Terms in this set (57)
the movement of particles around an atom that creates pure energy. form of energy that exhibits magnetic, chemical, or thermal effects when in motion.
the flow of electricity along a conductor.
any material that conducts electricity meaning electricity will pass through the material easily.
material that does not transmit electricity. (insulator) such as rubber, silk, wood, glass, cement.
complete electric circuit
path of negative and positive electric currents moving from the generating source through the conductors and back to the generating source.
DC, a constant, even-flowing current that travels in one direction and is produced by chemical means. (flashlights, mobile phone, cordless hairstyling tools use the direct current produced by batteries.)
an apparatus that changes direct current to an alternating current. (DC to AC)
AC, a rapid and interrupted current, flowing first in one direction and then in the opposite direction. produced by mechanical means and changes directions 60x/second.
an apparatus that changes alternating current to direct current. (AC to DC)
unit that measures the PRESSURE or force that pushes electric current forward through a conductor. higher voltage indicated more power. (V)
unit that measures the STRENGTH of an electric current. (A)
1/1,000 of an ampere. (mA)
unit that measures the RESISTANCE of an electric current. current will not flow through a conductor unless the force (volts) is stronger than the resistance (ohms) (O)
unit that measures how much electric energy is being used in one second. 40 watt bulb=40 watts of energy/second.
prevents excessive current from passing through a circuit. found in older buildings.
a switch that automatically interrupts or shuts off an electric circuit at the first indication of an overload. they have replaced fuses in modern electric circuits.
completes an electric circuit and carries the current safely away. the prongs in electrical connections must have two .
currents used in electrical facial and scalp treatments. (cosmo modalities: galvanic current, micro current, tesla high-frequency current.
also known as a probe, it is an applicator for directing electric current from and electrotherapy device to the clients skin. Made of carbon, glass, metal.
the negative or positive pole of an electric current.
positive electrode. red. marked with a P or + sign.
negative electrode. black. marked with N or - sign
a constant and direct current, having positive and negative pole, that produces chemical changes when it passes through the tissues and fluids of the body.
the electrode used in the area to be treated.
the opposite pole from the active electrode.
the process of infusing water-soluble products into the skin with the use of electric current, such as the use of positive/negative poles of a galvanic machine.
infuses an acidic (positive) product into deeper tissues using galvanic current from the positive pole toward the negative pole.
infuses an alkaline (negative) product into the tissues from the negative pole toward the positive pole.
a form of anaphoresis and is a process used to soften and emulsify grease deposits (oil) and blackheads in the car follicles.
an extremely low level of electricity that mirrors the body's natural electrical impulses. can be used for iontophoresis or to treat acne.
tesla high-frequency current
also known as violet ray, is a thermal or heat-producing current with a high rate of oscillation or vibration that is common used for scalp and facial treatments.
name given to all forms of energy that exist.
the distance between two successive peaks of electromagnetic waves. energy moves through space in waves.
the measurement of the distance between two wavelengths
low frequency waveform, deeper penetration, less energy
high frequency waveform, less penetration, more energy
visible spectrum of light
part of the electromagnetic spectrum that can be seen. 35% of natural light.
the light at either end of the visible spectrum of light that is invisible to the naked eye. 65%
invisible light that has a short wavelength so less penetrating but higher energy. causes chemical reactions to happen more quickly than with visible light. 60%
light that has longer wavelengths, penetrates more deeply, has less energy, and produces more heat than visible light. used during conditioning treatments and to process hair color.
substances that speed up chemical reactions.
the application of light rays to the skin for treatment of wrinkles, capillaries, pigmentation or hair removal.
light amplification stimulation emission of radiation. electromagnetic radiation for hair removal and skin treatments.
process that turns light from the laser into heat.
light emitting diode. a medical device to reduce acne, increase skin circulation, and improve collagen content in skin.
works by releasing light onto the skin to stimulate a specific responses at precise depths of the skin tissue.
a color component within the skin such as blood or melanin.
reduces acne, bacteria
increases circulation, collagen and elastin production, stimulates wound healing
reduces swelling and inflammation, improves lymphatic flow, detoxifies and increases circulation
reduces hyper pigmentation, redness, calms and soothes.
intense pulse light
medical device that uses multiple colors and wavelengths (broad spectrum) of focused light to treat spider veins, hyper pigmentation, rosacea and redness, wrinkles, enlarged pores, excessive hair.
visible spectrum of light
part of the electromagnetic spectrum that can be seen.
abbreviated AC, a rapid and interrupted current, flowing first in one direction and then in the opposite direction. produced by mechanical means and changes directions 60x/second.
light with longest wavelength of UV light spectrum, penetrates directly into the dermis of skin, damaging collagen and elastin.
often used in tanning beds.
light that is most associated with sunburns.
light that is blocked by ozone layer .
