Fractional CO2 laser works by delivering a concentrated beam of light that is absorbed by the water in the skin cells. The energy from the laser heats up and vaporizes the targeted skin, creating tiny columns of treated tissue. These columns are surrounded by healthy tissue, which allows for faster healing and minimal downtime. It is commonly used for skin resurfacing, treating wrinkles, scars, and other imperfections. The treatment is safe and effective, with minimal side effects such as redness and swelling that subside within a few days. Multiple sessions may be required to achieve optimal results.
Non-ablative 1550nm erbium-glass fractional laser acts on skin by microscopic laser beams under the operation mode of static stamp or dynamic rolling. Energy from the laser creates micro-columns of heat in the skin creating new skin cells and increasing collagen production. Compared to the CO2 laser, 1550nm laser claims to have improved safety profile for patients of darker skin type. And it tends to target more superficial problems like fine lines, wrinkles and stretch marks with short downtime.
