The SHASER HRS2 Hair Removal System is an over-the-counter device intended for removal of unwanted hair. It is also intended for permanent reduction in unwanted hair. Permanent hair reduction is defined as the long-term stable reduction in the number of hairs re-growing when measured at 6, 9, and12 months after the completion of a treatment regimen.
The SHASER HRS2 Hair Removal System is a personal, light-based, hair reduction system intended to be sold over-the-counter directly to the end user. The device provides permanent hair reduction as defined below using Intense Pulsed Light (IPL) technology.
The SHASER HRS2 Hair Removal System consists of a powered base unit and a tethered hand piece from which the IPL flashes are delivered to the patient's skin. The system will be sold with light carring a cloth, and user's manual.
Here's a breakdown of the acceptance criteria and the study details for the SHASER HRS2 Hair Removal System, based on the provided 510(k) summary:
1. Acceptance Criteria and Reported Device Performance
| Acceptance Criteria (Definition of Permanent Hair Reduction) | Reported Device Performance (Average Hair Reduction) |
|---|---|
| Long-term stable reduction in the number of hairs regrowing when measured at 6, 9, and 12 months after the completion of a treatment regimen. | At 3 months: 37% average hair reduction |
| At 6 months: 48% average hair reduction | |
| At 12 months: 66% average hair reduction |
Note: The acceptance criteria itself is qualitative ("long-term stable reduction"). The clinical trial aims to demonstrate that the device achieves this by reporting quantitative hair reduction percentages at specified time points.
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size: Not explicitly stated as a single number, but the study was conducted on "a population of approximately 50% female and 50% male subjects from diverse demographic sub-groups." The specific number of subjects is not provided, but it implies a cohort designed to represent a diverse user base.
- Data Provenance: The document does not specify the country of origin of the data. It indicates a "clinical trial was conducted," suggesting prospective data collection.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This information is not provided in the given document. The summary focuses on hair count measurements without detailing expert involvement in establishing ground truth for the hair counts.
4. Adjudication Method for the Test Set
This information is not provided in the given document.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was done
No, an MRMC comparative effectiveness study was not done. This type of study typically involves comparing human readers' performance with and without AI assistance, which is not applicable to this hair removal device.
6. If a Standalone (i.e. algorithm only without human-in-the loop performance) was done
This concept is not applicable to the SHASER HRS2 Hair Removal System. This device is a physical, light-based hair removal system, not an algorithm or AI system that would have a standalone performance measured independently of a human user. The "performance" here refers to the physical outcome of hair reduction on human subjects.
7. The type of ground truth used
The ground truth used was hair counts. These were "taken before treatment and 3, 6, and 12 months following the final treatment." This is a direct, objective measurement for assessing hair reduction.
8. The sample size for the training set
This information is not applicable as this device is a physical light-based hair removal system, not an AI/ML algorithm that would undergo training on a dataset.
9. How the ground truth for the training set was established
This information is not applicable for the reasons stated above.

Device Description:
The SHASER HRS2 Hair Removal System is a personal, light-based, hair reduction system intended to be sold over-the-counter directly to the end user. The device provides permanent hair reduction as defined below using Intense Pulsed Light (IPL) technology.
The SHASER HRS2 Hair Removal System consists of a powered base unit and a tethered hand piece from which the IPL flashes are delivered to the patient's skin. The system will be sold with light carring a cloth, and user's manual.
Intended Use:
The SHASER HRS2 Hair Removal System is an over-the-counter device intended for removal of unwanted hair. It is also intended for permanent reduction in unwanted hair. Permanent hair reduction is defined as the long-term stable reduction in the number of hairs re-growing when measured at 6, 9, and12 months after the completion of a treatment regimen.
Performance Data
The device complies with the following U.S. Food and Drug Administration performance standards: 21 CFR § 1040.10 & 1040.11. A clinical.trial was conducted to demonstrate the safety and effectiveness of the SHASER HRS2 Hair Removal System for over the counter use for permanent reduction in hair regrowth defined as a long-term, stable reduction in hair counts following a treatment regime. In a clinical trial, test sites including arm, leg, chest, abdomen, bikini line and underarms were treated 3 times at 2 week intervals on a population of approximately 50% female and 50% male subjects from diverse demographic sub-groups. Hair counts were taken before treatment and 3, 6, and 12 months following the final treatment. The results showed an average reduction of 37%. 48%, and 66% at each respective end point.
Substantial Equivalence
Technological Characteristics and Comparison to Predicate Device(s);
The SHASER HRS2 Hair Removal System is substantially equivalent to the Shaser IPL Hair Removal System K103560 and the Home Skinovations Silk'n Flash N Go K103184
The SHASER HRS2 Hair Removal System has similar intended use and indications, and same technological characteristics, and principles of operation as the predicate devices. Any minor differences between the SHASER HRS2 Hair Removal System and its predicate devices raise no new questions of safety or effectiveness nor change the device's intended therapeutic effect in comparison to its predicates. Performance data demonstrate that SHASER HRS2 Hair Removal System is as safe and effective as its predicate devices for the stated indications. Thus, the SHASER HRS2 Hair Removal System is substantially equivalent.
