Q

What type of current uses alternating current that can be adjusted to different voltages to produce heat? Known as the “violet ray”. Does not produce muscle contractions. Can result in relations or stimulation depending on method of application.

A

High-frequency current, Tesla

17
Q

What are the 2 methods for using High-Frequency current?

A
  1. Direct Application- used for mild acne and/or blackheads facial treatment, and scalp treatment
  2. Indirect Application- used for dry skin facial treatment, and dry scalp
  3. General Electrification
18
Q

Microcurrent treatments should never exceed what time?

A

30 min

19
Q

Limit galvanic treatment to what time?

A

4-7

20
Q

Electrodes should never touch each other. True or False?

A

True

21
Q

Heat always moves from a hotter body to a cooler body and can be transferred by:

A

Conduction- direct contact
Convection- liquid or gas
Radiation- through a vacuum

22
Q

The chemical breakdown of the skin due to extreme heat is called?

A

Pyrolysis

23
Q

The production of benefical effects such as reducing acnes through treatments using light rays or waves is called?

A

Light therapy

24
Q

Laser stands for:

A

Light Amplification Simulation Emmision of Radiation

25
Q

LED (light-emitting diode) devices are primarily used to:
blue light:
red light:
yellow light:
green light:

A

blue light: reduce acne
red light: increase circulation
yellow light: reduce imflammation
green light: reduce hyperpigmentation

26
Q

Intense Pulse Light (IPL) devices are used to treat:

A

spider veins, wrinkles, hyerpigmentation, excessive hair, rosacea

27
Q

The portion of the electromagnetic spectrum that humans can see is called? Waves hit an ogject and are absorbed or reflected.

A

Visible Light

28
Q

Two types of light that is not visible to the human eye?

A

Infrared and utlraviolet

29
Q

Which type of invisible light produces heat. Benefits include increased circulation, increased skin gland secretions, relaxation of muscles, stimulation of cell and tissue activity

A

Infrared light

30
Q

Which type of invisible light can be more damaging. Some positive effects include: small doses can tan the skin, may help produce vitamin D, kills bacteria that causes skin infections, promotes healing and is used in treatment of ance. Negative effects include sunburned skin, damaged eys and hair, possible skin cancer

A

Ultraviolet Light (UV), also called actinic light

31
