LASER HAIR REMOVAL EXAM 2025
QUESTIONS AND ANSWERS
Which of the following is NOT a property of laser light? - ANS It's not always visible, they are
also monochromatic, collimated and coherent
true or false: priorto treatment, hair should neither be shaved or waxed. - ANS true
joules per area equals: - ANS fluence
In the field of aesthetics, there are several types of lasers that produce energy within specified
durations and characteristics. which one of the following is most appropriate for laser hair
removal? - ANS long pulsed lasers
the outermost layer of the skin is called the: - ANS epidermis
on the fitzpatrick scale of skin prototypes, caucasian skin that burns mildly but will tan is best
described as skin type : - ANS III. I never tans, II burns, tans but doesn't last long, IV is olive
complexion, V light dark skin always tans, VI very dark
which one of the following is a correct match? - ANS Diode: 810
Ruby: 694
Alexandrite: 755
ND Yag: 1064

, each tissue has specific absorption characteristics based on its: - ANS chromophores
finding the optimal treatment settings is a balance of: - ANS efficiency and safety
Increasing spot size keeps scattered photons in the: - ANS beam path
minimize direct reflection by keeping incident path ______ to skin surface. -
ANS perpendicular
which of the following contributes the least to the efficacy of the treatment? - ANS pulse
rate/ hertz. we are more concerned with pulse width or duration, wavelength , and amount of
fluence.
which of the following is not a primary layer of skin: - ANS photodermis
when speaking of medical laser systems, It's perhaps most appropriate to think of them as tools
for a specific job. which one of the following is NOT one of the most basic considerations for
selecting the best tool for the job? - ANS the power supply. we are more concerned with
pulse width or duration, wavelength , and amount of fluence.
which of the following is not a form of cooling? - ANS electromagnetic cooling. cooling forms
are cryogenic , forced air and contact.
known as the workhorse laser, which of the following lasers/ machines is most appropriate to
treat skin types IV, V and VI for LHR? - ANS ND:YAG 1064
which one of the following wavelengths is most appropriate for the treatment of LHR, certain
pigmented lesions, tattoo removal, and vascular lesions? - ANS 1064 nm because it goes
further into the skin.
