The way this laser works is that it sends single-beam lasers of specific wavelengths to the epidermis and dermis of the skin. Fractional laser targets the surface of the skin by creating thousands of ultra-thin columns of beams. Each column of the laser beam is called the MTZ region or fine heat treatment.
Fractional laser is the interface between ablative and non-ablative lasers, and only part of the skin is exposed to radiation. While the destructive laser only affects the epidermis of the skin while the non-destructive laser only affects the dermis layer of the skin, the fractional laser affects the epidermis and dermis simultaneously. In fact, fractional co2 laser is a kind of deep peeling of the skin and finally eliminates dullness and dead skin that cannot be repaired and has the potential to regenerate and repair the skin.
