Laser hair removal does not usually burn the skin, but it may burn the skin if something unusual happens during the procedure. Normally, laser hair removal will not burn the skin. Laser hair removal is based on the principle of selective photothermal, adjusting the appropriate laser light, penetrating the skin surface, directly acting on the hair follicle, so that it loses the ability to regenerate hair. However, if the laser parameter is set wrongly or the operation is not done properly, it may cause the laser energy to be too high or stay in the local skin for a long time, thus burning the skin. It is recommended that people who need to take laser hair removal, go to a regular hospital, under the guidance of the doctor, make relevant plans, and cooperate with the doctor to regulate hair removal.
