Milady's Esthetics Chapter 7 Electricity

Basic of Electricity
active electrode
Electrode used on the area to be treated.
alternating current (AC)
Rapid and interrupted current, flowing first in one direction and then in the opposite direction.
amp (A)
Process of forcing liquids into the tissues from the negative toward the positive pole.
Positive electrode
blue light
Negative electrode
circuit breaker
complete circuit
The path of an electric current from the generating source through conductors and back to its original source.
any substance, material, or medium that easily transmits electricity.
apparatus that changes direct current to alternating current
direct current (DC)
electric current
a flow of electricity along a conductor
form of energy that when in motion, exhibits magnetic, chemical, or thermal effects; a flow of elctrons.
applicator for directing the electric current from machine to clients skin
electromagnetic radiation
energy in the form of electromagnetic waves,also called radiant energy because it carries, or radiates, energy though space on waves.
The use of electrical devices for therapeutic benefits.
faradic current
An alternating & interrupted current that produces mechanical reaction without a chemical effect
special device that prevents excessive current from passing through a circuit
galvanic current
constant and direct current, having a positive and negative pole, uses a positive & negative pole to produce the chemical changes of desincrustation, an iontophoresis.
inactive electrode
Opposite pole from the active electrode.
infared rays
insulator (nonconductor)
A substance that does not easily transmit electricity.
iontophoresis (ionization)
process of introducing water-soluble products into the skin by using electric current such as that from the positive and negative poles of a galvanic machine
kilowatt (K)
1,000 watts
an acronym for light amplification by stimulated emission of radiation; a medical device used for hair removal and skin treatments.
light therapy
the application of light rays to the skin for the treatment of wrinkles, capillaries, pigmentation, or hair removal.
a device that mimics the body's natural electrical energy to reeducate and tone facial muscles; improves circulation and increases collagen and elastin production.
one-thousandth of an ampere.
currents used in electrical facial and scalp treatments
ohm (O)
the unit ofelectrical resistance in an electric current
a form of treatment for various skin conditions using artificial light wavelengths from the ultraviolet (blue light) part of the skin's spectrum.
process by which light from a laser is turned into heat.
2-3 prong connector at the end of an electrical cord that connects an apparatus to an electrical outlet.
negative or positive pole of an electric current.
apparatus that changes alternating current to direct current
red light
Therapeutic light used on dry skin in combination with oils and creams; penetrates the deepest and produces the most heat.
sinusoidal current
alternating current similar to faradic current; produces mechanical contractions and is used during scalp and facial manipulations.
tesla high-frequency current
Thermal or heat-producing current with a high rate of oscillation or vibration; also called violet ray.
ultraviolet (UV) rays
visible light
the prinmary source of light used in a facial and scalp treaments
volt (V)
unit that measures the pressuce or force that pushes the flow of electrons forward through a conductor.
watt (W)
measurement of how much electric energy is being used in one second.
distance between two successive peaks of electromagnetic waves
white light
referred to as combination light because it is a combination of all the visible rays of the spectrum.
