Because Hulle cell which has the cell have possibility to growth containing stem cells and transient amplifying, TA cells is remained between treatment area. Matter will be damaged in direct proportion to its value. The speed of skin rejuvenation is in direct to density and quantity of TA and stem cell. So the side effect after treatment is very low or not occurred comparing old type of laser device like CO2 laser.
