Black.
What does anaphoresis do?
Stimulate and irritate the nerves.
What is NOT a benefit of using Tesla high-frequency current?
Decreases elimination and adsorption.
Who holds the tube electrode with the indirect method of application for high-frequency current?
Client.
What is a characteristic of short wavelengths?
Penetrate less.
What type of light is a combination of all the visible rays of the spectrum?
White.
What type of ultraviolet (UV) rays are known as the burning light?
UVB.
What is NOT a benefit of LED treatments?
Shrink melanomas.
What color LED is used to improve elastin production in the skin?
Red.
What color LED is used to reduce hyperpigmentation?
Green.
Alternating Current (AC)
Rapid and interrupted current, flowing first in one direction and then in the opposite direction.
Electric Current
Flow of electricity along a conductor in a complete circuit.
Anaphoresis
Process of infusing a negative (alkaline) product into the skin.
Anode
Positive electrode.
Live Connection
This supplies current to the circuit.
Light Therapy
Application of light rays to the skin for the treatment of acne, wrinkles, pigmentation, or hair removal.
Conductor
Any material that easily conducts electricity.
Polarity
This indicates the negative or positive pole of an electric current.
Ground Connection
This completes the circuit and carries the current safely away to the ground.
