This chromaphore is the target for pigmented lesions
What is melanin
100
This is the main indication of skin tightening devices for facial treatments
What is laxity or wrinkles
100
This is the primary principle behind laser and IPL hair reduction
What is the theory of selective photothermolysis
100
This gland can shrink within a tx with lasers to help battle acne
What is sebaceous
200
In order to be affective this aspect of a tx has to be shorter than the pulse duration of hemoglobin; a time for the chromaphore to lose 50% of it's heat
What is the thermal relaxation time
200
These types of lasers give off a photoacoustic response in the skin and are commonly used for the the treatment of lentigos, age spots, melasma, seborrhea keratosis, and some birthmarks
What is a Q-Switched Laser
200
Radiofrequency uses alternating energy waveforms that produce localized, non-specific heat up to and within this layer of skin
What is hypodermis
200
The active medium for the Asclepion MeDiostar is this
**BONUS** name the wavelength of the machine
What is a diode
**810nm
200
This coloured spectrum of visible light interacts with P. acne naturally producing porphyrin
What is the blue spectrum
300
This colour of the visible spectrum is commonly used for the tx of vascular lesions
What is yellow or green (500nm-600nm)
300
This could develop on the skin even after several treatments with a laser depending on the type of lesion and whether the appropriate sun protection is used
What is re-pigmentation
300
This is the path in which electrical energy travels
What is the path of least resistance
300
This machine is the best for the darker skin types but is definitely the most painful wavelength for hair removal
What is the Nd:YAG 1064nm
300
This type of laser tissue effect occurs in the skin when a chemical reaction occurs resulting in reactive free radicals destroying bacteria
What is photodynamic photobiochemical or photochemical
400
This wavelength for an Nd:YAG is more affective for larger diameter facial vessels and leg veins because of it's deeper penetration
What is 1064 nm
400
Aestheticians must be sure that melanin-containing lesions are not this, before treatment
What is pre-cancerous or are non-cancerous
400
This component of certain radiofrequency devices is placed on a distant point from the treatment area to disperse energy
What is a grounding pad
400
This laser hair removal device originated in the 1990s but has become obsolete in practice
**BONUS** name the wavelength
What is the Ruby Laser
**694nm
400
This type of light source uses a broad spectrum blue light flash lamp for the tx of mild to mederate acne on the face, back, and chest
What is a LED light source
500
This pigmentary disorder is misunderstood, being that it is actually vascular and hereditary, and it can be treated with multiplex technologies (different wavelengths)
What are port wine stains
500
This type of laser/light source runs at 755nm and grabs pigment best when it is Q-switched
What is an Alexandrite
500
This type of laser technology is used in combination with radiofrequency to bump up potentcy
What is ELOS
500
This machine has the second highest melanin attraction on the absorbtion curve and is very affective for skin types I-IV
What is Alexandrite 755nm
500
This wavelength of the Cool Touch (Nd:YAG) machine can be benficial for thermal injury to the sebaceous glands
