(DC) constant current in which electrons move at an even rate and flow in 1 direction
found on the back of an appliance, certifies that appliance has been rated to work safely under written conditions
indicates the amount of current flowing through the equipment and regulates the amount with a knob or dial
occurs when too many devices are operated on the same circuit at one time. (operation fails)
carefully insulated location where the electric current enters a building from a generator or power plant
a safety device that prevents electrical wires from overheating. wire inside melts when overload occurs
safety device that breaks the flow of current when an overload occurs. 2 pieces of metal separate when overloaded
3 wire system, round prong is the grounding prong- connects directly to the ground below building
human contact with an electrical current; can be anywhere from mild shock-electrocution
passes through a small part of the body, cause burns and muscle contraction. may be severe
(electrocution) passes through the nervous system, causes the heart to stop, breathing to cease and muscle to convulse
ground fault circuit interruptor; senses current leakage in an electrical circuit, will interrupt power if there is contact with H20
(ionization) constant direct current, low voltage, high amperage. Produces an electrochemical effect.
negative or positive charged poles that attract or repel particles in treatment solutions
Tesla current, alternating current that can be adjusted to different voltages to produce heat.
Orange ray (High Frequency)-used on normal to oily skin to create warmth for product penetration and increase circulation
spark gap, lifting the electrode from the skin to create a more powerful ozone *can cause damage
Direct High Frequency
holds the electrode directly on the face, produces ozone to create germicidal effect
Indirect High Frequency
client holds electrode and esthetician gently massages the face. (Viennese Massage)
an alternating current that is interrupted to produce a mechanical, non-chemical reaction, passive form of exercise
esthetician places both electrodes on the client's skin, passes both electrodes over skin, NEVER touching electrodes together.
esthetician wears a wrist band electrode and client holds second electrode, massage focused mainly on motor points
alternating current that produces a mechanical effect, penetrates deeper than faradic. Used on prematurely aging skin
heat energy is transferred by radiation, electrons move in wavelike patterns
infrared rays (IR)
slightly longer wavelength than visible rays, produce heat, penetrate all layers of the skin, affecting muscle, bone, nerves and joints
ultraviolet rays (UV)
slightly shorter wavelength than visible rays, produce - and + effects, healing, Vit D, germicidal, aging, cancer
creates a vacuum on the skin to aid in deeper pore cleansing, by drawing dirt, sebum and impurites out
supplies warm vapor to client's skin, aids in cleansing, exfoliating, stimulates sebum production
eleaborate magnifying mirror/light that allows client and esthetician to see what is happening under skin. uses a black light
