The Q-Switch laser creates what effect in the skin?
Photo acoustic pressure
How does photo acoustic waves work in the skin?
The short and quick pulses prodce a pressure wave damaging the collagen initiating an inflammatory healing response. Producing new collagen & elstain

Can the 1540nm laser be used on all skin types?
Yes, but heed caution with darker skin types
What is the 1540nm laser intended for?
Coagulation of soft tissue & Non-ablation
What is the mechanism of action for the Clear Skin Pro for skin rejuvenation and how does it work?
Fractional non ablative treatment causing columns of tissue damage into the dermis by absorbing water in the skin and converting it into heat. The great thing about fractionated treatments, it has good tissue between the damaged tissue/denatured proteins (eg collagen) this will trigger an inflammatory reaction and wound healing will take place healing and creating new tissue. The ‘good tissue’ will aid in the faster recovery of the skin and new collagen will be synthesized by the extra cellular matrix remodelling. This treatment will assist with fine line and wrinkles.
Is cooling recommended when using the Clear Skin Pro?
YES
When using the 1540nm Clear Skin Pro, would you stack or not?
Yes you would stack. The amount of stacks is dependant on the skin type and outcome wanted.
Which hand piece and beam would you use when treating active acne?
You would use the Clear Skin Pro using a full beam.
Explain the process when treating active acne?
The skin will absorb the water and convert it to heat. It will deliver it below the lesion, however because it is a full beam and lower fluence/energy, it will dry out the sebaceous gland and surrounding tissue. This changes the environment for the p-acne bacteria making it unfavourable for the bacteria to live in & reducing the proliferation of the bacteria.
Is cooling and vacuuming needed when treating acne bacteria?
YES
When using the vacuum tip on the Clear Skin Pro, how do you move it around on the skin?
The most effective way to move the tip/hand piece around is to break that suction by tilting it about 45 degrees and then movie it to another area.
When treating benign lesions using the Clear Skin Pro,
What tip should be used?
Should the vacuum be used?
Should the cooling be on or off?
What tip should be used? - 2mm
Should the vacuum be used? - NO
Should the cooling be on or off?
OFF
What is the LP NdYag for?
This hand piece is specifically for deep vascular lesions
What is the wavelength for the LP NdYag?
1064 nm

What does Yag stand for in NdYag?
Yttrium Aluminum Garnet
What does Nd stand for and mean?
Indicates that some small percentage of the yttirum atoms have been replaced by neodynium ions
What are the available tips for the LP?
2mm, 6mm & 10mm
What is the mechanism of action on the LP
Photothermolysis. The heat will be absorbed by the blood within the blood vessels causing heat and destruction of the blood vessel walls and cause coagulation of the tissue

What does AFT stand for and what is it?
Advanced Fluorescent Technology. Basically, this is IPL which uses a xenon flash lamp emitting a range of wave lengths from 450nm to 950nm.
What does EDF stand for and what is it?
Equal Distribution Fluence. What this is, is the energy/fluence output is delivered evenly over a period of time as opposed to multiple peaks of energy over a period of time. The EDF allows for a safer and more effective treatment.
“In Motion” allows for what?
A safer treatment. Gradual increase in temperature of the target. Faster rep rate, lower energies.
Dye VL used for & for what skin types
Dye VL is used for pigmented and vascular lesions. Used for skin types I-IV.
What is the wavelength of the Dye VL
500nm - 600nm
What are the two modes of treatment for the Dye VL
1) In Motion (VL)
2) Stationary (SVL)
What is used topically when using the Dye VL in motion and why?
Ultrasonic gel.
Maximise absorption and minimise reflection.
Also useful for better gliding and surface cooling.
What are the two chromophores that the Dye VL targets
Melanin and Haemoglobin
Is the SVL in motion or stationary?
In Motion
The Dy SVL
in-motion technique is based on a concept of what?
Low fluence and high repetition rate of pulses that are emitted gradually over an area and a period of time.
Explain how the
in-motion technique works
This works by accumulating energy in cycles. Eg if the cycle is for 30 seconds, it will pulse for 30 second and then stop for 6 seconds. During this time, continue to move the hand piece to cool the skin and then the system will continue with another round of 30 seconds until the accumulated energy has been reached. Once this area has been completed, then move on to another grid/area.
What is the grid recommended grid size for the Dye VL?
100cm2
What are the treatment intervals when using the Dye VL and what is the recommended number of treatments?
Treatment intervals 2-3 weeks and
Number of treatments 3-6
When treating using the Dye VL on VL mode (stationary), do you stack or overlap?
No, there is no stacking and no overlapping
Is the energy higher or lower in the stationary mode?
The energy is higher

550nm - 650nm
What skin types is the Dye SR suitable for?
Skintypes I-V
