Principle : (Semiconductor) Diode laser hair removal is a non-invasive modern hair removal technology, which can destroy hair follicle structure and permanently remove hair without scalding the skin. 810nm : (1).810nm Diode laser ,Has good uniformity, has better penetration, It is also a relatively good wavelength for melanocytes, which is applied to the principle of selective photothermal effect. The melanin of hair follicle is the target color base, which effectively destroys hair follicles and achieves a better hair removal effect. (2) In the case of patients with darker skin, the target tissue and the epidermis have the same color base and compete with each other to absorb the laser, so there may be a risk of epidermal retention heat for dark skin; However, better curative effect can be obtained for patients with lighter skin color. Advantage 1. 2-3 treatments with obviously result. 2. Strong cooling system, 24-hours non-stop working. 3. Wavelength 810nm 4. big screen, easy to operate. 5. With 3 power supply which separately supply power to the laser, condenser and handle refrigerator. Features 1. Can non stoping work 24 hours, 20 millions shots life for longtime used 2. Big power for machine to remove hair in fast time 3. Best cooling system:air cooling&water cooling&sapphire contact cooling&semi-conductor cooling,which ensure the machine work 24 hours without stop. 4.8 kinds of Languages 5.Man/Women Different skin type Parameter setings Package include: 1 * Main Hair removal machine + Accessories Note 1.
