Endo technique, consists of using a laser beam with a wavelength of 1470 nm emitted through an optical fiber inserted into the subdermal tissue in order to reduce subcutaneous fat and tone the skin through the intense production of collagen. Lately, the 1470 nm wavelength laser has started to be actively used in surgical procedures. Laser equipment with a wavelength close to 1500 nm has its absorption in water as a predominant characteristic generating specific biological effects. These lasers are water-absorbable or water-specific and are mainly used in urology and for endovenous obliteration of veins . The 1470 nm diode laser is able to deeply penetrate into tissues due to its high affinity for water and also acting on fat. All due to it is understood that the richer a tissue is in water and fat, the better it will be. the transmission of this kind of laser and the smaller its dispersion . Therefore, using 1470 nm wavelength in non-surgical endo procedures has become very common nowadays.
