inactive electrode

Question 13

This is the process of infusing water-soluble products into the skin with the use of electric current

Answer 13

iontophoresis

Question 14

Answer 14

cataphoresis

Question 15

A form of iontophoresis in which galvanic current is used to infuse alkaline products into the skin. Uses the negative pole

Answer 15

anaphoresis

Question 16

A form of anaphoresis that softens and emulsifies grease deposits and blackheads in hair follicles

Answer 16

desincrustation

Question 17

An extremely low level of electricity that mirrors the body’s natural electrical impulses. Can be used for iontophoresis, firming, toning, and soothing skin

Answer 17

microcurrent

Question 18

This type of electrotherapy improves blood and lymph circulation, increases muscle tone, restores elasticity, and increases metabolism

Answer 18

microcurrent

Question 19

Also known as a violet ray, this is a thermal or heat-producing current with a high rare of oscillation or vibration that is commonly used for scalp and facial treatments

Answer 19

Tesla high-frequency current

Question 20

This type of electrotherapy stimulates blood circulate, increases elimination and absorption, improves germicidal action, and relieves skin congestion

Answer 20

Tesla high-frequency current

Question 21

Name some contraindications for the Tesla high-frequency current

Answer 21

pregnancy, epilepsy, asthma, high blood pressure, pacemaker, metal implants

Question 22

Name some of the effects of cataphoresis

Answer 22

produces acidic reactions, closes pores, soothes nerves, decreases blood supply, contracts blood vessels, hardens and firms tissues

Question 23

Name some of the effects of anaphoresis

Answer 23

produces alkaline reactions, opens pores, stimulates and irritates nerve, increases blood supply, expands blood vessels, softens tissues
