LASER HAIR REMOVAL NEW EXAM WITH COMPLETE
SOLUTIONS
which of the following is NOT a property of laser light? - ANSWER Its not always visible,
they are also monochromatic, collimated and coherent
true or false: priorto treatment hair neither should be shaved or waxed. - ANSWER true
joules per area equals: - ANSWER fluence
Aesthetic Question Bank In aesthetics, a number of lasers produce energy within
specified duration and characteristics. Which one of the following is most appropriate
for laser hair removal? - ANSWER long pulsed lasers
The outermost layer of the skin is known as the: - ANSWER epidermis
Skin prototypes, caucasian skin that burns mildly but will tan is best described as skin
type : -ANSWER 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? -ANSWER
Diode: 810
Ruby: 694
Alexandrite: 755
ND Yag: 1064
, each tissue has unique absorption characteristics based on its: - ANSWER
chromophores
determination of treatment variables is optimization of - ANSWER efficiency and safety
Larger spot size retains scattered photons within the - ANSWER beam path
Eliminate direct reflection by keeping incident path ____ to skin surface. - ANSWER
perpendicular
Which of the following contributes the least to the efficacy of the treatment? - ANSWER
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: - ANSWER photodermis
When discussing medical laser systems, perhaps the best way to think of them is as
tools for a specific task. Which of the following is NOT one of the most fundamental
factors when attempting to select the right tool for the job? ANSWER: The power supply.
We are more concerned with the pulse width or duration, wavelength, and amount of
fluence.
Which of the following is not a form of cooling? - ANSWER Electromagnetic Cooling.
Forms of cooling are cryogenic, forced air and contact.
Said to be the workhorse laser, which one of the following lasers / machines would be
most appropriate for treating skin types IV, V and VI for LHR? - ANSWER ND:YAG 1064
Which of the following wavelengths, given the treatment of LHR, certain pigmented
lesions, tattoo removal, and vascular lesions is most appropriate? -ANSWER 1064 nm as
it goes deeper in the skin.
removing tissue and inducing thermal injury that heals by epidermal regeneration and
