Hi. I believe the Perfecta is the VBeam laser made by Candela. Did you have treatment done at U of L or at UK Med Center in Lexington? They have the most up to date equipment in the state. They use the VBeam on my grandson at UK.
Also, the doctor's experience with laser treatment is a factor, as well as the thickness, location, etc. of the individual's pws. My grandson sees Dr. Henry Vasconez at UK. Who is your doctor and which VBeam did they use?
