          The main principle of laser beauty products is to use the light wave band that is beneficial to the human body, has strong penetration ability and high absorption rate of human tissue, uses the stimulation effect of weak laser on biological tissue, and simultaneously irradiates multiple beauty acupoints on the face. Facial acupoints and local skin irradiation can effectively stimulate facial meridian points, accelerate blood circulation, improve skin supply status, increase skin tissue nutrition, promote skin metabolism, remove aging and atrophied epithelial cells, enhance facial skin collagen vitality, promote Cell regeneration ability and the secretion function of sebaceous glands and sweat glands, stimulate the peripheral nerves of the epidermis, promote the anabolism and tissue repair of the body, thereby improving the dull complexion, pigmentation, sagging skin, wrinkles, drooping eye bags, dark circles, large pores, rough skin, etc. , make the facial skin rosy and shiny, enhance elasticity, delay skin aging, and have the effect of beautifying and beautifying.



          1.Lasers are becoming more and more widely used in the beauty industry


          Laser is a monochromatic light with high energy, precise focusing and certain penetrating power, which acts on human tissue and generates high heat locally to achieve the purpose of removing or destroying the target tissue. Various pulsed lasers of different wavelengths can treat various Vascular skin diseases and pigmentation, such as nevus of Ota, port-wine stains, freckles, age spots, telangiectasia, etc.; as well as tattoo removal, eyeliner washing, eyebrow washing, scar treatment, etc.; high-energy ultra-pulse CO2 laser, erbium laser for wrinkle removal , skin resurfacing, treatment of snoring, teeth whitening, etc., have achieved good results, opening up more and more broad areas for laser surgery.



          2.Laser surgery has incomparable advantages over traditional surgery


          First of all, laser surgery does not require hospitalization, the surgical incision is small, there is no intraoperative bleeding, the trauma is light, and there is no scar. For example, the traditional surgical method for the treatment of eye bags has shortcomings such as wide exfoliation, heavy intraoperative bleeding, slow postoperative healing, and easy formation of scars. It does not require sutures, does not affect normal work, has less edema at the surgical site, has faster recovery, and has no scars, which makes it unmatched by traditional surgery. Some endoscopic surgeries that cannot be performed due to excessive bleeding can be replaced by laser cutting. (Note: there is a certain range of adaptation)


          3.The effect of laser in the treatment of vascular skin diseases


          Excellent use of pulsed dye laser in the treatment of port-wine stains, with remarkable curative effect, little damage to surrounding tissues, and almost no scarring. Its appearance has become a revolution in the history of port-wine stain treatment, because in the history of port-wine stain treatment, radiation, freezing, electrocautery, surgery and other methods have a high incidence of scarring, and often depigmentation or deposition. It results in a high degree of destruction of vascular tissue, which is highly accurate and safe, and will not affect the surrounding adjacent tissue. Therefore, laser treatment of telangiectasia is also effective.


          In addition, due to the advent of variable pulsed lasers, the removal of unsatisfactory tattoos and the treatment of various pigmented skin diseases such as Ota nevus and age spots have achieved major breakthroughs. This type of laser is based on the theory of selective photothermal effect (that is, lasers of different wavelengths can selectively act on skin lesions of different colors), using its powerful instantaneous power, highly concentrated radiation energy and pigment selectivity, and extremely short pulses. Wide, make the laser energy concentrate on the pigment particles, vaporize them directly, crush them, and excrete them through the lymphatic tissue without affecting the surrounding normal tissues, and it has exact curative effect, safe and reliable, no scar, small pain and deeply rooted in the hearts of the people.


          4.Laser surgery has created a new era of medical beauty


          High-energy ultra-pulsed CO2 laser skin resurfacing has opened up new technologies in cosmetic surgery.
