How to Select a Microcurrent Device


This brief essay is intended to help professionals who want to get involved with the practice of microcurrent therapy, or microcurrent facial rejuvenation, in wading through the often confusing information encountered when investigating this subject.

By its very nature, electro-therapy tends to be difficult to understand for most health and esthetic professionals. Few have training in electronic theory and parameters, physics or the Universal Laws of energy that clinical success or failure is based upon. Most manufacturers of clinical stimulation devices offer very limited training and instruction, based on simplistic and relatively ineffective techniques of application.

I’m sure that the intentions of the people who write electro-therapy training manuals is to keep the information as simple as possible, but the vast majority of the instructions given consist of placing probes or pad electrodes right over locally painful zones and stimulating these with currents that are usually way too strong for optimal response. In the case of facial rejuvenation training programs, almost all that I have seen involve localized techniques targeted to facial muscles and tissues only.

While these are simple concepts to grasp, this is not what will actually provide the most satisfactory and long-lasting results.

Microcurrent devices are those that output therapeutic currents regulated in the millionth of an amp, or microcurrent, range. The success and popularity of microcurrent electro-therapies are based on a history of superior patient responses, compared with conventional milliamp devices. This is due to the fact that most of the human body’s innate electrical activity occurs in the pico (trillionths) and nano (billionths) of an amp range, and in some cases reaches the microamp range. Readjustment of these extremely subtle fields is better accomplished with currents that are just slightly higher than the innate currents. Advanced Aesthetics

Quality microcurrent devices are also superior due to the more precise and targeted treatment techniques they are capable of performing rather than the old “slap on the pads, set the timer and leave the room” style of conventional stimulators.


The high-intensity milliamp currents output by most electro-therapy devices are truly an ‘overkill’ response in most clinical cases, although some acute conditions presenting muscle spasm, gross edema and severe pain do require this overkill response for first aid purposes. Even when milliamps are useful, it is advisable to immediately follow with gentle microcurrents to ease the body down from the distortions induced by the high intensity current intervention. Therefore, a device that offers both milli and microcurrents through the same output channels, in sequence, will be most clinically useful for acute pain and injury conditions. This would allow you to give a patient brief milliamp treatment followed by a longer period of microcurrents, preferably without you having to come back to the treatment room to change parameters.


One of the most exciting and effective innovations in microcurrent technology in recent years is the combination of microcurrent with simultaneous color light therapy. Microcurrents are usually applied in the low frequency range that effectively targets pain relief and healing of the muscles, fascia, nerves and tendons of the physical body. Color light consists of the highest frequency stimulations that are safe for long term application to the body. Wavelengths of the visible light spectrum (ranging from violet at 400 nm up to red at 700 nm) have been shown to activate cellular healing responses, improve organ and glandular health and help with healing of emotional imbalances. Color light therapy is also recognized for its great value in promoting rejuvenation and anti-aging benefits, with many benefits over microcurrent alone.
