ANATOMY
This is the outermost layer of the skin and acts as the body’s first line of defense.
What is the epidermis?
This type of radiation, used in cosmetic lasers, is considered safe because it doesn’t damage DNA.
What is non-ionizing radiation?
This term refers to the distance between two peaks in a wave and is measured in nanometers.
What is wavelength?
The wavelengths that make up an IPL treatment.
What is 400-1500nm?
The mode that the laser should be in when not in use
What is standby?
For laser hair removal to be effective, the hair must be in this active growth stage.
What is the anagen phase?
These wavelengths are stronger and more energetic, but don’t travel deeply into the skin.
What are short wavelengths?
This laser parameter describes the surface area of energy applied to the skin and is often measured in mm.
What is spot size?
The laser setting most associated with adverse reactions.
What is fluence?
Risk of treating someone with an active tan (Name 3)
What are burns, blisters, hypo/hyperpigmentation?
Found in the basal layer of the epidermis, these cells are responsible for producing melanin.
What are melanocytes?
The optical resonator contains this to produce the desired wavelength.
What is an active medium?
The setting used to intensify the laser pulse without adding any heat.
What is pulse duration (ms)?
FOR BONUS POINTS:
WHAT IS MORE AGGRESSIVE A HIGHER OR LOWER MS?
The lasers that are used for skin rejuvenation and ablative skin resurfacing.
What is the Erbium YAG (2940nm) & CO2 (10,600nm)?
What clinical endpoint is based on
What are visual cues & client discomfort?
This protein found in the dermis is crucial for wound healing and gives skin its strength.
What is collagen?
This term describes how photons in a laser beam travel in a synchronized wave pattern, maintaining equal distance between energy peaks.
What is coherence?
This process occurs when laser energy is absorbed by the chromophore, converted to heat, and damages the target.
What is selective photothermolysis?
The wavelength for the Pulsed Dye Laser (PDL).
What is 500-600nm?
FOR BONUS POINTS:
WHAT IS THE KTP WAVELENGTH?
The device needed to reduce plume in the air from ablative laser procedures.
What is a buffalo vac?
In this layer of the epidermis, cells begin to flatten and lose their nuclei and organelles.
What is the stratum granulosum?
This part of the laser system surrounds the active medium and includes mirrors that amplify light.
What is the optical resonator?
FOR BONUS POINTS:
What 3 things are in the optical resonator?
This term refers to the amount of time it takes for a target to lose at least 50% of its heat to surrounding tissues.
What is thermal relaxation time (TRT)?
A laser pulse lasting one billionth of a second is known by this term.
What is a nanosecond?
The 3 primary laser chromophores
What is hemoglobin, water & melanin
