1, laser is more and more widely used in beauty industry.
Laser produces monochromatic light with high energy, accurate focus and certain penetrating power, which acts on human tissues to produce high fever, thus cutting or destroying target tissues. Pulsed laser with different wavelengths can treat various vascular dermatoses and pigmentation, such as nevus OTA, nevus flammeus, freckles, senile plaques and telangiectasia. And tattoo removal, eyeliner washing, eyebrow washing, scar treatment, etc. High-energy ultra-pulse CO2 laser and erbium laser can remove wrinkles, grind and change skin, treat snoring and whiten teeth. , and achieved good results, opening up more and more broad fields for laser surgery.
2. Laser surgery has incomparable advantages over traditional surgery.
First of all, laser surgery does not require hospitalization, with small incision, no bleeding during operation, light trauma and no scars. For example, the traditional surgical treatment of bags under the eyes has many shortcomings, such as wide peeling range, more bleeding during operation, slow healing after operation and easy scarring. The application of high-energy ultra-pulse CO2 laser in the treatment of eye bags has the advantages of no bleeding, no suture, no influence on normal work, light edema at the surgical site, quick recovery and no scar left, which is incomparable to traditional surgery. Some endoscopic operations that cannot be performed due to excessive bleeding can be completed by laser cutting instead. (Note: There is a certain range of adaptation)
3. The role of laser in the treatment of vascular dermatosis.
Pulsed dye laser treatment of port wine nevus has obvious curative effect, little damage to surrounding tissues and almost no scar. Its appearance has become a revolution in the history of treatment of port wine stains, because in the history of treatment of port wine stains, radiation, freezing, electrocautery, surgery and other methods have a high incidence of scars, and pigment loss or deposition often occurs. Resulting in high degree of vascular tissue destruction, high accuracy and safety, and not affecting the surrounding adjacent tissues. Therefore, laser treatment of telangiectasia is also effective.
In addition, due to the appearance of variable pulse laser, great breakthroughs have been made in removing unsatisfactory tattoos and treating various pigmented skin diseases such as OTA nevus and senile plaques. According to the theory of selective photothermal effect (that is, lasers with different wavelengths can selectively act on skin lesions 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 laser energy on pigment particles, directly vaporize and crush them, and excrete them through lymphatic tissues, without affecting the surrounding normal tissues. It is deeply rooted in people's hearts because of its exact curative effect, safety and reliability, no scar and little pain.
4. Laser surgery initiated a new era of medical beauty.
High-energy ultra-pulse CO2 laser peeling and skin changing has opened up a new technology in cosmetic surgery.
Scanning pattern
Scanning pattern
By changing the focusing characteristics of the laser, the laser spot becomes a light spot, and the scanning galvanometer is driven by the pattern generator to scan the light spot according to a certain pattern, which instantly produces high heat, and the effects of making the skin from shallow to deep are gasification, irreversible thermal damage and heating area. These effects can be used to remove the target tissue within the scanning range. There are two scanning methods for graphics: sequential scanning and random scanning (different thermal damage to local skin areas). The intensity and density of each spot and the shape and size of the scanned image are controlled by the computer, so as to accurately control the depth of the target tissue and achieve the purpose of treatment. The functions of laser skin changing include: epidermal gasification (which can remove freckles, seborrheic keratosis and actinic keratosis) and stimulating the synthesis of new collagen (removing wrinkles).
Laser skin replacement not only overcomes the shortcomings of traditional methods, such as easy bleeding and difficult depth control, but also stimulates the elastic fibers of the skin and makes them shrink. The contraction of elastic fibers can tighten the skin, further promote the disappearance of superficial wrinkles, and the wrinkle removal effect is more obvious. The wrinkle removal effect is also related to the size of the spots used. 1.3mm spot has fast processing speed and uniform coverage. 0. 12mm spot penetrates deeply, so the recovery time is short. Avoid light before and after laser skin changing, take vitamins properly, and apply medicine to face or change medicine after operation to prevent infection. Pigmentation of skin, which occasionally occurs in skin replacement surgery, is more common in yellow people. The incidence of transient pigmentation is high within three months after operation, and this pigmentation disappears within half a year without recurrence. This situation does not need special treatment, so you should avoid light and use some sunscreen skin care products under the guidance of a doctor. In order to avoid permanent pigmentation, we should pay attention to the selection of surgical indications, try to choose patients with lighter or darker skin color, and use skin replacement with caution for those with skin color between the two.
In addition, its safe and accurate curative effect and simple and quick treatment method have created one miracle after another in the field of medical beauty. Laser cosmetology has made medical cosmetology take a big step forward and given the connotation of medical cosmetology renewal.

Using pulsed dye laser to treat port wine nevus is effective, with little damage to surrounding tissues and almost no scar left. Its appearance has become a revolution in the treatment history of port wine nevus, because in the treatment history of port wine nevus, radiotherapy, freezing, electrocautery, surgery and other methods have a high incidence of scar, and pigment loss or pigmentation often occurs, resulting in high vascular tissue damage. It is highly accurate and safe, and will not affect the surrounding adjacent organizations. Therefore, laser treatment of telangiectasia is also effective. In addition, due to the appearance of variable pulse laser, great breakthroughs have been made in removing undesirable tattoos and treating various pigmented skin diseases such as Ota nevus and senile plaque. According to the theory of selective photothermal effect, this kind of laser can selectively act on skin lesions of different colors.
