Basing on the selective light absorption theory, we let the diode laser generated by laser hair removal machine pass through the skin surface and penetrate the hair follicles by adjusting the wavelength, energy, and the pulse width to realize the hair removal purpose. In the hair follicle and hair shaft, there are plentiful melanin spreading between the follicle matrix and moving to the hair shaft structure. Once the melanin has absorbed the energy of laser, it will show a sharp rise in temperature and lead to destroy upon the surrounding follicle tissue. In this way, the unwanted hair will be removed completely. 808 freezing point is based on selective solar-thermal dynamics, through adjusting the wavelength, energy and pulse width of the laser through the skin to the hair root hair follicles, the heat energy is absorbed and break down the follicle tissue.The system of quick freezing point hair removal apply for refrigeration protection,It can make the temperature up to -5ºC,It solves a lot difficulties.At the same time , it is safe, quick and permanent technology808nm Diode laser hair removal system used for hair removal and hair permanently reduce. This system can be used for all types of skin (Expected I-VI skin), including sunburn skin. Hair removal process based on the selective principle of field. The method including destroy hair regeneration mechanism, by moving the hair follicle temperature rise to a high enough to destroy the germainal cells, but will not damage skin and surrounding tissue. Refers to the division, germinal cell differentiation of the cells that make up the hair follicles. After the laser effect, consumed by phagocytes out these cells in vitro. 808nm Diode laser hair removal system unique cooling technology, so that you can directly into the hair roots, laser cooling at the same time protect the skin surrounding tissue, improve the patient's comfort.
