Laser eyeliner uses the instantaneous high energy of laser to make the irradiated pigment particles expand and rupture due to energy absorption, and some of them are split into smaller particles and discharged from the body, and some of them are swallowed by the human body and discharged through the lymphatic system, so as to achieve the effect of cleaning the pigment laser eyeliner without causing damage to normal skin and hair around. Laser eyeliner washing is convenient, painless and effective, leaving no scars, thus ideally repairing failed eyebrows and eyeliner.
