CO2 fractional laser

　　CO2 dot matrix laser = dot matrix + CO2 laser

　　The dot matrix is ​​not a laser, but refers to a working mode of the laser. As long as the diameter of the laser beam (spot) is less than 500μm, and the laser beam is regularly arranged in a dot matrix, the laser working mode at this time is a dot matrix laser .

　　CO2 laser is a kind of molecular laser, the main substance is carbon dioxide molecule. Like other gas lasers, the working principle of CO2 lasers and their stimulated emission process are also more complicated. You can understand it as a laser excited from CO2 gas under a special device.

　　CO2 lattice laser is the CO2 laser emitted in lattice pattern. For example, with a flashlight, normal opening is a large light spot. The dot matrix mode is to cover the front with a gauze. The pattern of the large light spot has not changed, but it is divided into small light spots (the real dot matrix is ​​not the cutting of the large light beam. , It is made into a lattice when launching). The millimeter-level and centimeter-level beams are made into micron-level micro-beams.

　　Principle of action

　　Its principle of action is mainly “focal photopyrolysis and stimulating effect”.

　　The carbon dioxide laser treatment instrument emits super-pulse laser with a wavelength of 10600nm, and finally outputs it in a lattice manner. After acting on the skin, a number of small thermally damaged areas with three-dimensional cylindrical structures are formed. There are undamaged normal tissues around each small damaged area, and the keratinocytes can crawl quickly to make it heal quickly. It can rearrange the proliferation of collagen fibers and elastic fibers, restore the content of type I and type III collagen fibers to the normal ratio, change the pathological tissue structure, and gradually return to the normal state.

　　The main target tissue of CO2 fractional laser is water, and water is the main component of the skin, which can cause dermal collagen fibers to be heated to shrink and degenerate, and induce wound healing in the dermis, the collagen produced is deposited in an orderly manner, and promotes collagen proliferation , Thereby improving skin elasticity and reducing scars.

　　CO2 fractional laser can instantly heat the water in the tissue, vaporize the epidermis and the dermis (scars) of different depths when it acts on the skin, creating vaporization pits on the skin. Because of its high peak energy, small heat-induced secondary damage zone, precise vaporization of tissue, and light damage to surrounding tissues, laser wounds can heal within 4 to 7 days, and the possibility of causing complications such as hyperpigmentation or hypopigmentation is small. At the same time, there are many pigments in the epidermis of our skin, which will fade with the peeling and peeling of the epidermis. This is also the principle of skin whitening after fractional laser treatment.

　　Treatment range

　　CO2 fractional laser treatment of scars is a breakthrough in scar treatment, and its curative effect is better than topical anti-scarring drugs in non-surgical treatment. The main mechanisms include: ① damage and inhibit the vascular tissue in the scar tissue; ② remove the scar tissue by vaporization; ③ inhibit the formation and excessive proliferation of fibroblasts; ④ induce the apoptosis of fibroblasts.

　　Skin rejuvenation enhancement, if you do a deep skin rejuvenation, the CO2 laser will have a skin rejuvenation effect, and the effect will last for one year.

　　1. Anti-aging: skin lifting, wrinkle removal, skin peeling; photo-aging skin improvement.

　　2. Acne: acne vulgaris, enlarged pores, seborrheic dermatitis, etc.

　　3. Scars: treatment of depressed and hyperplastic scars.

　　4. Problem skin: repair of sensitive skin; treatment of hormone-dependent dermatitis.

　　5. Auxiliary enhancement product introduction: Import some specific skin function products to increase the efficacy.

　　6. Treatment of various proliferative skin diseases: age spots, warts, tumors, etc.

　　7. Hair hyperplasia: assist in the treatment of male alopecia.

　　8. Female vagina tightens.
