Laser is used more and more widely in the beauty industry.
(1) Laser can remove or destroy target tissues by generating high energy, precise focusing, and certain penetrating monochromatic light, which acts on human tissues and generates high heat locally. Various pulsed lasers with different wavelengths can treat various vascular skin diseases and pigmentation, such as nevus of Ota, nevus flammeus, freckles, age spots Telangiectasia, tattoo removal, eyeliner washing, eyebrow washing, scar treatment, etc; In recent years, some new laser instruments, such as high-energy ultra pulse CO2 laser and erbium laser, have achieved good results in wrinkle removal, skin abrasion, snoring treatment, tooth whitening, etc., opening up more and more broad fields for laser surgery.
(2) Laser surgery has incomparable advantages over traditional surgery. First of all, the laser surgery does not require hospitalization, the surgical incision is small, there is no bleeding during the operation, the wound is light, and there is no scar. For example, the traditional surgical method for the treatment of eye bags has many shortcomings, such as wide range of peeling, more bleeding during the operation, slow healing after the operation, and easy to form scars. However, the application of high-energy ultra pulse CO2 laser to treat eye bags has the advantages of no bleeding during the operation, no suture, no impact on normal work, light edema at the hand operation site, fast recovery, and no scars, which makes the traditional surgery incomparable. Some endoscopic operations that cannot be performed due to excessive bleeding can be completed by laser cutting instead. (Note: there is a certain scope of application)
(3) Laser has achieved remarkable results in the treatment of vascular skin diseases and pigmentation. Using pulsed dye laser to treat nevus flammeus has obvious curative effect, little damage to surrounding tissues, and almost no scar. Its appearance has become a revolution in the history of nevus flammeus treatment, because in the history of nevus flammeus treatment, radiation, freezing, electrocautery, surgery and other methods have high scar incidence, and often have depigmentation or deposition. Laser treatment of vascular dermatosis is to use oxyhemoglobin to selectively absorb laser of a certain wavelength, which leads to high destruction of vascular tissue. It has high accuracy and safety, and will not affect surrounding adjacent tissues. Therefore, laser treatment of telangiectasia is also effective.
In addition, thanks to the advent of variable pulse lasers, the removal of unsatisfied tattoos and the treatment of various pigmented skin diseases such as nevus of Ota and senile plaques have made a major breakthrough. According to the theory of selective photothermal effect (that is, lasers of different wavelengths can selectively act on skin lesions of different colors), such lasers use their powerful instantaneous power, highly concentrated radiant energy, pigment selectivity, and extremely short pulse width to concentrate laser energy on pigment particles, vaporize and smash them directly, and expel them from the body through lymph tissue, It does not affect the surrounding normal tissues, and it is safe, reliable, scar free, painless and deeply rooted in the hearts of people with its definite curative effect.
(4) Laser surgery has ushered in a new era of medical cosmetology. High energy ultra pulse CO2 laser dermabrasion and skin replacement has developed a new technology of cosmetic surgery. It uses high-energy, extremely short pulse laser to instantly vaporize aging and damaged skin tissue without damaging surrounding tissue, and almost no bleeding during treatment, and can accurately control the depth of action. Its effect has been fully recognized by the international medical plastic and aesthetic circles, and is known as "creating a new era of medical beauty"; In addition, there are high-energy ultra pulse CO2 laser devices for the treatment of bags under the eyes, snoring, and even laser whitening of teeth. With its safe and accurate efficacy, simple and fast treatment has created miracles in the medical beauty industry. Laser cosmetology makes medical cosmetology take a big step forward, and endows medical cosmetology with renewed connotation. For example, laser can remove facial nevus.
