Question 1: Electrochemical EFfect

Answer:

created when an electric current travels through a water-based solution and onto the body. Utilized during Galvanic treatments.

Question 2: Electrons

Answer:

tiny, negatively charged particles which make up electric current.

Question 3: Electricity

Answer:

a form of energy which produces light, heat, and magnetic and chemical changes.

Question 4: Anode

Answer:

a positively charged electrode; usually red in color and displayed a large "P" or a positive sign (+).

Question 5: Prism

Answer:

a three-sided glass object which can split wavelengths from visible light into their individual colors.

Question 6: Battery

Answer:

a device which converts electrochemical energy into electrical energy when a load is switched on.Electrons collect on the negative terminal and travel towards the positive one, through the chemical medium, and into the equipment.

Question 7: Open Circuit

Answer:

when a closed path is broken. Stops the flow of electricity to a load.

Question 8: Direct High Frequency

Answer:

a High Frequency treatment that involves the esthetician placing the electrode on or a short distance away from the client's face. This produces an ozone gas that has germicidal effects while also eliminating excess sebum. 5 minutes.

Question 9: Radiation

Answer:

the transfer of heat energy through empty air space.

Question 10: Argon

Answer:

a gas which produces a rich purple color during High Frequency treatments. Used on acne-type lesions.

Question 11: Ohm

Answer:

a unit of electric resistance.

Question 12: Neon

Answer:

a gas which produces a bright orange color during High Frequency treatments. Used on normal to oily skin to create warmth in a localized area for improved product penetration or to increase circulation.

Question 13: Cataphoresis

Answer:

a type of phoresis which allows an acidic solution to enter the skin when assisted by Galvanic Current and the positive pole of an electrode.

Question 14: Direct Faradic

Answer:

a method of application for Faradic Current in which both electrodes are placed on the client's skin without ever touching. Stimulates motor nerves.

Question 15: Watt

Answer:

a measure of electrical energy being used.

Question 16: Underwriter's Laboratory

Answer:

UL rating; means the appliance has been certified to operate safely under specified conditions.

Question 17: Overload

Answer:

describes when a line carries more amps than it is designed to carry. Without fail-safes, lines can burn and catch fire.

Question 18: Lucas Spray

Answer:

the electric pulverizer spray; invented by Dr. Lucas Championniere. A unique atomizer that allows for the application of herbs, extracts, or astringents to be applied in a very fine mist. Refreshes, soothes, and tones the skin.

Question 19: Rectifier

Answer:

an instrument which changes Alternating Current to Direct Current.

Question 20: UVC

Answer:

UV rays that are beyond the ozone layer and have little effect on exposure which the skin receives. The shortest in length of UV rays. 200nm to 280 nm.

Question 21: Cathode

Answer:

a negatively charged electrode; usually black in color or displays a large "N" or negative sign (-).

Question 22: Electromagnetic Spectrum

Answer:

the range of wavelengths that can be produced by radiant energy.

Question 23: Amp Rating

Answer:

indicates the number of electrons flowing through a particular line.

Question 24: Magnifying Lamp

Answer:

a loupe; a device which provides light and magnification. Allows esthetician to examine the surface of the skin more closely.

Question 25: Electrotherapy

Answer:

the application of electrical energy during skin treatments.

Question 26: Paraffin Heating Unit

Answer:

electric containers that melt blocks of paraffin wax for use in face, hand, foot, and body treatments.Paraffin is both moisturizing and relaxing; effective treatment for dry skin. Increases rate of product penetration and warms skin.

Question 27: Fuse

Answer:

a safety device that prevents electrical wires from overheating. Contains fine wire which melts when too much current is present.
