CO2 fractional laser uses RF tube and its principle of action is focal photothermal effect. It utilizes the focusing photothermal principle of laser to generate an array like arrangement of smiling light that acts on the skin, especially the dermis layer, thereby promoting the generation of collagen and the rearrangement of collagen fibers in the dermis. This treatment method can form multiple three-dimensional cylindrical smile injury nodules, with undamaged normal tissue around each smile injury area, prompting the skin to initiate repair procedures, stimulating a series of reactions such as epidermal regeneration, tissue repair, collagen rearrangement, etc., enabling rapid local healing.
CO2 dot matrix laser is commonly used in skin repair and reconstruction to treat various scars. Its therapeutic effect is mainly to improve the smoothness, texture, and color of scars, and alleviate sensory abnormalities such as itching, pain, and numbness. This laser can penetrate deep into the dermis layer, causing collagen regeneration, collagen rearrangement, and proliferation or apoptosis of scar fibroblasts, thereby causing sufficient tissue remodeling and playing a therapeutic role.
