CO2 Laser have a high absorption in water and low absorption in melanin & haemoglobin. It generates heat to vaporize the water and produce ablation in target area accurately. Refine CO2 fractional laser can deliver multiple laser beams in fractional pattern which creates an MTZ (Micro Thermal Zone). The laser pulses penetrate deep int the dermis to produce vaporization, coagulation and carbonization of skin tissue. Undamaged skin between fractional laser beams acts as a ‘heal server’ and expediates skin recovery process. Thus, fractional laser is an optimal solution for complete skin resurfacing and skin rejuvenation.
