Under the condition of ensuring that the skin is not damaged, the laser pulses on the skin with focused micro-pixels, which produces thermal shock to tiny areas, and scar tissue is pressed into powder from particles, and then these cell fragments jump up and increase, and are finally absorbed and removed by macrophages, which promotes skin healing and scars fade away.
