The Handheld Diode Laser for Hair Removal is an over-the-counter device intended for adjunctive use with shaving for hair removal sustained with periodic treatments. Handheld Diode Laser for Hair Removal is also intended for permanent reduction in hair regrowth defined as a long-term, stable reduction in hair counts following a treatment regime. permanent hair reduction is defined as long term, stable reduction in the number of hairs regrowing when measured out to 6, 9, and 12 months after the completion of the treatment regimen.

Device Story

Handheld Diode Laser for Hair Removal (SD-BD01) is an OTC semiconductor diode laser system for home-use hair removal. Device emits 808nm infrared light; operates on principles of selective photothermolysis to target melanin in hair shafts, damaging follicular epithelium while sparing surrounding tissue. User-operated; device requires manual application to skin. Output is laser energy at selectable fluence levels (5.5–21.2 J/cm²). Healthcare providers do not operate device; users follow provided labeling and skin tone charts to determine suitability. Benefits include sustained hair removal and permanent reduction in hair regrowth through periodic treatment regimens.

Clinical Evidence

No clinical data. Bench testing only, including verification of design specifications, laser safety (IEC 60825-1), electrical safety (IEC 60601-1), EMC (IEC 60601-1-2), and biocompatibility (ISO 10993). Usability/label comprehension study conducted with 23 participants to confirm user ability to follow instructions and safety warnings.

Handheld Diode Laser for Hair Removal is also intended for permanent reduction in hair regrowth defined as a long-term, stable reduction in hair counts following a treatment regime. permanent hair reduction is defined as long term, stable reduction in the number of hairs regrowing when measured out to 6, 9, and 12 months after the completion of the treatment regimen.

#### న్. Device Description

The Handheld Diode Laser for Hair Removal is an Over-The-Counter device intended for adjunctive use with shaving for hair removal sustained with periodic treatments. The device is also intended for permanent reduction in hair regrowth defined as a long-term, stable reduction in hair counts following a treatment regime permanent hair reduction is defined as long term, stale reduction in the number of hairs regrowing when measured out of 6, 9, and 12 months after the completion of the treatment regimen.

The Handheld Diode Laser for Hair Removal is a semiconductor diode laser system that delivers infrared light at a wavelength of nominally 808nm.

Laser hair removal is based on the principles of selective photothermolysis (SPTL): a combination of the appropriate laser wavelength, pulse duration, and fluence can obtain optimal effect on a targeted tissue with minimal effect on surrounding tissue.

Wavelengths of 808 nanometers (nm) are widely used in hair removal treatment, it is selectively absorbed by melanin in the hair shaft, damaging the follicular epithelium, and further causes hair loss, while the competing chromophores (oxyhemoglobin and water) absorb less energy at these wavelengths.

- > Performance Testing for Spot Size Accuracy.

A Usability/Label Comprehension Study was conducted.

Two smaller groups out of these participants were chosen to participate in a usability study in which the actual product along with its labeling would be tested.

The first group of 13 participants consisted of 7 females, 6 males and their ages ranged from 19-71 years. Two participants with dark skin tone and one participant with blond hair were included in this group. It was explained to them what the study was all about and then were asked (two at a time) to pretend that they had just purchased the product and were to use it for the first.

{6}------------------------------------------------

The tester allowed ample time for the users to read/study the labeling, include information on retail box, name plate and Instruction Manual Rev: V 1.02, completely while recording questions and answering them. Then the actual use of the product was observed, remarks and questions were recorded.

Then we revised the Instruction Manual form Rev: V 1.03 according with the question from the tester.

A second group of 10 participants was chosen for a second test. There were 5 females, 5 males and their ages ranged between 19 and 73 years.

Again, after allowing ample time to read and study the Instruction Manual Rev: V 1.03, the questions asked came down to only 2 and they were not pertaining to safety or operation.

Results

For the first groups,

- 1) All participants understood the "Skin Tone Chart", Warnings, Indications and Contraindications;
- 2) Three user refused to use the product after reading the determination as "Skin Tone Chart" and
- Indications, because skin tone and hair color;
- 3) 9 of the remaining 10 users had questions.

The inputs of the first groups needed some changes and additions to the Instruction Manual (Rev: V 1.02). For the second groups, the result showed that all (100%) participants were able to properly use the device and properly clean it with the labeling submitted.

The inputs of the second test groups did not warrant any more changes and additions to the Instruction Manual (Rev: V 1.03).

- 8. Clinical Test Conclusion
No clinical study is included in this submission.
