This model BS-IPL-YAG2 system, is a kind of Multifunctional IPL and YAG laser system, that combines the intensed pulse light and Q-switch ND: YAG laser units together. By using IPL technology, it can be used to apply IPL hair removal and IPL skin rejuvenation treatments. The IPL system emits a broad spectrum of intense pulsed light through the professional hand-piece. High quality crystal filters light in useless wavelength range. The light penetrates the tissue and is absorbed by either the blood when treating vascular lesions or the melanin when treating pigmented lesions or for hair removal and then damaging them. The body's natural processes then remove the injured tissue giving the skin a more even and youthful appearance. Q-switch ND:YAG laser unit can be used for tattoo removal and pigment removal. The pigmentation of body can be effectively broken up into pieces and removed by laser instantaneous high energy. Laser at certain wavelength can penetrate epidermis to lesion tissues within the extremely short time, then break up the corresponding chromospheres immediately. The corresponding pigment expands rapidly and explodes into pieces. Part of the pigment will be bounced out from patient's body at the moment, while the other part the pigment will split into the tiny granules that can be engulfed by phagocytes of the body. After the digestion of phagocytes, it can be excluded from the lymphatic system. The pigment of the injured tissues gradually becomes shallow until disappears, while no injured trace will be left on the peripheral normal tissues, for they will not absorb the laser of the fixed wavelength.
