The photothermal effect is the main mode of action of current clinical laser applications. When heat energy acts on the surface of a tissue, it will directly heat the tissue within an absorption length. The heat is also conducted to the surrounding tissue through thermal relaxation and is not conducted to adjacent tissues. The heat vaporizes or removes tissue near the surface. The rate of tissue removal depends on the concentration of laser energy in the tissue. The higher the laser power, the faster the water vaporizes and the tissue is removed, and the minimal heat damage removes the tissue faster than the surrounding tissue underneath the heat conduction, which ensures that the coagulation effect is limited to the absorption length of the laser.
Generally speaking, after the first laser irradiation, the skin surface will appear white bubbles. This change indicates that the water in the cells has vaporized, leaving dry protein debris. When these debris are washed away with salt water, obvious skin shrinkage will occur. The skin has a yellowish appearance, and these features are more obvious in thicker skin such as around the mouth. There is significant shrinkage in thinner skin areas such as the upper eyelids without obvious yellowing of the tissue. After three or more irradiations, some yellow-brown dehydrated protein denatured substances can be seen. These substances represent the denatured collagen of the dermal reticular layer, and will appear further thereafter. Carbonization and heat dispersion lead to tissue necrosis.

Treatment principle and scope 1) Treatment principle: The thermal relaxation time of human skin tissue is about 1-2 milliseconds. In order to effectively reduce the scope and degree of thermal damage to surrounding tissue, the laser pulse width must be compressed to less than 2 milliseconds, and the pulse gap should be large. Greater than 2 milliseconds, it is hoped that the surrounding tissue will be cooled during the gap time after the pulse. The carbon dioxide laser therapy device is developed according to such requirements. Because the pulse width of less than 2 milliseconds is ultra-short compared to the pulse width of several tens of milliseconds of ordinary therapeutic devices, this pulsed carbon dioxide laser therapy machine that can output ultra-short pulse width is referred to as a carbon dioxide laser therapy device. The CO2 laser output beam is output through a focusing mirror. The high temperature generated by the focusing point is absorbed by the water in the cells and vaporizes the target tissue, thereby achieving the purpose of treatment.
2) Treatment scope: Plastic surgery: laser skin resurfacing (rough skin, enlarged pores, dull complexion, photodamage, etc.); laser wrinkle removal (crow's feet, forehead wrinkles, Sichuan folds, nasolabial folds); pigmented nevus, epidermal pigment spots (freckles, etc.), Cutting of epidermal tags (all kinds of warts); scar repair (acne scars, hypertrophic scars, linear scars, stretch marks, burn scars, depressed scars, etc.); other applications (xanthoma, syringoma, seborrheic Keratinization, etc.) Dermatology: removal of excess material and treatment of moles and body odor Gynecology: cervical erosion Otology: Removal of nasal polyps Urology: circumcision, genital warts Anorectal: Hemorrhoidectomy Physiotherapy Department: Skin numbness, periarthritis of the neck, periarthritis of the shoulder, arthritis, using beam expander
Carbon dioxide (CO2) 10600 nanometer laser machines have many features in the field of skin beauty, including: 1. **Efficiently remove wrinkles and scars:** CO2 laser can penetrate deep into the skin, stimulate collagen regeneration, and effectively remove wrinkles and scars. 2. **Improve skin texture:** CO2 laser can promote the exfoliation and regeneration of skin epidermis, improve skin texture, and make skin smoother and more delicate. 3. **Wide range of treatments:** CO2 laser is suitable for treating a variety of skin problems, including acne scars, pigmentation, crow's feet, etc. 4. **Quick Recovery:** Although the skin needs a certain amount of time to recover after CO2 laser treatment, the recovery time is shorter compared to traditional surgery. 5. **High safety:** Under the operation of professional doctors, CO2 laser treatment is safe and effective. Treatment parameters can be adjusted according to individual conditions to minimize side effects. 6. **Long-lasting effects:** CO2 laser treatment can usually achieve longer-lasting effects, keeping the skin young and smooth for a period of time. Overall, the CO2 laser 10600 nanometer machine is an effective skin beauty device that can help people improve skin problems and restore young, healthy skin.
After surgery: Ice compress: Reduce postoperative skin reaction. According to the immediate reaction of the skin after different laser treatments, apply cold wet compress or wrap ice cubes in gauze to ice the skin after laser treatment. If the skin color turns white after treatment, the ice compress time is about 30 minutes. If it is only congestion, redness and swelling, the ice compress time is about 30 minutes. Wet compress time is 15 minutes, avoid rubbing the skin during this process.
Replenish skin nutrients: Laser treatment will stimulate the movement of cells and the release of nutrients, but it cannot provide nutrients. In the traditional treatment method, only 0.9% normal saline is used for cold and wet compresses to improve inflammation, edema, burning, and tightness. There is discomfort such as stretch, but the effect is often not ideal. This is because our sebum film is different from the tissue fluid in the body, and the skin needs more professional care products, such as growth factors.
Sun protection: After using laser treatment and beauty technology, the new skin in the treated area will become very sensitive to sunlight. At this time, melanocytes are easily stimulated by light to produce melanin and form pigmentation spots. In addition, new skin is prone to photoaging after exposure to sunlight. Therefore, after laser beauty treatment, sun protection is the key issue. Wear a sunhat, cotton long-sleeved tops and trousers when going out, and use a parasol. It is best to use an anti-UV umbrella, etc.; avoid prolonged exposure to the sun during the strongest hours of the day (10:00 to 16:00). You can also use sunscreen in moderation.
Diet: The role of diet in skin repair cannot be ignored. Protein, fat and sugar are all necessary nutrients for the skin. Vitamins and trace elements can affect the normal metabolism and physiological functions of the skin. For example, B vitamins and folic acid can increase pigment; vitamin C and vitamin A can decrease pigment; Certain trace elements, such as copper, can promote the production of melanin. Therefore, after laser surgery, you should avoid eating foods containing copper and B vitamins, eat less spicy foods, and eat more foods rich in vitamin C and vitamin A. For example, eat more fruits, vegetables, and foods rich in trace elements such as iron and zinc, such as lean meat, fish, beans, Chinese cabbage, radishes, etc., and pay attention to drinking more water. to promote skin repair.
