LASER HAIR REMOVAL PRACTICE
2024-2025 EXAM QUESTIONS AND
ANSWERS
Coherent energy - Answer-Laser photons travel through space both temporally and
spatially.
Travel in Time and space in perfect unison in one direction. In phase or in step
Monochromatic - Answer-Laser light is composed of one wave length and one color
weather visible or invisible
Collimated - Answer-Photon are parallel to each other in a diameter of the beam to
produce a focused spot by using a lens
Fluence - Answer-The energy of the pulsed laser beam it is expressed in joules per cm2
Joule - Answer-The unit of energy or work
NS. Nanosecond - Answer-Pulse duration or width is measured in
Spot size - Answer-Spot size is measured in mm. Millimeters
Optical energy - Answer-Is determined by the lasers power,spot size and the pulse
duration or pulse width
Laser lens - Answer-Can be used to adjusted the intensity to be used for cutting,
coagulation, or heating
NG YAG LASER - Answer-Is a solid state laser
Laser therapies - Answer-Laser hair removal
Tattoo removal
Teeth whitening
LASIK
Vascular lesions
Pigmented lesions
Selective photothermolysis - Answer-By selection of a specific wavelength unique to
one target chromophores. Heat can be delivered rapidly to the target before it can affect
the surrounding tissue
, Melanin Chromophores - Answer-Melanin for hair removal
Hemoglobin chromophores - Answer-Hemoglobin , vascular targeted for spider veins
H2o water chromophores - Answer-For resurfacing water is targeted since the body and
tissue is made up of mainly water.
TRT
Thermal relaxation time - Answer-Is the amount of time necessary for the target to lose
50% of the heat
Laser penetration depth - Answer-Penetration of laser depth from shallow to deepest
Ruby , Alex,diode , nd yag
FDA approved IPL for cosmetic use in the mid 1990s - Answer-The mid 1990s the FDA
approved intense pulse light for various cosmetic defects including pigmented and
vascular lesions as well as hair
IPL wavelength - Answer-400-1200 nm
IPL - Answer-IOL emits every wavelength of light 400-1200. Lasers emit only one
wavelength
Lasers emit only one wavelength of light - Answer-
RF. Radio frequency - Answer-Alternating energy waveforms that produce localized non
specific heat to the epidermis or dermis
RF energy - Answer-Is color blind enhancing safety. And is widely used in cellulite and
skin tightening treatments
The top 5 non- invasive cosmetic procedures - Answer-1. Neurotoxin injection
2. Dermal fillers injection
3. Chemical peels
4. Last hair removal
5. Microdermabrasion
DSHS. - Answer-Department of State Health Services
DSHS - Answer-Laser radiation program covers technicians for laser hair removal
Level of laser techs - Answer-1. Apprentice in training
2. Technician
3. Senior technician
4. Professional technician
