QLHF-02 adopts laser blasting effects & the theory of selective absorption. Then high energy laser pulses will act on the pigment tissue, after the laser shock, the pigment tissue will dilate rapidly, the thermal relaxation time of laser pulses is much shorter than that of melanoma & tattoo, so the pigment tissue will generate mechanical oscillation wave & then be broken up after absorbing laser energy. The fragmentized pigment granuale will be excreted to the outside of the body through metabolism & phagocytosis of macrophages. Thus the pigment will be removed. Meanwhile, the laser beam can penetrate into corium layer to activate the tissue, accelerate cell regeneration in order to get the following effects: wrinkle removing, skin whitening, skin rejuvenation & skin quality Improving
