Foot hair can be permanently removed by laser hair removal. Foot hair is more serious, especially in the summer time, conscious of the impact on the aesthetic, but the use of hair removal creams or physical shaving foot hair can only play a temporary removal of the purpose, and through the laser hair removal can achieve permanent results. The principle of laser hair removal is to utilize the photothermal effect of the laser to apply thermal energy to the hair follicles during the anagen phase, destroying the hair follicle structure so as to achieve the purpose of hair removal. However, laser hair removal requires several treatments (3-5 times) to achieve a radical effect, this is due to the fact that hair follicles in the anagen phase can absorb heat energy, and thus be destroyed, while hair follicles in the resting or regression phase can not absorb heat energy well, and thus can not be destroyed. It is recommended to go to a regular medical institution and perform laser hair removal under the guidance of a specialist to avoid adverse consequences such as thermal burns.
