Through the photothermal principle of freezing point laser, the effect of removing beard is achieved by destroying hair follicles, so this method is a permanent method. Freezing point painless hair removal is to absorb the light emitted by optical quantum devices through the principle that body hair pigments absorb light energy. Body hair converts the absorbed light energy into heat energy and transmits it to hair follicles, which destroys hair follicles and makes them shrink, thus achieving the purpose of hair removal, and has no effect on sweat glands. Facial skin with beard is generally blue, and body hair is heavier. When operating, the absorption of light energy will be greater than that of other parts of the body hair, and the thermal sensation will be greater, but it is generally acceptable. It is forbidden to pluck hair before depilation. You can apply cold water after depilation.
2, laser hair removal
Laser hair removal can selectively penetrate into hair follicles and be absorbed by melanin in hair follicles, resulting in selective destruction, degeneration and atrophy of hair follicles, thus achieving the purpose of permanent hair removal. Because the thicker and darker the hair, the bigger the hair follicle and the deeper the melanin, the easier it is to accept the destructive effect of laser, so the better the curative effect; The effect of removing beards is ideal. With the development of laser hair removal treatment, the growth of beard will be slower and thinner, and will eventually be completely eliminated. Different colors of laser light are absorbed by different colors of skin. Laser hair removal method is to use laser energy to decompose and vaporize dye particles, seal blood vessels, and then the dye particles are absorbed by the body and excreted, and the pigment disappears. Because the laser with a certain wavelength is only absorbed by the pigment of the corresponding color, only the diseased cells can absorb this specific laser, while the normal skin tissue is not damaged and does not leave scars, which can achieve the effect of permanent hair removal.
