-Output power: The Proposed device has a power output range of 0.5W-15.0W, similar to Predicate device (K160549); also, similar to Predicate device (K160952): 15W.

-Pulse width: The pulse width of the subject device: 10ms-2.5s, which is identical to the Reference device (K160549); Somewhat different from Predicate device, but within the scope of what Predicate device claims.

-Repetition rate: Repetition rate of the subject device: 0.2Hz-50Hz, which is identical to the Reference device(K160549), Somewhat different from Predicate device, but within the scope of the Predicate device claim.

#### As for BeautyScan Mode

Clinical: Indication for Use claimed by the been covered by Predicate device (K23007) which depends on product performance and this difference does not affect safety and effectiveness.

#### Technology:

The subject device has the same laser classification, wavelength, same operation mode, energy per microbeam) and number of microbeams to achieve its intended use. (Compare with the K230077).

The comparative analysis of core technical parameters is as follows:

-Applicator window in (mm): applicator window of the subject device K23007 is 12:12mm. The minimum applicator window of subject device. The maximal applicator window of subject device is sightly bigger than the predicate device. The subject device has more precise treatment area. But all of them are intended to meet raise different questions of safety and effectiveness than the predicate device. Therefore, it is substantially equivalent.

- Output power of the subject device is 2N, predicate device K230077 is up to 2W. The output power of the subject device is within the range of the predicate device (K23007). All of them are intended to meet clinical needs, and it doesn't raise of safety and effectiveness than the predicate device. Therefore, it is substantially equivalent.

-Pulse width of the subject device is 10ms- 25ms, predicate device K230077 is 3-30ms. The pubject device is within the range of predicate device (K230077). The pulse width is intended to meet clinical needs, and it doesn't raise different questions of safety and effectiveness than the predicate device. Therefore, it is substantially equivalent.

{16}------------------------------------------------

-Repetition rate: repetition rate of the subject device is 0.5-10Hz, predicate device K230077 is up to 18 Hz. The repettion rate of subject device is within the range of predicate device (K230077). The repetition rate is intended to meet clinical needs, and it doesn't raise different questions of safety and effectiveness than the predicate device. Therefore, it is substantially equivalent.

Conclusion: The subject device has the same intended use and operation principle, the technology, design and performance specifications are either identical or substantially equivalent to existing legally marketed predicate devices. The differe and predicate devices do not alter suitability of the proposed device for its intended use.
