Chapter 8 Flashcards by Natalie Reinhardt

Alternating current

Abbreviated AC: rapid and interrupted current, flowing first in one direction and then in the opposite direction; produced by mechanical means and changes directions 60 times per second

Fuse

A special device that prevents excessive current from passing through a circuit

Galvanic current

A constant and direct current. Uses a positive and negative pole to produce the chemical reactions and ionic reactions

Green light

A light emitting diode for the use on clients with hyperpigmentation or for detoxifying the skin.

Grounding

The ground connection completes the circuit and carries the current safely away to the ground

Inactive electrode

Opposite pole from the active electrode

Infrared light

Has longer wavelengths, penetrates deeply, has less energy, and produces more heat than visible light. Makes up 60% of natural sunlight

Insulator

Non conductor. Doesn't conduct electricity

Intense pulse light

Light device that uses multiple colors and wavelengths of focused light to treat spider veins, hyperpigmentation, redness, wrinkles, pores, and excessive hair

Invisible light

Light at either end of the visible spectrum of light that is invisible to the naked eye

Iontophoresis

AKA ionization. Process of infusing water-soluble products into the skin with the use of an electric current

Kilowatt

1000 watts. Abbreviated K

Laser

Light Amplification Stimulation Emission of Radiation. Used for hair removal and skin treatments

LED

Light-Emitting Diode. A device used to reduce acne. And improve collagen in skin

Light therapy

The application of light rays to the skin for the treatment of acne, wrinkles, capillaries, pigmentation, or hair removal

Microcurrent

And extremely low level of electricity that mirrors the body's natural electrical impulses

Milliampere

One-thousandth of an amp

Modalities

Currents used in electrical facial and scalp treatments.

Ohm

Abbreviated O. Unit that measures the resistance of electric current

Photo thermostats

Process of light from a laser turning into heat

Plug

Two or three pronged connector at the end of an electrical current

Polarity

Tesla high frequency current

Also know as violet ray. Heat producing current with a high rate of vibration. For scalp and facial treatments

Ultraviolet radiation

Invisible rays that have short wavelengths, least penetrating, produce chemical effect, kills germs

Visible light
