EC Electrolysis Equipment and Maintenance 2 — Questions and Answers
Question 1: What is the primary purpose of the rheostat in an electrolysis epilator unit?
- To filter electrical current
- To regulate and control current intensity (Correct answer)
- To convert AC to DC current
- To measure skin resistance
Correct answer: To regulate and control current intensity
The rheostat acts as a variable resistor that allows the electrologist to adjust and control the intensity of current delivered during treatment.
Question 2: Which gauge of probe/needle is considered the finest and would be used for the most delicate hair removal work?
- F2
- F3
- F4
- F5 (Correct answer)
Correct answer: F5
The F5 is the finest gauge probe, used for very fine, vellus hairs in sensitive areas requiring the most delicate treatment.
Question 3: What happens to the electrolysis unit's output if the client's skin becomes increasingly moist during treatment?
- Current intensity automatically increases
- Skin resistance decreases, allowing more current flow (Correct answer)
- The unit shuts down to prevent damage
- Current intensity automatically decreases
Correct answer: Skin resistance decreases, allowing more current flow
Moist skin has lower electrical resistance, which allows more current to flow at the same voltage setting, potentially intensifying the treatment effect.
Question 4: In a blend epilator, what is the role of the galvanic component?
- To produce heat at the needle tip
- To create lye (sodium hydroxide) that destroys the follicle (Correct answer)
- To vibrate the probe at high frequency
- To measure follicle depth electronically
Correct answer: To create lye (sodium hydroxide) that destroys the follicle
The galvanic DC current causes electrolysis of tissue fluids, producing sodium hydroxide (lye) that chemically destroys the follicle's germinating cells.
Question 5: How should the indifferent (inactive) electrode be positioned during galvanic electrolysis?
- Clipped to the electrologist's wrist
- Held firmly in the client's hand or attached to their arm (Correct answer)
- Placed under the client's foot
- Positioned near the treatment area only
Correct answer: Held firmly in the client's hand or attached to their arm
The indifferent electrode must be held firmly by the client or secured to their arm to complete the galvanic circuit and allow proper current flow.
Question 6: What is the correct procedure for disposing of used electrolysis probes/needles?
- Discard in regular waste after capping
- Place immediately in an approved sharps container (Correct answer)
- Sterilize and reuse with different clients
- Wrap in gauze and dispose in biohazard bags
Correct answer: Place immediately in an approved sharps container
Used probes must be immediately disposed of in an approved puncture-resistant sharps container to comply with bloodborne pathogen standards and prevent needlestick injuries.
Question 7: A technician notices the epilator's timer is not accurately measuring treatment seconds. What is the most likely impact on treatment?
- Probe insertion will become more difficult
- Treatment intensity per follicle will be inconsistent (Correct answer)
- The galvanic and RF blend will be disrupted permanently
- The autoclave sterilization cycle will be affected
Correct answer: Treatment intensity per follicle will be inconsistent
An inaccurate timer means the electrologist cannot reliably control how long current is applied per follicle, leading to inconsistent results—over- or under-treatment.
