IPL Technology: Intense Pulsed Light (IPL) allows the melanin in the hair follicle to absorb enough energy to destroy the structure of the hair follicle and prevent the hair follicle from regenerating. After repeated use, the hair follicles gradually shrink to achieve the effect of inhibiting hair growth.Different Skin Types: The Intense Pulsed Light Removal System is especially effective for dark blonde, brown or black hair. Like any hair removal device, laser epilators are not suitable for red, light blonde, gray or white hair. In addition, this product is not suitable for dark skin.2 DIFFERENT MODES: manual mode (flash mode) is mainly used for hair removal of small areas, such as bikini line, armpits, lips; automatic mode (sliding mode) can be used for large hair removal areas, such as legs, abdomen and back.5 Energy level: Pulsed light hair removal can be set from 1 (lowest) to 5 (highest) .Choose the energy level according to your needs. The higher the level, the stronger the energy, the better the hair removal effect (first use, recommended to use level 1).
