ELECTROLYSIS IBEC & LASER STATE
BOARD TEST EXAM 2026 QUESTIONS
AND CORRECT ANSWERS.
1. Which phase of the hair growth cycle is considered the most effective for permanent hair
removal treatments?
A. Telogen
B. Catagen
C. Exogen
D. Anagen
Answer: D
Conceptual Explanation: Anagen is the active growth phase where the hair is still
attached to the dermal papilla, making it the most vulnerable to destruction by electrolysis
or laser.
2. In Galvanic electrolysis, the chemical reaction that occurs at the negative electrode
(cathode) produces:
A. Hydrochloric acid
B. Oxygen gas
C. Sodium hydroxide (Lye)
,D. Chlorine gas
Answer: C
Conceptual Explanation: Galvanic electrolysis uses direct current to produce sodium
hydroxide (lye) in the follicle, which chemically destroys the hair germ cells.
3. The principle of ‘Selective Photothermolysis’ in laser hair removal relies on which three
factors?
A. Voltage, Amperage, and Resistance
B. Frequency, Amplitude, and Spot Size
C. Wavelength, Pulse Duration, and Fluence
D. Density, Mass, and Volume
Answer: C
Conceptual Explanation: Selective photothermolysis requires the correct wavelength for
the target chromophore, enough fluence to damage it, and a pulse duration shorter than the
thermal relaxation time.
4. Which skin layer contains the melanocytes responsible for skin pigmentation?
A. Stratum Corneum
B. Subcutaneous layer
C. Reticular Dermis
D. Stratum Germinativum (Basale)
, Answer: D
Conceptual Explanation: Melanocytes are located in the bottom layer of the epidermis,
the stratum germinativum, where they produce melanin.
5. What is the effect of high-frequency current used in thermolysis?
A. Electro-coagulation through heat
B. Chemical decomposition
C. Ionization of salts
D. Production of acid at the needle
Answer: A
Conceptual Explanation: Thermolysis uses high-frequency alternating current to cause
molecular vibration, creating heat that coagulates the tissue (electro-coagulation).
6. A Fitzpatrick Skin Type IV is characterized by:
A. Always burns, never tans
B. Fair skin, blue eyes, high sun sensitivity
C. Mediterranean/Olive skin, tans easily, rarely burns
D. Deeply pigmented dark brown skin, never burns
Answer: C
