Its the current in pico passing through silver particles in gloves.
Look into similar mechanism by Robert O Becker for terrible infection and finger regeneration.
http://www.rexresearch.com/becker/becker1.htm |
I'm not referring to the silver gloves - which are only used to conduct the current, not perform healing. (Although I do recognise the effects of silver as a healing medium in topical creams).
I'm talking about the various waveforms said to be used in different machines. At first we were told that microcurrent must be a square waveform to be real microcurrent for regenerative use - but Neutrosis states that they use second generation microcurrent. How this differs from Beautiful Image or CACI, I don't know. |

Thanks for the link - there's some good, easy to understand info there.

Sawtooth

My point is that manufacturers don't always divulge which type of wave form or hz the machine uses - so it becomes difficult to compare devices. With such a relatively simple technology, I still don't know why some machines cost thousands and some cost under $20 when all they're doing is delivering a minuscule current. |

I don't know how accurate that wikepedia article is really. Current is current, the main difference would be single current or not, and steady or pulsing. The effects of these differences I do not know since I have not been able to find any scientific articles comparing the results, or effects. Only 'microcurrent' (as far as I could tell single current) as a stimulant for the healing of ligaments. If anyone has any other, more detailed info, please post it.
I was very blonde in science, so maybe I did not understand properly, but as far as I know current is current, only the amperage matters. |

There are various "shapes" of current. PQ stated that when purchasing a microcurrent machine, look for one with a square waveform. But then all that went out the window with the Pico which is second generation current (whatever that is!)
I'm with you, I think current is current too. That's why I'd like to know what you pay for when you purchase something like the CACI. |

Here's another article mentioning the various waveforms:
Variety of waveforms. The type of waveform used in microcurrent varies, depending on the area of treatment. Studies indicate that a modified square waveform is best for muscle-lifting, while a slope waveform is better for collagen-building. Other microcurrent waveforms include square and sawtooth.
This is also interesting:
Clients must be advised to drink additional water before the treatment to allow for proper conductivity of current, and since lymph drainage is activated with microcurrent, clients will feel nauseous if they do not drink a sufficient amount of water after the treatment. Although you can work on any area of the body, do not work on a client for longer than 90 minutes to prevent overloading their system with the stored toxins in their body that will be released. Microcurrent will continue to stimulate ATP levels for 70 hours after treatment. For this reason, it is suggested that you perform the treatment no more than once every three days. Additional treatments will not hurt the client, but are unnecessary. More current is not better and can actually decrease ATP levels because of the overstimulation of cells, so do not tamper with the machine to increase frequency above the manufacturer’s suggested levels. |

i am too very interested in learning the points raised by Keliu.
Havana, the link you posted is very informative indeed.
but is there a consensus conclusion in the scientific field on this topic?
or different manufacturers are just backing up their own products with vested interest? |

I’m not sure but am interested in this too, jessicantique. Here are a few excerpts that add a bit more info:
From the Health and Beauty Therapy: A Practical Approach textbook, page 109--

A micro-current machine has a waveform (whereas traditional galvanic machines do not). The waveform is the “shape” of the current (as can be seen on an oscilloscope -- a special device to visualize and measure electrical current). Most machines produce a selection of waveforms. These are often selected for use according to client’s needs, for example a sharp waveform may be recommended for a client with a severe ageing condition, and a gentle waveform for a younger client with good muscle tone. The waveform is created by interrupting the direct current and controlling the actual build-up, duration and decline of the pulses.
The selection of frequency indicates the number of pulses per second emitted from the machine (the number of waves that pass any fixed point in a second) and are measured in hertz (Hz). The higher the frequency, the shorter the wavelength (the intensity shows the strength of the current and is shown in micro-amps).
Some manufacturers generate pulses as direct current, then reverse each alternate pulse electronically. Some enable the operator to select the options of pulse, frequency, intensity and waveforms, while others pre-set them. |
From Milady’s Aesthetician Series: Aging Skin, page 134 & 135 --

Microcurrent is micro-amerpage stimulation, which is insufficient to activate motor nerves that would cause muscle movement. Microcurrent works with the body’s own electrical impulses to increase cellular reactions that slow down as we age, get injured, have an illness, or experience an increase in stress. Microcurrent assists the body by mimicking the body’s bioelectric currents. The leads to the repairing of tissue and increased cellular metabolism, activity, and exchange.
Microcurrent uses direct electric currents ranging from 10 mA to 500 mA at varied waveforms and frequencies. Some manufacturers include a faradic current, which is an interrupted AC current. Technology is rapidly changing; a new addition to the microcurrent market is the addition of nanotechnology. The theory is that nano current, current in the range of a one-billionth of an ampere, is more readily recognized by the cells; these currents have been shown to even produce amerpage in the pico range, or one-trillionth of an ampere.
Most manufacturers have their own proprietary information about how their machines product currents and waveforms. The different waveforms are square, sine, rectangle, and pulsed. These are standard waveforms recognized within electrical engineering; how a company chooses to modify and market them is the key to selling their machines. Also used are low- and high-frequency currents that also are proprietary to certain manufacturers. |
