Treatment of surgical scars with CO2 fractional laser
Post-surgical scarring is a disfiguring manifestation left behind during the wound healing process. For example, the painful psychological shadow caused by trauma, thyroidectomy, giant pigmented nevus, etc. on exposed areas such as face and neck, especially for female patients. Then, for post-surgical scarring, topical medications to prevent scar growth, photoelectric treatment (such as CO2 fractional laser, 585/595nm dye laser, plasma laser, etc.), and modified surgical suturing can be used clinically. The literature shows that early interventions for post-surgical scarring, especially early laser intervention, can effectively improve the appearance of scarring, and a general consensus is gradually emerging on numerous literature reports and can effectively improve patient satisfaction.
-The principle of CO2 fractional laser for scar treatment-
In clinical applications, the CO2 fractional laser produces an array of tiny beams that are completely absorbed by the water in the skin tissue of the treated area and vaporized to form multiple columnar structured micro-damage areas, which in turn promotes the initiation of a uniform skin repair process in the form of thermal stimulation for the matrix arrangement of micro-thermal damage in the scar area and promotes the reconstruction of the skin tissue in all layers. In addition, the tissue around the micro-hole can be well maintained during laser treatment, which can effectively avoid laser damage and enhance the treatment effect and safety.
-Advantages of the CO2 fractional laser -
1. For small surgical scars:
Carbon dioxide fractional laser treatment for scar is an outpatient treatment with shorter treatment operation time; short recovery period, most of the wounds can recover within a few days and will not affect normal work and life; less damage to the treated wounds, no obvious bleeding or only a small amount of bleeding.
2. For large scars:
Carbon dioxide fractional laser treatment for large scars does not require skin removal, reduces much surgical pain, significantly shortens surgery and hospitalization time, and provides rapid relief of pain and itching symptoms; following a course of treatment often results in significant improvement in appearance.

Overview of Picosecond Laser & Indications, Parameter Selection and Contraindications
Picosecond laser refers to a laser with an output pulse width at the picosecond level, mainly including 3 working wavelengths of 755nm, 532nm and 1064nm. Due to its extremely short pulse width, picosecond laser can achieve extremely high peak power in an instant, thereby producing photoacoustic effect (or photomechanical effect) on the target chromophore, crushing tattoo dye particles or melanin particles into smaller particles, making them easier to be cleared by pigment-loving cells such as macrophages, and the inflammatory response is lighter. Therefore, picosecond laser is more effective than Q-switched laser in the treatment of tattoos and most pigment-promoting diseases, and has lighter adverse reactions. In addition, through honeycomb focusing lens or holographic diffraction lens, picosecond laser can be focused into uniformly spaced dot beams. Since each micro beam has extremely high peak power, when it exceeds the photodecomposition threshold of the target color base (melanin or hemoglobin), the target color base absorbs energy nonlinearly to produce photodecomposition effect, forming plasma. The plasma continues to absorb laser energy efficiently and expands continuously, and finally produces a burst phenomenon in the epidermis or dermis, leading to the formation of cavitation bubbles, which is laser-induced optical breakdown (LIOB). There is no damage to the tissues around LIOB, and the inflammatory reaction is also very mild. With the occurrence of LIOB, new collagen and elastic fibers may appear in the dermis. The LIOB effect enables the dot-matrix picosecond laser to improve photoaging and acne pitting scars. Compared with ablative dot-matrix laser and near-infrared non-ablative dot-matrix laser, it has fewer adverse reactions and almost no downtime.

"Xiaomi" in laser medical beauty, Chinese new products are concentrated in the market (2)
The laser medical equipment industry is a technology-intensive industry that integrates multiple disciplines. In addition to safety considerations, the effectiveness, accuracy and long-term reliability of the product must also be guaranteed. There are very high technical requirements in the development of devices such as lasers and strong light generators, precise detection and output control of photoelectric energy, design of human-computer interaction software systems, and integrated system integration.
China's laser medical beauty equipment is running wild on the "shortcut"
The performance of the laser determines the quality and power of the output beam of the laser equipment, and is one of the most core components of the laser equipment. The approval of Chinese picosecond lasers is driven by market demand, and is also related to the gradual maturity of the domestic supply chain and the production and manufacturing of core components in China.
