ELECTROLYSIS AND LASER STATE
BOARD COMPREHENSIVE EXAM
ELECTROLYSIS IBEC & LASER STATE
BOARD FINAL EXAM 2026/2027
1. In Galvanic electrolysis, the chemical reaction that occurs at the negative electrode
(cathode) produces:
A. Hydrochloric Acid
B. Sodium Hydroxide (Lye)
C. Oxygen Gas
D. Chlorine Gas
Answer: B
Conceptual Explanation: Galvanic electrolysis uses direct current to produce sodium
hydroxide (lye) at the cathode to decompose the hair papilla.
2. According to Faraday’s Law, the amount of lye produced is equal to:
A. Voltage multiplied by Resistance
B. Watts divided by Time
C. Milliamperes multiplied by Seconds
,D. Current divided by Voltage
Answer: C
Conceptual Explanation: Units of Lye (UL) = mA x Seconds. This formula determines the
chemical energy delivered to the follicle.
3. Which hair growth stage is considered the most effective for permanent hair removal in
both electrolysis and laser?
A. Catagen
B. Telogen
C. Anagen
D. Exogen
Answer: C
Conceptual Explanation: Anagen is the active growth phase where the hair is still
attached to the dermal papilla, allowing for direct destruction of the germinative cells.
4. In Thermolysis, the heat is greatest at the tip of the needle. This phenomenon is known as:
A. Ohm’s Law
B. The Faraday Cage
C. The Point Effect
D. The Joule Effect
, Answer: C
Conceptual Explanation: The point effect describes the concentration of high-frequency
current at the tip of the probe, creating the highest temperature there.
5. Which laser wavelength is considered the ‘Gold Standard’ for Fitzpatrick Skin Types I-IV?
A. 1064 nm (Nd:YAG)
B. 810 nm (Diode)
C. 694 nm (Ruby)
D. 755 nm (Alexandrite)
Answer: D
Conceptual Explanation: The Alexandrite laser (755 nm) is highly absorbed by melanin,
making it very effective for lighter skin types.
6. The process where a laser beam is converted into heat to destroy a specific target is called:
A. Spontaneous Emission
B. Photoelectric Effect
C. Selective Photothermolysis
D. Radiative Transfer
Answer: C
