Laser whitening has few side effects, and the main side effect is skin burn caused by improper operation during operation. If beauty lovers choose to go to a regular medical beauty hospital, use more accurate laser equipment and choose a skilled doctor to do laser whitening surgery, skin burns can be avoided, and the postoperative effect is more obvious and safer. In addition, if beauty lovers clean their faces, apply repair cream on time, do a good job of sun protection and avoid sun exposure, skin pigmentation caused by improper postoperative care can also be avoided.
