The principle of laser eyeliner washing is to use the high energy emitted by the laser instantly to make the irradiated pigment particles absorb energy, expand and rupture, and some of them are broken into smaller particles and discharged from the body, and some of them are swallowed by the human body and discharged from the body through the lymphatic system, thus sweeping away the pigment.
Laser eyeliner usually needs to be washed 2 to 3 times to achieve the desired effect, and different wavelengths are changed according to different pigment residues to remove it. If you encounter these problems in the future, you can find me. Just click my user name and you can find me.
