CPE Electricity & Modalities in Electrolysis 1 — Questions and Answers
Question 1: What type of electrical current is used in galvanic electrolysis?
- Alternating current (AC)
- Direct current (DC) (Correct answer)
- Pulsed high-frequency current
- Radio-frequency current
Correct answer: Direct current (DC)
Galvanic electrolysis uses direct current (DC), which flows in one direction and causes an electrochemical reaction that produces sodium hydroxide to destroy the hair follicle.
Question 2: Which chemical byproduct of galvanic electrolysis is responsible for destroying the hair follicle?
- Hydrochloric acid
- Hydrogen peroxide
- Sodium hydroxide (lye) (Correct answer)
- Sodium chloride (salt)
Correct answer: Sodium hydroxide (lye)
Galvanic direct current causes electrolysis of tissue fluids, producing sodium hydroxide (lye) at the negative pole, which chemically destroys the germinal cells of the hair follicle.
Question 3: Thermolysis destroys the hair follicle using which mechanism?
- Chemical reaction producing sodium hydroxide
- Magnetic fields disrupting the hair papilla
- Heat generated by high-frequency alternating current (Correct answer)
- Pulsed direct current coagulating tissue proteins
Correct answer: Heat generated by high-frequency alternating current
Thermolysis uses high-frequency alternating current (radio frequency) that causes water molecules in the follicle to rapidly oscillate, generating heat that thermally destroys the germinal cells.
Question 4: The blend method of electrolysis simultaneously combines which two modalities?
- Laser and galvanic current
- Pulsed light and thermolysis
- Galvanic current and thermolysis (Correct answer)
- Galvanic current and pulsed RF
Correct answer: Galvanic current and thermolysis
The blend method combines galvanic direct current and thermolysis high-frequency alternating current simultaneously, destroying the follicle both chemically and thermally.
Question 5: In electrolysis, the intensity of electrical current is measured in which unit?
- Volts (V)
- Ohms (Ω)
- Milliamperes (mA) (Correct answer)
- Watts (W)
Correct answer: Milliamperes (mA)
Milliamperes (mA) measure the intensity (amount) of electrical current delivered during electrolysis treatments, allowing the electrologist to control the strength of treatment.
Question 6: In galvanic electrolysis, which electrode is the cathode (negative pole) where lye is produced?
- The return electrode held by the client
- The treatment probe inserted into the follicle (Correct answer)
- The ground wire attached to the machine
- The metal footrest the client stands on
Correct answer: The treatment probe inserted into the follicle
The treatment probe inserted into the follicle is the cathode (negative pole) in galvanic electrolysis, and sodium hydroxide forms at this site to chemically destroy the follicle.
Question 7: What frequency range is used in thermolysis electrolysis equipment?
- 50–60 Hz (utility frequency)
- 1,000–5,000 Hz (audio frequency)
- Around 13.56 MHz (radio frequency) (Correct answer)
- 1–10 GHz (microwave frequency)
Correct answer: Around 13.56 MHz (radio frequency)
Thermolysis epilators typically operate around 13.56 MHz, which is in the radio frequency (RF) range and is sufficient to cause rapid oscillation of water molecules and generate tissue-destructive heat.
