The beauty laser field mirror has the following four characteristics:
1. Laser is more and more widely used in beauty industry
Laser is a monochromatic light with high energy, accurate focusing and certain penetrating power, which acts on human tissues and generates high heat locally, so as to achieve the purpose of removing or destroying target tissues. Pulse lasers with different wavelengths can treat various vascular skin diseases and pigmentation, such as nevus OTA, nevus erythematosus, freckles, senile plaques, telangiectasia, etc; And tattoo, eye liner, eyebrow washing, scar treatment, etc. High energy ultra pulse CO2 laser and erbium laser have achieved good results in wrinkle removal, skin grinding and skin change, snoring treatment, tooth whitening and so on, opening up a wider and wider field for laser surgery.
2. Laser surgery has incomparable advantages over traditional surgery
First of all, laser surgery does not require hospitalization, with small surgical incision, no bleeding during operation, light trauma and no scar. For example, the traditional surgical method for the treatment of pouch has some disadvantages, such as wide stripping range, more intraoperative bleeding, slow postoperative healing and easy to form scar. The application of high-energy ultra pulse CO2 laser in the treatment of pouch makes the traditional operation incomparable because of its advantages, such as no bleeding, no suture, no impact on normal work, light edema, rapid recovery and no scar. Some endoscopic operations that cannot be performed due to excessive bleeding can be replaced by laser cutting. (Note: there is a certain scope of adaptation)
3. Effect of laser in the treatment of vascular skin diseases
The use of pulsed dye laser in the treatment of port wine stain has remarkable curative effect, little damage to the surrounding tissue and almost no scar. Its emergence has become a revolution in the history of nevus flammeus treatment, because in the history of nevus flammeus treatment, the incidence of scar is high by radiation, freezing, electrocautery, surgery and other methods, and depigmentation or calm often occur. It leads to the high destruction of vascular tissue, which has high accuracy and safety, and will not affect the surrounding adjacent tissues. Therefore, laser treatment of telangiectasia is also effective.
In addition, the advent of variable pulse laser has made a major breakthrough in the removal of unsatisfactory tattoos and the treatment of various pigmented skin diseases such as nevus of Ota and senile plaques. According to the theory of selective photothermal effect (that is, lasers of different wavelengths can selectively act on skin damage of different colors), this kind of laser uses its powerful instantaneous power, highly concentrated radiation energy, pigment selectivity and extremely short pulse width to concentrate the laser energy for pigment particles, vaporize and break them directly, and discharge them out of the body through lymphoid tissue, It does not affect the surrounding normal tissues, and is deeply rooted in the hearts of the people because of its accurate curative effect, safety and reliability, no scar, little pain.
4. Laser surgery has ushered in a new era of medical cosmetology
High energy ultra pulse CO2 laser skin grinding and skin replacement has opened up a new technology of cosmetic surgery.
By changing the focusing characteristics of the laser, the laser point becomes a spot. Using the pattern generator, the scanning galvanometer is driven to scan the spot according to a certain pattern, and high heat is generated in an instant, resulting in the effects from shallow to deep on the skin, including gasification, irreversible thermal damage and heating area. These effects can be used to remove the target tissue within the scanning range. The scanning methods of graphics are divided into sequential scanning and random scanning (different thermal damage to local areas of the skin). The intensity, density, shape and size of each spot are controlled by the computer, so as to accurately control the depth of removing the target tissue and achieve the purpose of treatment. The functions of laser skin replacement include skin gasification (removing freckles, seborrheic keratosis and photokeratosis) and stimulating the synthesis of new collagen (removing wrinkles).
