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.
Unit that measures the amount of an electric current (quantity of electrons flowing through a conductor).
Process of forcing liquidss into the tissues from the negative toward the positive pole.
Therpeutic light that should only be used on bare oily skin; contains few heat rays, is the least penetrating, and has some germicidal and chemical benefits.
Any substances having the power to increase the velocity (speed) of a chemical reaction.
Process of forcing acidic substances into deeper tissues using galvanic current from the positive toward the negative pole.
Switch that automatically interrupts or shuts off an electric circuit at the first indication of overload.
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)
Constant, even-flowing current that travels in one direction only.
Process used to soften and emulsify grease deposits (oil) and blackheads in the hair follicle.
Flow of electricity along a conductor.
Form of energy that, when in motion, exhibits magnetic, chemical, or thermal effects; a lflow of electrons.
Applicator for directing the electric current from machine to client's skin.
Also called radiant energy because it carries, or radiates, energy through space on waves.
Special device that prevents excessive current from passing through a circuit.
Constant and direct current (DC), having a positive and negative pole and producing chemical changes when it passes through the tissues and fluids of the body.
Opposite pole from the active electrode.
Invisible rays that have longer wavelengths, penetrate deeper, and produce more heat than visible light.
insulator or nonconductor
Substance that does not easily transmit electricity.
Process of introducing water-soluble products into the skin with the use of electric current, such as the us of the positive and negative poles of a galvanic machine.
One-thousandth of an ampere.
Currents used in electrical facial and scalp treatments.
Unit that measures the resistance of an electric current.
Negative or positive pole of an electric current.
Apparatus that converts alternating current to direct current.
Therapeutic light used on dry skin in combination with oils and creams; penetrates the deepest and produces the most heat.
Tesla high-frequency current
Thermal or heat-producing current with a high rate of oscillation or vibration; aslo called violet ray.
