is a form of energy that, when in motion exhibits magnetic, chemical, or thermal effects
Any substance that is easily transmits electricity. Any metal can be this.
Another name for non-conductor.
A substance that does not easily transmit electricity. Rubber is this.
is the path of an electric current from the generating source through conductors and back to its original source.
Direct Current (DC)
is constant, even flowing current that travels in on direction only. Example would be flashlight, cellular telephones and cordless electric drills produced by batteries.
Alternating Current (AC)
is a rapid and interrupted current, flowing first i one direction and then the opposite direction. Hair dryers and curling irons that plug into the wall outlet use this produced by generators.
is an apparatus that changes alternating current to direct current.
is the unit that measures the pressure or force that pushes the flow of electrons forward through a conductor, much like the waters pressure that pushes the water molecules through the hose.
Another name for Volt
is the unit that measures the strength of an electric current (the number of electrons flowing through a wire).
Another name for Amp.
is one thousandth of an ampere.
is a unit that measures teh resistance of an electric current.
is a measurement of how much electric energy is being used in one second.
is 1000 watts.
is a special device that prevents excess current from passing through a circuit. It is designed to blow out or melt when the wire becomes too hot from overloading the circuit with too much current - Too many appliances or faulty equipment.
is a switch that automatically interrupts or shuts off an electric circuit at the first indication of overload. Circuit breakers have replaced fuses in modern electric circuits.
is another way of promoting electrical safety. All electrical appliances must have at lease two electrical connections.
What does UL stand for?
Electrical facial treatments are commonly referred to as:
Electrical treatments are often called:
Indicates the negative or positive pole of an electric current.
Positive polls are usually red and called:
Negative polls are usually black and called:
Galvanic/Faradic/Sinusoidal/Telsa High Frequency
Name the four modalities:
Unblock clogged pores, is the most commonly used modality and drive solutions deeper into the epidermis. It is a constant DC, having a positive and negative pole, and produces chemical changes when it passe through the tissues and flids of the body.
is the electrode used on the area to be treated.
is the positive pole from the active electrode.
is a term for the process of introducing water-soluble products into the skin with the used of electric current, such as positive and negative poles of a galvanic machine.
Forces acidic substances into deeper tissues by using galvanic current from the positive toward the negative pole.
is the process of forcing alkaline liquid into the tissue from the negative toward the positive pole.
is a process which uses the negative pole to soften and emulsify grease deposits (oil) and blackheads in the hair follicles.
is an alternating and interrupted current that produces mechanical reaction without a chemical effect.
is similar to faradic current and is also used during scalp and facial manipulations.
is an extremely low level of electricity that mirror's the body's own natural electrical impulses. Through electrical stimulation, works by mimicking the way that the brain relays messages to the muscles. These treatments have also been shown to benefit stroke and paralysis patients.
Telsa High Frequency Current
is a thermal or heat producing current with a high rate of oscillation or vibration. It is commonly called violet ray and is used for both scalp and facial treatments.
Direct Surface Application
(High Frequency) The ethetician holds the hand-piece. Also, must hold the your finger on the glass electrode to prevent sparking.
The client holds the tube electrode (with the metal coil inside). while the esthetician massages the face with her hands.
The three light waves estheticians work with that produce germicidal reaction.
is electromagnetic radiation that that we can see.
Also called radiant energy, carries or radiates energy through space on waves.
The distance between two successive peaks is called:
Also forms of electromagnetic radiation, but they are invisible because their wavelengths are beyond the visible spectrum of light. The waves make up 65% of natural sunlight.
Another name for Phototherapy.
Light used for dry skin types.
Light used for combination skin types.
Light used for oily skin types.
Process by which light from a laser is turned into heat.
