ELECTROLYSIS IBEC+LASER STATE BOARD
EXAM BANK 2024/2025 | ACCURATE REAL
EXAM VERSIONS WITH ACTUAL QUESTIONS
AND VERIFIED ANSWERS | EXPERT VERIFIED
FOR GUARANTEED PASS | LATEST UPDATE
Question 1: If the time of pulse duration is changed from milliseconds to nanoseconds, the
laser is what?
Answer: Q-switched
Rationale: When pulse duration shortens from milliseconds to nanoseconds, the laser
operates in a Q-switched mode. This produces extremely short, high-intensity bursts of
energy, ideal for targeting pigment particles or tattoo ink without excessive heat damage to
surrounding tissue.
2. Which tissue chromophore primarily absorbs the wavelength of a ruby laser?
Melanin
Melanin has a strong absorption peak at the ruby laser wavelength (694 nm), making
it effective for hair removal and pigmented lesion treatments.
3. What is the primary purpose of cooling the skin during laser hair removal?
To protect the epidermis
Cooling reduces epidermal temperature, minimizing the risk of burns and post-
inflammatory hyperpigmentation while allowing safe delivery of laser energy to the
follicle.
4. In electrolysis, what modality uses both heat and chemical action for hair
destruction?
Blend
The blend method combines thermolysis (heat) and galvanic (chemical) methods,
increasing effectiveness in destroying the hair follicle.
5. What is the target tissue for laser hair removal called?
Follicular papilla
The follicular papilla contains the blood supply and stem cells needed for hair growth,
making it the key structure to destroy for permanent hair reduction.

  1. Which wavelength penetrates deepest into the skin? 1064 nm Nd:YAG Longer wavelengths penetrate deeper due to lower scattering in tissue; Nd:YAG is preferred for deeper follicle targets and darker skin types.
  2. What is the effect of increasing spot size on laser penetration? Increases penetration depth Larger spot sizes reduce scattering, allowing light to penetrate deeper into the skin.
  3. What skin type on the Fitzpatrick scale is most at risk of hyperpigmentation after laser? Type IV–VI Darker skin contains more melanin in the epidermis, which absorbs laser energy and increases the risk of pigmentary changes.
  4. Which electrolysis modality is the fastest? Thermolysis Thermolysis uses high-frequency current to generate heat almost instantly, making it the fastest hair removal method per follicle.
  5. What is selective photothermolysis? Targeting specific chromophores with specific wavelengths and pulse durations Selective photothermolysis is the principle that allows lasers to target pigment or vascular structures without damaging surrounding tissues.
