Indications for Use

The BEAGANK 4T PLUS is a handheld portable device for over-the-counter aesthetic use including facial and neck stimulation or body skin stimulation.

Device Story

Handheld portable aesthetic device; uses rechargeable lithium-ion battery; features four metal electrode pads on head. Operates by delivering transcutaneous electrical nerve stimulation (TENS) to face, neck, and body skin. Requires conductive media (wet cotton pad with purified water or cosmetic liquid) for pulse generation. Includes scalp and small attachments. User-operated for cosmetic purposes. Output consists of four selectable operational modes with varying electrical pulse parameters. Healthcare providers do not interact with output; device is for consumer self-use. Benefits include aesthetic skin stimulation.

Clinical Evidence

No clinical data. Bench testing only. Performance verified via electrical safety, electromagnetic compatibility, and biocompatibility testing.

Technological Characteristics

Handheld aesthetic TENS device; ABS plastic housing; internal rechargeable lithium-ion battery; Type BF patient leakage isolation. Four metal electrode pads. Connectivity: standalone. Sterilization: non-sterile. Electrical safety: IEC 60601-1, IEC 60601-1-2. Biocompatibility: ISO 10993-5, 10993-10, 10993-23.

Indications for Use

Indicated for over-the-counter aesthetic use including facial, neck, and body skin stimulation for general users.

Regulatory Classification

You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. {1}------------------------------------------------ Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).
