Facial hair can be removed permanently by means of laser.
By reasonably adjusting the laser wavelength energy pulse width, it passes through the surface layer of the skin and reaches the hair follicle at the root of the hair, the light energy is absorbed and converted into heat energy that destroys the hair follicle tissue, thus the hair loses its regenerative ability and achieves the effect of permanent removal, without damaging the neighboring tissues, and there is generally no obvious skin tingling and other discomforts after the operation. However, laser treatment usually can not achieve the effect of permanent removal once, need multiple treatments, the specific number of times vary from person to person.
For people who have had facial hair removal, it is important to pay attention to good sun protection after the operation and avoid local stimulation or scratching. In addition, for the increase in hair caused by disease factors, such as polycystic ovary syndrome, or external use of hormonal drugs and other causes of hair increase, need to actively treat the primary disease, stop using the relevant drugs.
For specific need to go to the regular medical institutions, under the guidance of the doctor to choose the appropriate treatment, in order to obtain the best therapeutic effect.
