Terms in this set (51)
Electrode of an electrotherapy device that is used on the area to be treated
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
Abbreviated A and also known as amp; unit that measures the amount of an electric current (quantity of electrons flowing through a conductor)
Process of infusing an alkaline (negative) product into the tissues from the negative pole toward the positive pole.
Positive electrode; the anode is usually red and is marked with a P or a plus (+) sign.
A light-emitting diode for use on clients with acne.
Process of forcing an acidic (positive) product into deeper tissues using galvanic current from the positive pole toward the negative pole; tightens and calms the skin.
Negative electrode; the cathode is usually black and is marked with a N or a minus () sign.
The colored cells or target in the epidermis or dermis that absorbs the laser beam's thermal energy, causing the desired injury or destruction of the material.
Switch that automatically interupts or shuts off an electric circuit at the first indication of overload.
complete electric 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.
Process used to soften and emulsify sebum and blackheads in the follicles.
Abbreviated DC; constant, even-flowing current that travels in one direction only and is produced by chemical means.
The flow of electricity along a conductor
The movement of particles around an atom that creates pure energy; form of energy that, when in motion, exhibits magnetic, chemical, or thermal effects; a flow of electrons.
Also known as probe; applicator for directing the electric current from an electrotherapy device to the client's skin.
Also known as electromagnetic spectrum of radiation; spectrum ranges from the longest waves to the shortest. made up of all forms of energy whose
The use of electrical devices to treat the skin and for therapeutic benefits.
A special device that prevents excessive current from passing through a circuit.
A constant and direct current (DC); uses a positive and negative pole to produce the chemical reactions (desincrustation) and ionic reactions (iontophoresis).
A light-emitting diode for use on clients with hyperpigmentation or for detoxifying the skin.
The ground connection completes the circuit and carries the current safely away to the ground.
Opposite pole from the active electrode.
Infrared light has longer wavelengths, penetrates more deeply, has less energy, and produces more heat than visible light; makes up 60 percent of natural sunlight.
Also known as nonconductor, substance that does not easily transmit electricity
intense pulse light
Abbreviated IPL; a medical device that uses multiple colors and wavelengths (broad spectrum) of focused light to treat spider veins, hyperpigmentation, rosacea and redness, wrinkles, enlarged hair follicles and pores, and excessive hair
Light at either end of the visible spectrum of light that is invisible to the naked eye.
Also known as ionization; process of infusing water-soluble products into the skin with the use of electric current, such as the use of positive and negative poles of a galvanic machine or a microcurrent device.
Abbreviated K; 1,000 watts.
Acronym for light amplification stimulation emission of radiation; a medical device that uses electromagnetic radiation for hair removal and skin treatments
Acronym for light-emitting diode; a device used to reduce acne, increase skin circulation, and improve the collagen content in the skin.
Also known as phototherapy; the application of light rays to the skin for the treatment of acne. wrinkles, capillaries, pigmentation, or hair removal.
An extremely low level of electricity that mirrors the body's natural electrical impulses.
Abbreviated mA; one-thousandth of an ampere.
Currents used in electrical facial and scalp treatments.
Abbreviated O; unit that measures the resistance of an electric current.
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.
A light-emitting diode for use on clients in the stimulation of circulation and collagen and elastin production.
Tesla high-frequency current
Also known as violet ray; thermal or heat-producing current with a high rate of oscillation or vibration that is commonly used for scalp anf facial treatments.
ultraviolet (UV) radiation
Invisible rays that have short wavelengths, are the least penetrating rays, produce chemical effects, and kill germs.
The primary source of light used in facial and scalp treatments.
Abbreviated V and also known as voltage; unit that measures the pressure or force that pushes the flow of electrons forward through a conductor.
Abbreviated W; measurement of how much electric energy is being used in one second.
Distance between two successive peaks of electromagnetic waves
Referred to as combination light because it is a combination of all the visible rays of the spectrum.
A light-emitting diode which aids in reducing inflammation and swelling
