by the great scientist Albert Einstein in 1916, has gradually replaced the traditional treatment methods with its features of short treatment time, quick effect, long time, and wide range of effects. At present, the effects of spot removal, skin rejuvenation, hair removal, treatment of capillary dilatation, anti-aging, tightening, etc. can not be completely replaced by other beauty methods. In recent years, due to the medical workers on the sound and light technology to a large extent of understanding and application of the basis of the sound and light products used for facial anti-aging is also more and more, and its product technology is also in the process of continuous improvement. Under the theoretical support of the in-depth study of sound and light technology and the mechanism of interaction between tissues, more and more technologies have been developed and used in combination with each other, so that we have a wider and wider range of treatments with better and better results.
