Miladys Esthetics Ch 7 Basics 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)
Unit that measures the amount of an electric current (quantity of electrons flowing through a conductor).
Process of forcing liquids into the tissues from the negative toward the positive pole.
Positive electrode.
Blue Light
Therapeutic light that should be used only on oily skin that is bare; contains few heat rays, is the least penetrating, and has some germicidal and chemical benefits.
Process of forcing acidic substances into deeper tissues using galvanic current from the positive toward the negative pole.
Negative electrode.
Circuit breaker
Switch that automatically interrupts or shuts off an electric circuit at the first indication of overload.
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.
Galvanic current is used to create an alkaline chemical reaction that emulsifies sebum and debris.
Direct Current(DC)
Constant, even-flowing current that travels in one direction only.
Electric Current
Flow of electricity along a conductor,.
Form of energy that when in motion, exhibits magnetic, chemical or thermal effect; a flow of electrons.
Applicator for directing the electric current from the machine to the client's skin.
Electromagnetic radiation
Energy in the form of electromagnetic waves; also called radiant energy because it carries, or radiates, energy through space on waves.
The use of electrical devices for therapeutic benefits.
Faradic current
Alternating and interrupted current that produces a mechanical reaction without a chemical effect.
Special device that prevents excessive current from passing though a circuit.
Galvanic Current
A constant and direct current (DC); used a positive and negative pole to produce the chemical changes of desincrustation, an iontophoresis.
Inactive electrode
opposite pole from the active electrode.
Infrared Rays
Invisible rays that have longer wavelengths, penetrate deeper, and produce more heat than visible light does.
Insulator (nonconductor)
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)
1000 watts
Acronym for Light Amplification Stimulation 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 acne, 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)
Unit that measures the resistance of an electric current.
(Light Therapy), this is a form of treatment used for various skin conditions using artificial light wavelengths from the ultraviolet (blue light) part of the sun's spectrum.
Process by which light from a laser is turned into heat.
Two- or three-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 Rays
Ultraviolet Rays (UV)
invisible rays that have short wavelengths, are the least penetrating rays, produce chemical effects, and kill germs; also called cold rays or actinic rays.
Visible Light
The primary source of light used in facial and scalp treatments.
Volt (V)
unit that measures the pressure 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.
