Every cell in your body runs on ATP — adenosine triphosphate, the molecule that stores and releases the energy powering every cellular process, from muscle movement to tissue repair. How cells produce ATP is so fundamental to biology that the discovery of the enzyme behind it (ATP synthase) was recognised with the 1997 Nobel Prize in Chemistry.
Microcurrent Electrotherapy is built on that same science: support the cell's ability to produce ATP, and you support the body's ability to heal itself.
Microcurrent Electrotherapy (M.E.T.) is a specialised form of electrotherapy that delivers very small electrical currents to the body — measured in microamperes (millionths of an ampere). These gentle currents mirror the body's own natural cellular electrical activity, helping to restore physiological balance at the cellular level.
Unlike TENS units, which use currents strong enough to stimulate nerves and block pain signals, M.E.T. works below the threshold of sensation — roughly 1,000 times weaker than typical TENS therapy. Most users feel nothing at all during treatment.
Research in the 1970s and 1980s established that healthy cells maintain a natural electrical potential in the microampere — or even picoampere — range. When tissue is damaged, this electrical balance is disrupted. The resulting "injury current" is one of the signals that triggers the body's natural repair mechanisms.
M.E.T. therapy delivers currents in this same physiological range — less than 1 milliampere, typically in the microampere range — to replicate and reinforce these natural healing signals.
In a landmark 1982 study, Ngok Cheng and colleagues showed that microcurrent applied within a specific range increased ATP production in skin tissue by up to 500%. Critically, the study also showed that currents outside this range reduced ATP production — which is why the output parameters of a microcurrent device matter so much.
More cellular energy means more resources available for healing, repair, and recovery.

Tissue repair depends on building new proteins — the structural components of skin, muscle, and connective tissue. The same 1982 research demonstrated that microcurrent significantly stimulates protein synthesis, supporting faster recovery. And again, the current must be precisely calibrated: too little does nothing, too much reduces effectiveness.
Cells depend on the constant, efficient exchange of substances — amino acids, calcium, sodium, potassium — across their membranes. Microcurrent has been shown to enhance this molecular transport, supporting:
M.E.T. promotes galvanotaxis — the directed movement of white blood cells toward injury and infection sites, an important part of the immune response. Research also suggests that many harmful bacteria struggle to thrive in the electrical environment created by microcurrent therapy, which may contribute to its effectiveness in chronic wound healing.

Microcurrent therapy isn't a miracle cure. We'd rather be straightforward about what it is:
