HOW IT WORKS

How ACHELESS works.

Contact, control, and microcurrent—explained in the order you use the device.

  1. 01CONTACT

    Fit the device.

    Position the silicone SSP contact points according to the user guide.

  2. 02CONTROL

    Power on. Select a level.

    Hold the power button for 3 seconds. The device starts at Level 4; use + and − to adjust among four levels.

  3. 03SIGNAL

    Follow the session.

    The device delivers low-frequency microcurrent at its contact points. Follow the guide for timing, warnings, and precautions.

The contact-point illustrations and light effects on this site explain placement visually; they do not depict a measured current path or depth. For indications for use, read the product user guide.

WHY THIS MATTERS / EXPERT MATERIALS

Scientific perspectives. Questions still open.

These materials are individual expert opinions, not clinical studies or proof of an effect on sleep, cognition, brain activity, or autonomic function. The letters do not expand the device’s cleared indications for use; consult the user guide for those indications, warnings, and precautions.

SCIENCE / SOURCE NOTES

Science & Research Background.

Research on SSP electrodes and other electrical-stimulation approaches can inform questions about the technology. These publications do not establish that the commercial ACHELESS SSP Black Edition produces a particular clinical, sleep, or neurological outcome.

01 / RELATED ELECTRODE STUDYPEER-REVIEWED · 2025A closer look at silicone SSP electrodes.

A randomized, double-blind study enrolled 30 people with myogenous temporomandibular disorders. It compared a customized conductive silicone SSP electrode with a conventional suction electrode over four weeks.

What the abstract says: Both groups changed on some measured outcomes, but there was no statistically significant difference between groups after the intervention. The published abstract does not identify the commercial Black Edition as the tested device. A PTBRO-affiliated researcher is a coauthor.

02 / BACKGROUND READINGA different device. A wider field.

A 2016 bioRxiv preprint by Boasso and colleagues explored another transdermal electrical-stimulation approach. It was not a study of ACHELESS or its silicone SSP electrodes, and a preprint is not peer-reviewed evidence.
