Direct current and Alternating current
DC and AC
the transfer of heat via direct contact
Conduction
the transfer of heat via liquid or gas
Convection
the transfer of heat via vacuum (empty space)
Radiation
Ultraviolet burning
UVB
the light that humans can see on the spectrum
Visible light
the flow of blood through the smallest vessels in the body
Microcirculation
length of time that a current is flowing
pulse
Ultarviolet aging
UVA
short pulses of light and heat break up target molecules
photomechanical
Light-emitting diode
LED
The widening of blood vessels
Vasodilation
Uninterrupted direct current
Galvanic
interrupted direct current
Faradic
direct current with one polarity
pulsed DC
thermal breakdown of the skin
Pyrolysis
a non invasive cosmetic procedure that exfoliates the skin
Microdermabrasion
alternating current with sine waveforms and low frequency
Sinusoidal
prolonged heating of the tissue to cause ablation
Photothermal
photons penetrate the surface; skin color impacts the transmission
transmission
peeling skin or the shedding of dead skin cells from the outermost layer of the skin
Desquamation
can be achieved when two or more effects of electric energy are produced at the same time
Combonation effect
the smallest wavelength and the most energy
Gamma rays
reaction with light and molecules in the body that cause a chemical change or cellular stimulation
Photochemical
Infrared and UV
