Transcript Galvanic current

Galvanic current
Effects, treatments, facts
Galvanic is applied at the end
of the facial

Description


Low voltage ( 60-80 volts )
Low intensity current with constant polarity during the
application time

Example
– Flow of water thru a canal that has constant width

Effects

Classified in

Polar
– Occur in the areas on the skin that are in direct contact with the
electrodes

Interpolar
– Occur in the area that the current flows thru

Effects
Interpolar
Increases in superficial blood circulation
Temperature increase
Stimulates cell metabolism due to iron movement between cells

Intro to Treatments

Ionization



Process to help in the absorption of ionizable cosmetic
products
There are as many treatments as ionizable products in the
market
Disincrustation

Deep cleaning of sebaceous secretions
Bleaching of pigmentation spots
 Galvanization


Application to just get the beneficial effects of the current
Facts
A:
 Apply to all treatments
 Set a circuit to let the current flow
 It is necessary to work with a minimum of two cords
(+ & - )



Always work in pairs
To make it easier, an “active” and a “passive” or
“grounding” electrode may be considered
Facts


Active electrode has the necessary polarity ( +,- ) to
do the treatment and is associated to the red color
cord
The grounding is mainly used to set the circuit and
let the current flow



For this purpose, conductive gel, tap water, or physiological
solution are used
The grounding is associated to the black color cord
There are several ways to set the circuit


The red cord is connected into the red machine outlet
The black cord is connected into the black outlet
Facts
B:
 Intensity – there is a maximum that
depends on the contact surface of the
active electrode regardless of the
client’s sensation
 The intensity must not be set higher
than 0.05 mA per cm2 of electrode
surface
 Even if the client has no sensation,
higher intensity must not be used

Facts

This maximum must not be over passed
Microgalvanic


Roller electrode - .99 mA

Point electrode - .20 mA

Ball electrode .20 mA


Big pad (body) – 4.00 mA

Small pad – 2.00 mA

Product, polarity, time
Each treatment requires a different type of product, polarity (+,-) and duration time,
according to the following chart:

*1 Ionizable product is a cosmetic substance that
has been especially manufactured to be used with
galvanic current and ha, therefore, an ion
composition
If the product is not ionizable, a galvanization will
be done composition
If the product is not ionizable, a galvanization will
be done instead of a ionization
The polarity of the product ( +,- ) and the
treatment advised duration time is indicated by the
product manufacturer.
Ionizable products are normally water soluble
*2Disincrustation lotion is a solution
designed to turn the sebum acids into a
soap-like substance
 For instance:

A solution of 10 % baking soda and
distilled water
 A solution of 5 % sodium chloride (ClNa)
and distilled water

*3 The orange acidity is appropriate for
this treatment.
 It is not advisable to use lemon
 *4 a conductive product is a substance
that is a good electrical conductor

*5 the skin condition and the particular
manufacture indications are to be taken
into consideration
 It is possible and advisable to decrease
the treatment intensity and
proportionally increase the duration
time
 A intensity lower than that previously
stated in point of intensity of + & -.
