Laser cosmetic surgery?

For those who love beauty, no matter who they are or at what age, they all hope to be young and beautiful. However, with the increase of age, the moisture in the skin's elasticity will slowly be lost, and modern women are under great work and life pressures. Working overtime and staying up late are commonplace. If you do not pay attention to maintenance in daily life, it is easy to cause wrinkles and spots on your facial skin, which will seriously affect your personal image.

Laser beauty is to pass a laser beam of a specific wavelength through the epidermis and dermis to destroy pigment cells and pigment particles. The fragments are processed and absorbed by the body's macrophages. It is safe and does not leave scars, and it effectively achieves the purpose of whitening.

The main principle of laser beauty products is to use light wave bands that are beneficial to the human body, have strong penetration ability, and high absorption rate of human tissue, and use weak laser to stimulate biological tissues. At the same time, multiple beauty points on the face are irradiated. By irradiating facial points and local skin, it effectively stimulates facial meridian points, accelerates blood circulation, improves the supply status of the skin, increases the nutrition of skin tissue, promotes skin metabolism, removes aging and atrophy of epithelial cells, enhances the vitality of facial skin collagen, promotes cell regeneration ability and the secretion function of sebaceous glands and sweat glands, stimulates the peripheral nerves of the epidermis, and promotes the body's anabolism and tissue repair, thereby improving facial dull skin color, pigmentation, loose skin, wrinkles, sagging eye bags, dark circles, large pores, rough skin, etc., making the facial skin rosy and shiny, with enhanced elasticity, delaying skin aging, and achieving the effect of beauty care.

1. Lasers are increasingly used in the beauty industry

Laser produces high-energy, precisely focused, and penetrating monochromatic light, which acts on human tissue to generate high heat locally, thereby achieving the purpose of removing or destroying target tissue. Pulsed lasers of various wavelengths can treat various vascular skin diseases and pigmentation, such as Ota's nevus, port wine stains, freckles, age spots, capillary dilation, etc.; as well as tattoo removal, eyeliner removal, eyebrow removal, scar treatment, etc.; high-energy ultra-pulsed CO2 lasers and erbium lasers are used for wrinkle removal, skin resurfacing, snoring treatment, teeth whitening, etc., and have achieved good therapeutic effects, opening up an increasingly broad field for laser surgery.

2. Laser surgery has advantages that traditional surgery cannot match

First of all, laser surgery does not require hospitalization, the surgical incision is small, there is no bleeding during the operation, the trauma is mild, and there is no scar. For example, traditional surgical methods for treating eye bags have disadvantages such as a wide range of dissection, excessive bleeding during surgery, slow postoperative healing, and easy scar formation. The use of high-energy ultra-pulsed CO2 laser to treat eye bags has advantages such as no bleeding during surgery, no need for sutures, no impact on normal work, mild edema at the surgical site, quick recovery, and no scars, which are incomparable to traditional surgery. Some endoscopic surgeries that cannot be performed due to excessive bleeding can be replaced by laser cutting. (Note: There is a certain scope of application)

3. Effectiveness of laser in the treatment of vascular skin diseases

Excellence uses pulsed dye laser to treat port-wine stains, with significant results, minimal damage to surrounding tissues, and almost no scars. 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 all have a high incidence of scars and often cause pigment loss or deposition. This results in a high degree of destruction of vascular tissue with high accuracy and safety, and will not affect the surrounding adjacent tissues. Therefore, laser treatment of telangiectasia is also effective.

In addition, with the advent of variable pulse lasers and other technologies, major breakthroughs have been made in the removal of unsatisfactory tattoos and the treatment of various pigmented skin diseases such as nevus of Ota and age spots. 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). It uses its powerful instantaneous power, highly concentrated radiation energy, pigment selectivity, and extremely short pulse width to concentrate the laser energy on pigment particles, directly vaporize and break them up, and excrete them out of the body through the lymphatic tissue without affecting the surrounding normal tissues. It is deeply rooted in people's hearts for its precise efficacy, safety, reliability, no scars, and little pain.

High-energy ultra-pulsed CO2 laser resurfacing has pioneered new technologies in cosmetic surgery.

It changes the focusing characteristics of the laser to turn the laser point into a light spot. It uses a pattern generator to drive the scanning galvanometer to make the light spot scan according to a certain pattern and generate high heat instantly, thereby producing effects on the skin from shallow to deep, namely vaporization, irreversible thermal damage, and heating area. These effects can be used to remove target tissue within the scanning range. There are two types of graphic scanning methods: sequential scanning and random scanning (which causes different thermal damage to local areas of the skin). The intensity, density, shape and size of each light spot are controlled by a computer, thereby accurately controlling the depth of removal of the target tissue to achieve the purpose of treatment. The effects of laser skin resurfacing include: epidermal vaporization (can remove freckles, seborrheic keratosis, and photokeratosis) and stimulation of new collagen synthesis (removing wrinkles).
