|
passes through a small part of the body
|
|
|

|
|
|
effects of electric current
|
heating effects, mechanical or magnetic effects, electrochemical effects
|
|
|
electrochemical effects
|
are created when electric current travels through a water base solution (a liquid conductor) in order to produce relaxing or stimulating results
|
|
|
electrotherapy
|
application of special currents that have certain effects on the skin
|
|
|
galvanic current
|
is a direct current of low voltage and high amperage
|
|
|
galvanic current
|
had chemical effects that are caused by passes the current through particular acid or alkaline solutions and/or by the current through body tissues and fluids
|
|
|
cathode
|
negatively charged electrode
|
|
|
anode
|

|
|
|
acid
|
+
|
|
|
alkali
|
-
|
|
|
phoresis
|
the process of forcing an acid or alkali into the skin by applying current to the chemical
|
|
|
anaphoresis
|
uses a negative pole(cathode) or electrode to force negatively charged (alkaline) solution into the skin without breaking the skin
|
|
|
cataphoresis
|
uses a positive pole (anode) or electrode to force positively charged (acidic) solutions into the skin without breaking the skin
|
|
|
anaphoresis
|
the negatively pole of galvanic current is believed to have the following temporary on the area of the body to which it is applied:
1. produces an alkaline reaction which can force alkaline solutions to penetrate the skin 2. increases blood flow by expanding the vessels to aid circulation 3. softens tissue 4. stimulates nerves |
|
|
cataphoresis
|
the positive pole of galvanic current is believed to have temporary effects opposite to those produced by the negative pole, including:
1. produces an acidic reaction, which can force acidic solutions to penetrate the skin 2. slows the blood flow by contracting the vessels to decrease redness or inflammation when applied to simple blemishes on the skin 3. harden tissue, closing pores after facial treatments 4. soothes nerves |
|
|
iontophoresis
|
introduces water treatment products into the skin
|
|
|
desincrustation
|
treatment in which sebum is broken down or black heads are liquefied, as in deep pore cleansing
|
|
|
faradic current
|
is a alternating current, interrupted to produce a mechanical, nonchemical reaction
|
|
|
faradic current
|
stimulates the nerve and muscle tissue
|
|
|
faradic current (benefits)
|
1. improves blood circulation
2. improved muscle tone 3. stimulates hair growth 4. increased glandular activity |
|
|
sinusoidal current
|
an alternating current with a mechanical effect and produces muscle contractions
|
|
|
tesla
|
high frequency current known as violet ray. it's an alternating current
|
|
|
3 methods for using tesla currents
|
