Picoway vs Q Switch for cafe au lait birthmark removal.

Question

I have a CALM on my face, I'm American very light skin. Which laser equipment is better? If going with Quote Switch if it doesn't work can I then be treated with picoway or would it be too late. Can laser make it worse? Thanks

Hi, 
Pico second lasers such as the Picoway, are simply an advancement over the earlier Q Switched lasers. The wavelength of my Picoway laser and my Q switched laser is the same - 1064 nm( other wavelengths are also there, just an example),  but the Picoway is much more powerful as the laser delivers the energy in picoseconds as compared to my Q switched, which delivers the energy in a matter of nanoseconds. This is the main difference - but this translates into higher power to break down the pigments more effectively, and lesser damage to the surrounding tissue. I upgraded to the Picoway from a Q switched, for precisely these reasons. 
If you have the option of choosing between a Picoway and a Q switched laser for your CALM, do consider the Picoway. 
Good luck!
