CPE CPE Equipment & Technology 1 — Questions and Answers
Question 1: What is the function of the epilator in electrolysis?
- It generates and delivers the electrical current used to destroy the hair follicle (Correct answer)
- It sterilizes probes before each insertion
- It magnifies the treatment area for better visibility
- It cools the skin to reduce discomfort during treatment
Correct answer: It generates and delivers the electrical current used to destroy the hair follicle
The epilator is the electrical device that produces and controls the current (galvanic, thermolysis, or blend) delivered through the probe to the follicle.
Question 2: Which type of electrolysis current uses high-frequency alternating current to generate heat within the follicle?
- Thermolysis (shortwave/RF) (Correct answer)
- Galvanic (DC)
- Blend (combined)
- Infrared
Correct answer: Thermolysis (shortwave/RF)
Thermolysis uses high-frequency alternating current to create oscillating heat within the follicle tissue, destroying the dermal papilla.
Question 3: What role does the indifferent electrode (body return electrode) play in galvanic electrolysis?
- It completes the galvanic circuit by providing the return path for direct current through the client's body (Correct answer)
- It delivers current directly to each hair follicle
- It measures skin moisture levels during treatment
- It acts as a ground to prevent electrical shock to the practitioner
Correct answer: It completes the galvanic circuit by providing the return path for direct current through the client's body
The indifferent electrode is held by or attached to the client and completes the DC circuit, allowing galvanic current to flow through the tissue.
Question 4: Which probe type is considered disposable and is required for single-client use in most U.S. states?
- Single-use sterile disposable probe (Correct answer)
- Reusable glass probe
- Gold-plated multi-client probe
- Autoclavable stainless steel needle used across multiple clients
Correct answer: Single-use sterile disposable probe
Single-use sterile disposable probes are required in most states to prevent cross-contamination and infection between clients.
Question 5: What does the intensity (current level) setting on an epilator control?
- The amount of electrical energy delivered to the follicle during treatment (Correct answer)
- The length of the treatment session
- The temperature of the treatment room
- The number of hairs removed per minute automatically
Correct answer: The amount of electrical energy delivered to the follicle during treatment
The intensity setting adjusts how much electrical current is applied, which directly affects the effectiveness of follicle destruction and client comfort.
Question 6: What is the purpose of the timing control on a thermolysis epilator?
- It regulates the duration of current application per follicle insertion (Correct answer)
- It schedules automatic appointment reminders
- It controls the brightness of the treatment lamp
- It sets a timer for total session length
Correct answer: It regulates the duration of current application per follicle insertion
The timing control determines how many milliseconds or seconds of current are delivered per probe insertion, affecting treatment efficacy and tissue response.
