Permanent hair reduction is defined as the long-term, stable reduction in the number of hairs regrowing when measured at 6, 9, and 12 months after the completion of a treatment regime. #### 5. Device Description Diode Laser Hair Removal adopts Gold standard 808nm semi-conductor laser, based on selective photothermolysis principle, through specific wavelength, penetrate epidermis into dermis, optical energy was absorbed and translated into heat energy with restraining hair follicle tissues, and produce photothermal effect. It takes laser energy in hair follicle with rich in melanin, surrounding tissues absorb less even no energy, reach to restrained melanin of hair follicles and remove hair. Meanwhile, don't hurt around tissues and virtually pain-free remove surplus hair; eventually, reach to permanent Hair Removal. The Diode laser therapy device utilize a semiconductor diode with invisible infrared radiation as a laser source to emit 808nm wavelength laser which is absorbed by melanin. The laser power is delivered to the treatment area via laser handpiece. The emission laser is activated by a foot-switch. #### 6.

Therefore, this difference will not affect the safety and effectiveness. ## Analysis 2: The proposed device is difference in Pulse Duration with the predicate device. The frequency of the proposed device is within the range of that of the predicate device, which can justify that the difference in the parameter of Pulse duration will not raise new safety issues of the proposed device. In addition, we also found a reference device (K181019), which has the same intended use as the reference device. The Pulse Duration of the reference device is 30-200 ms, which is similar to the proposed device's pulse duration, so this difference will not affect the effectiveness of the device. In summary, this difference will not affect safety and effectiveness of the proposed device. # Analysis 3/4: The proposed device is different in dimension and weight from the predicate device. However, the dimension and weight difference are just in physical specification and this difference will not raise any issues in safety and effectiveness. By complying with AAMI/ANSV/ES 60601-1, the mechanical performance of the proposed device is determined to be accepted. Therefore, this difference will not affect safety and effectiveness of the proposed device. # 10. Substantially Equivalent (SE) Conclusion The conclusions drawn from the nonclinical tests demonstrate that the device is as safe, as effective, and performs as well as or better than the legally marketed device (K210663).
