Alternating current (ac)

Rapid and interior current, flowing first in one direction then the opposite direction amp a unit measures the strength of an electric current

1

Amp (ampere)

Standard unit for measuring the strength of electrical current or the rate of flow of change in a conductor. Also called an amp

2

Anaphoresis

Process of forcing substances into tissue using galvanic current from the negative towards the positive pole

3

Anode

Positive Electrode

4

Cataphoresis

Process of forcing substances into tissue using galvanic current from the positive towards the negative pole

5

Cathode

Negative electrode

6

Circuit breaker

Switch that automatically interrupts or shuts off an electric circuit at the first sign of overload

7

Complete circuit

the path of an electronic current from the generating source through the conductor and back to it original source

8

Conductor

Any substance, medium, or material that conducts electricity

9

Converter

An apparatus that changes direct current to alternating current

10

Desincrustation

Process used to soften and emulsify oil and blackheads in the hair follicles

11

Direct current (DC)

Constant current that travels in one direction only and produces a chemical reaction

12

Electric current

The flow of electricity along a conductor

13

Electrode

An applicator used to electric current from a machine to the skin

14

Electrotherapy

Electronic scalp and facial treatments

15

Faradic current

Alternating current that produces a mechanical reaction without chemical effects

16

Fuse

Device that prevents excessive current from passing through a circuit

17

Galvanic current

Constant and direct current, having a positive and negative pole , that produces chemical changes in tissues and body fluids

18

Ground fault circuit interrupter

A device that senses imbalances in an electric current

19

Infrared rays

Invisible rays with long wavelengths and deep penetration; produce the most heat of any therapeutic light

20

Insulator

Substance that does not easily transfer electricity

21

Iontophoresis

Process of introducing water soluble products into the skin through the use of electric current

22

Modalities

Current used in electric facial and scalp treatments

23

Ohm (O)

The unit of electrical resistance in an electric current

24

Polarity

Negative or positive pole of an electric current

25

Rectifier

Apparatus that changes alternating current to direct current

26

Rheostat

An adjustable resistor used for controlling current in a circuit

27

Sinusoidal current

Alternating current used in scalp and facial manipulations that produce mechanical contractions

28

Telsa high-frequency current

Thermal or heat-producing current with a high oscillation rate ; also known as the violent ray.

29

Ultraviolet light

Invisible rays, with short wavelength and minimal skin penetration, that produces chemical effects and kill germs ; also called actinic or cold rays.
