The LED Therapy Device is a surgical device intended for use in dermatologic and general surgical procedures. It utilizes a diode LED as a light source (780-850 nm). The LED light power is delivered to the treatment area via a LED hand piece. The emission LED is activated by a foot switch and a hand piece. The proposed LED Therapy Device is equipped with a light depilation function that is based on the theory of selective photo thermolysis. There is abundant melanin in the hair follicle and hair stem. The melanin is distributed amidst the cells between the hair ball substrate and it can be transferred to the structure of hair stems (such as medulla, cortex, and hair cuticle). The Near infrared light can precisely target the melanin and apply the depilation treatment selectively. After the melanin absorbs Near infrared light energy, the temperature rises, in this way, the surrounding hair follicle tissues are damaged, and the hairs are removed.
