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.
Direct current (DC)
Constant, even-flowing current that travels in one direction only.
Microcurrent.
Extremely low level of electricity that mirrors the body’s own natural electrical impulses.
Cathode.
Negative electrode.
Insulator.
Substance that does not conduct electricity.
Electrotherapy.
Electrical facial treatments.
Cataphoresis.
Process of infusing a positive (acid) product into the skin.
