Effective application
Position the CryoPen correctly
Before starting treatment take into account age, location, size and number of lesions, skin
type, degree of tanning and season.
The applicator tip (from where the liquefied N O flows) should be held 0,5 to 3 mm from
2
the lesion. Further than 5 mm from the applicator tip the liquefied N O will have expanded
2
into gas phase which is not effective for achieving therapeutic results.
By approaching the lesion with the gas flowing you will observe the focal point of the jet
on the tissue. The closer you approach the lesion, the more freezing power you apply
Distance to lesion
to the tissue. It is recommended to keep a greater distance for the smaller and more
delicate procedures.
The amount of liquid N O that you wish to apply can be controlled by moving
2
the applicator quickly towards and away from the tissue. Circular and crossing movements
have the same effect.
