using the light blasting effect, the high-intensity laser penetrate the epidermis and can reach the pigment clusters in the dermis layer. the energy has a short time of action and the energy is extremely high, the pigment clusters will quickly expand and explode after absorbing the high energy in an instant. the picosecond laser with ultra-short pulse width can effectively produce p-mechanical effects and break the pigment particles into small fragments. compared with nano-scale q-switched laser, picosecond laser only needs lower energy to achieve the effect. it takes less number of treatment courses to achieve better treatment effect. the shorter the pulse width, the weaker the effect of converting light into heat. instead,so picoseconds can effectively crush the pigment particles, resulting in better pigment removal..syi
