    Intended Use

    The Home use hair removal device is an over-the-counter device intended for removal of unwanted hair such as but not limited to small areas such as underarm and facial hair below the chin line and large areas with Fitzpatrick Skin Phototypes I-V.

    Device Description

    The Home use hair removal device is a personal, light-based, hair reduction device intended to be sold over-the-counter directly to the end user. The device provides hair reduction using Intense Pulsed Light technology. It works below the skin's surface and does not involve any cutting or pulling, reducing hair growth with minimal pain. The device is only powered by the external power adapter and its IPL emission activation is by finger switch. The device contains a Xenon lamp and a skin sensor to detect appropriate skin contact. If the device is not properly and fully applied to the skin of the treatment area, the device will not emit light pulses.

    AI/ML Overview

    The provided document is a 510(k) summary for a medical device called "Home Use Hair Removal Device." It describes the device, its intended use, and its comparison to a predicate device to establish substantial equivalence for regulatory clearance. This type of document is not an academic study or a report of clinical trial results directly proving the device meets specific performance criteria for efficacy in the same way a diagnostic AI device would.

    Therefore, the specific information requested about acceptance criteria, study details, sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, and ground truth establishment for a diagnostic AI device is largely not applicable to this regulatory submission for a hair removal device.

    The "performance data" section in this document refers to:

    • Biocompatibility Testing: Ensuring the materials are safe for contact with the human body.
    • Electrical Safety and Eye Safety Testing: Verifying the device's electrical components and light emission are safe according to established standards.
    • Software Verification and Validation: Confirming the software functions as intended and mitigates hazards.

    These are safety and engineering performance criteria, not clinical efficacy metrics for hair removal, which are typically assessed through different types of studies not detailed here. The 510(k) process relies on demonstrating "substantial equivalence" to a legally marketed predicate device, rather than providing independent clinical proof of efficacy against strict, quantitative acceptance criteria for clinical performance like sensitivity or specificity.

    However, I can extract and structure the information that is present, noting where the requested details are not available or not relevant to this type of device and submission.


    1. A table of acceptance criteria and the reported device performance

    Since this is a 510(k) submission for a physical, light-based hair removal device, the "acceptance criteria" are primarily related to safety, electrical performance, and biocompatibility, rather than clinical efficacy metrics like sensitivity or specificity for a diagnostic algorithm. The document states that the device "passed" these tests, implying they met the requirements of the cited standards.

    Acceptance Criterion TypeStandard/Test PerformedReported Device Performance
    BiocompatibilityISO 10993-5 (Cytotoxicity)Passed
    ISO 10993-10 (Irritation & Skin Sensitization)Passed
    ISO 10993-23 (Irritation)Passed
    Electrical SafetyIEC 60601-1, -1-2, -1-6, -1-11Passed
    IEC 60601-2-57, -2-83Passed
    Eye Safety (General Light Source)IEC 62471 (Photobiological Safety of Lamps)Passed
    SoftwareVerification & Validation"All software requirement specifications are met and all software hazards have been mitigated to acceptable risk levels."

    2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

    This information is not provided in the 510(k) summary. The listed "performance data" refers to technical safety tests rather than clinical studies with human subjects and test sets for efficacy measurement. The summary does not provide details on the number of units tested for electrical safety, biocompatibility, or software validation, nor does it specify the provenance of such test data.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

    This information is not applicable and not provided. "Ground truth" in the context of expert consensus is typically relevant for diagnostic devices that interpret complex medical images or data. For a hair removal device, the "ground truth" would be the physical removal of hair, often evaluated in clinical trials which are not explicitly detailed in this 510(k) summary beyond a general assertion of "safety and effectiveness profile that is similar to the predicate device."

    4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

    This information is not applicable and not provided. Adjudication methods are used in studies involving expert review of diagnostic findings to establish ground truth, which is not the focus of the performance data presented here.

    5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

    This information is not applicable and not provided. MRMC studies are specific to evaluating diagnostic algorithms, often with human-in-the-loop components. This device is a standalone hair removal product, not an AI-assisted diagnostic tool.

    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

    This information is not applicable in the context of diagnostic AI. The device itself is a standalone physical product that performs hair removal. The "software verification and validation" addresses the performance of the embedded software, but not as a diagnostic algorithm.

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

    This information is not explicitly detailed for hair removal efficacy as it relates to clinical studies. For the technical performance data provided:

    • Biocompatibility: Ground truth is established by standardized chemical and biological assays that evaluate material interactions with biological systems against predefined acceptable limits.
    • Electrical and Eye Safety: Ground truth is established by physical measurements and tests against the specified limits of the IEC standards.
    • Software: Ground truth is established by predefined software requirements and hazard mitigations, verified through testing.

    8. The sample size for the training set

    This information is not applicable and not provided. This device is not an AI/ML-based diagnostic algorithm that requires a "training set" in the conventional sense.

    9. How the ground truth for the training set was established

    This information is not applicable and not provided for the same reason as point 8.

    Intended Use

    The Home use hair removal device is an over-the-counter device intended for removal of unwanted hair such as but not limited to small areas such as underarm and facial hair below the chin line and large areas such as legs, in patients with Fitzpatrick Skin Phototypes I-V.

    Device Description

    The Home use hair removal device is a personal, light-based, hair reduction device intended to be sold over-the-counter directly to the end user. The device provides hair reduction using Intense Pulsed Light technology. It works below the skin's surface and does not involve any cutting or pulling, reducing hair growth with minimal pain.

If the device is not properly and fully applied to the skin of the treatment area, the device will not emit light pulses.

    AI/ML Overview

    This document describes the regulatory approval for a home-use hair removal device (models T4, T5, T8, T4-01, T5-01, T8-01, T7) based on Intense Pulsed Light (IPL) technology. The FDA's 510(k) clearance process focuses on demonstrating "substantial equivalence" to a legally marketed predicate device, rather than proving absolute safety and effectiveness through extensive clinical trials for de novo devices. Therefore, the "acceptance criteria" and "study" described below are within the context of a 510(k) submission, primarily focusing on non-clinical performance and comparison to a predicate, rather than a clinical efficacy study with human participants.

    Based on the provided text, here's a breakdown of the requested information:

    1. Table of Acceptance Criteria and Reported Device Performance

    The acceptance criteria for a 510(k) are implicitly met by demonstrating substantial equivalence to a predicate device through various tests. The direct "performance data" presented in this document primarily relates to the safety and engineering aspects of the device, rather than its efficacy in hair removal (which is generally inferred from the predicate).

    Acceptance Criteria Category (Implicit 510(k))Specific Test/EvaluationReported Device Performance/Outcome
    BiocompatibilityEvaluation of body-contacting components according to ISO 10993-1. Specific tests:Passed:
    - ISO 10993-5: Tests for In Vitro Cytotoxicity- Tests passed, indicating no significant cytotoxic effects.
    - ISO 10993-10: Tests for Irritation and Skin Sensitization- Tests passed, indicating no significant irritation or skin sensitization.
    Electrical SafetyTesting according to relevant IEC 60601 series standards (e.g., IEC 60601-1, IEC 60601-1-2 EMC, IEC 60601-1-6 Usability, IEC 60601-1-11 Home Healthcare, IEC 60601-2-57 Non-laser source for cosmetic use, IEC 60601-2-83 Home Light Therapy).Passed:
    - Device meets general requirements for basic safety and essential performance.
    - Complies with electromagnetic compatibility (EMC) requirements.
    - Meets usability requirements.
    - Complies with standards for home healthcare and home light therapy equipment.
    Eye SafetyTesting according to IEC 62471: Photobiological safety of lamps and lamp systems.Passed:
    - Device meets photobiological safety standards for its light emission. (This is critical for a device using IPL, as misuse or faulty operation could cause eye damage.)
    Software Verification & ValidationDocumentation and testing for a moderate level of concern software.Passed:
    - All software requirement specifications are met.
    - All software hazards have been mitigated to acceptable risk levels.
    Functional EquivalenceComparison of technological characteristics (Wavelength range, Energy medium, Energy density, Spot size, Pulse duration, Pulsing control, Delivery device, Indications for use, Location for use) to the predicate device (K210311)."Same intended use, mode of action and similar operational characteristics." Minor differences in spot size, pulse duration, and display are noted but deemed not to "affect or change the intended use of the device" or raise safety/efficacy issues. (Specific numerical comparisons are in the document's comparison table). The device also includes a skin sensor to detect appropriate skin contact for light emission, similar to predicate devices.
    Safety and Effectiveness ProfileBased on all performance data."Safety and effectiveness profile that is similar to the predicate device."

    2. Sample Size Used for the Test Set and the Data Provenance

    • Sample Size for Test Set: The document does not specify sample sizes for human subjects for efficacy testing. The tests conducted (biocompatibility, electrical safety, eye safety, software V&V) are typically in vitro or engineering tests and do not involve "test sets" in the clinical trial sense with human participants. For functional equivalence, the "samples" are the device models themselves (T4, T5, T8, etc.) and a comparison is made to the predicate device's specifications.
    • Data Provenance: The document does not explicitly state the country of origin for the data itself, but the applicant (Shenzhen Mareal Tech Co., Ltd) is based in China. The data would have been generated from laboratory and engineering tests, likely conducted at the manufacturer's facility or certified testing labs. The data is retrospective in the sense that it supports a pre-market notification for a device that has already been developed and tested. There is no mention of prospective clinical trials in this 510(k) summary.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts

    This question is not applicable in the context of this 510(k) submission. "Ground truth" for medical device performance (like hair removal efficacy) is typically established through clinical data, often involving expert assessments (e.g., dermatologists or image analysis). However, for a 510(k) of a device like this, the "ground truth" for the safety and basic functionality is established by adherence to recognized international consensus standards (like IEC and ISO standards) and engineering principles, which represent the collective expertise in device design, safety, and testing. There's no mention of expert radiologists or similar clinical experts establishing ground truth for efficacy in this document, as the submission relies on substantial equivalence to a predicate.

    4. Adjudication Method for the Test Set

    Not applicable. Adjudication methods (like 2+1, 3+1) are used in clinical studies involving human readers or evaluators where there might be subjective interpretations of results. This 510(k) relies on objective engineering and performance data against set standards, not subjective assessments requiring adjudication.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

    Not applicable. This device is a direct-to-consumer home-use hair removal device. It does not involve "human readers" or "AI assistance" for interpretation of medical images or data. Therefore, an MRMC study is not relevant to proving its substantial equivalence.

    6. If a Standalone (i.e. algorithm only without human-in-the loop performance) was done

    Not applicable. This is a physical device, not an AI algorithm.

    7. The Type of Ground Truth Used

    The "ground truth" for this 510(k) submission is primarily based on:

    • Compliance with recognized international consensus standards: For electrical safety (IEC 60601 series), biocompatibility (ISO 10993 series), and photobiological safety (IEC 62471). These standards represent established scientific and engineering principles for safety.
    • Software verification and validation outputs: Demonstrating the software meets specifications and mitigates hazards.
    • Comparison to the predicate device's specifications: The predicate device, having already been cleared, serves as a benchmark for acceptable performance characteristics (energy density, pulse duration, wavelength, etc.) for a home-use IPL hair removal device.
    • Functional testing: Implied by the successful completion of the safety tests and the comparison to the predicate, ensuring the device operates as intended.

    There is no mention of "expert consensus" on hair removal efficacy, pathology, or outcomes data from a clinical trial, as those are typically not primary requirements for a 510(k) where substantial equivalence to a cleared predicate is claimed.

    8. The Sample Size for the Training Set

    Not applicable. This device is not an AI algorithm that requires a "training set."

    9. How the Ground Truth for the Training Set Was Established

    Not applicable, as it's not an AI algorithm.

    Intended Use

    The Home use hair removal device is an over-the-counter device intended for removal of unwanted body hair and/or facial hair.

    Device Description

    The Precise Touch Pro Home use hair removal device is a personal. light-based, hair reduction device intended to be sold over-the-counter directly to the end user. The device provides hair reduction using Intense Pulsed Light (IPL) technology to perform hair removal. The device mainly consists of IPL main body, AC adapter and device stand three parts and it is only powered by the external power adapter, as well as the treatment window located in the main body which is the source of optical radiation, namely a Xenon flashlamp and the built-in skin sensor to detect the body skin area. If the device is not properly applied to the expected treatment area (in full contact with the skin), the device cannot be automatic triggered a pulse emitting.

    AI/ML Overview

    The provided text does not contain information about acceptance criteria for a device's performance, nor does it describe a study proving the device meets specific performance criteria related to medical effectiveness (e.g., hair reduction efficacy percentages).

    The document is a 510(k) summary for a home-use hair removal device (Precise Touch Pro) and focuses on demonstrating substantial equivalence to predicate devices, not on proving de novo clinical efficacy against specific acceptance criteria.

    The "Performance Data" section primarily addresses:

    1. Biocompatibility Testing: Ensuring the materials are safe for body contact.
    2. Electrical Safety and Eye Safety: Compliance with relevant international standards.
    3. Software Verification and Validation: Assuring software functions correctly and mitigates risks.

    These are safety and engineering performance aspects for regulatory compliance, not efficacy performance related to the device's intended use of hair removal in terms of, for example, a targeted percentage reduction in hair.

    Therefore, I cannot provide the requested information regarding acceptance criteria for device performance and a study proving it, as that information is not present in the provided text.
