Microcurrent uses electrical current measured in microamperes, millionths of an amp. It stays below one milliamp, low enough that it does not make muscles contract and is usually not felt at all (Iijima & Takahashi, 2021). Its range sits close to the small currents the body produces on its own (Wadhwa et al., 2026).
A familiar TENS unit is built to be felt. Microcurrent is built to be faint, closer to a whisper than a shout.
How we use it
Microcurrent is the Current signal in the Three Signals and a part of most of our sessions. We deliver it with the Electro-Acuscope and Myopulse system.
Where the evidence stands
A systematic review found that microcurrent improved shoulder pain and knee pain compared with sham, each in a single small trial, with no serious adverse events. The same review found a clinically meaningful placebo response, a reminder of how much setting and expectation shape results (Iijima & Takahashi, 2021). As well, a 2026 review of eleven studies on wound healing and scars found possible benefits, with results that were inconsistent across protocols, populations, and small samples (Wadhwa et al., 2026). The evidence is promising and uneven.
