The five stages of the development of laser freckle removal beauty

2021-12-27 15:56:06

     In today's society, with the development of science and technology, lasers have gradually entered people's lives and have had a great impact on people's lives. Among them, has become an advanced and effective freckle removal technology, the development of this technology, to the majority of people, especially some beauty lovers have brought great gospel, laser freckle removal, with its no damage, no scarring, exact curative effect, less pain and safe and simple treatment characteristics, more and more favored by the majority of beauty lovers.

      Lasers produce a high-intensity instantaneous energy of visible light, and lasers of different wavelengths are absorbed by special colors or pigments in the skin, such as freckles that easily absorb green light. The functions of lasers with various wavelengths of energy are also different, and there are currently 7 or 8 kinds of lasers used to treat skin problems. As often heard of ruby (RUBY) laser is the use of laser principle, with ruby as the medium, mainly for black and coffee color pigments, pigment spots, the combination of light and pigment, so that it is decomposed, when the pigment is gradually absorbed by the body, the color of the spots will fade

      

      1, the basic research stage of laser medical application - began to study the interaction between laser and biological tissue In 1960, Maiman (Maiman TH) made the world's one laser - ruby laser, and since then Goldman L (a famous dermatologist), known as the "founder of laser medicine", has begun to study the interaction between laser and biological tissue on the skin; In 1963, Goldman L began to apply ruby lasers to benign skin lesions and tattoo treatments with success, pioneering laser medical applications.

     

     2. Clinical trial stage - safety has not been solved, and good cosmetic effects have not yet been achieved

In 1970, Goldman L et al. first used continuous CO2 lasers to treat basal cell carcinoma and cutaneous hemangiomas, which set off the first laser medical boom at home and abroad. In the 1970s, continuous lasers used in skin beauty also included Lasers such as Ar+, Cu Vapor and Nd:YAG. However, due to the non-selective thermal damage of these continuous lasers to tissues, it is often accompanied by side effects such as hypopigmentation of skin scars after treatment, and good cosmetic results have not been achieved.

     

      3, the formation of selective photothermal action theory - the initial realization of the perfect unity of laser effectiveness and safety In 1983, Anderson RR and Parrish JA proposed selective photothermal action theory - that is, "photothermal separation" theory, that is, according to the biological characteristics of different tissues, select the appropriate wavelength, energy, pulse duration, in order to ensure the effective treatment of diseased tissues at the same time, try to avoid damage to the surrounding normal tissues.


This theory realizes the perfect unity of the effectiveness and safety of lasers, and is a milestone in the history of the development of laser medicine, especially laser aesthetic medicine. According to the selective photothermal effect, the new laser technology has been used in research, diagnosis and treatment of diseases and aesthetic treatment relatively maturely, and has formed a large professional team, which is one of the important symbols of the formation of laser medicine disciplines.

      

     4. The development and maturity of laser beauty


Since the 1990s, with the progress of science and the development of laser technology, new beauty laser machines have sprung up like mushrooms, and have made very significant achievements, such as Q-switch lasers, variable pulse width multiplier lasers, pulsed ruby lasers, emerald lasers, Nd:YAG lasers and semiconductor lasers, high-energy super-pulse CO2 lasers and erbium lasers, etc., which have also achieved certain clinical efficacy, but have not yet reached the height of precision treatment and skin beautification.

      

      5. The epoch-making turn of laser beauty - spectral U skin technology The highest point of safe and precise treatment and comprehensive skin beautification effect


Different laser wavelengths act on the skin tissue, forming different absorption values to form an absorption curve, which is called a "spectral map". The core of spectral U skin technology is to use the principle of laser selective absorption, by accurately displaying the absorption coefficient of skin lesions on a specific wavelength laser, using different lesion tissues, different skin types of selective absorption principle of different wavelength lasers, only for the target tissue skin, and no harm to other normal tissues, to achieve good treatment, skin beautification effect.
