Ultra-pulse carbon dioxide fractional laser in the treatment of surgical scars

Post-surgical scars are disfiguring manifestations of wound healing. For example, the painful psychological shadow caused by trauma, thyroidectomy, giant pigmented nevus, etc. on exposed parts such as the face and neck, especially for female patients. For postoperative scars, clinically, external use of drugs to prevent scar hyperplasia after surgery, photoelectric therapy (such as carbon dioxide fractional laser, 585/595nm dye laser, plasma laser, etc.), improved surgical suture methods, etc. Literature shows that early intervention measures for postoperative scars, especially laser early intervention, can effectively improve the appearance of scars, and a general consensus has gradually formed in foreign literature reports, and can effectively improve patient satisfaction.

-Principle of carbon dioxide fractional laser treatment of scars-

In clinical application, the carbon dioxide fractional laser can generate array-like micro-beams. After acting on the skin surface, the laser energy can be completely absorbed by the water in the skin tissue of the treatment area and vaporized to form multiple columnar micro-damage areas. Furthermore, aiming at the matrix-like arrangement of micro-thermal injury at the scar site, it promotes the start of the uniform skin repair program in the form of heat stimulation, and promotes the reconstruction of each layer of skin tissue. Moreover, the tissue around the microhole can be well maintained during laser treatment, which can effectively avoid laser damage and improve the treatment effect and safety.
