I am not a doctor so I am unqualified to answer your question. However I
think you are doing the right thing in getting some other opinions. The
treatment seems very radical to me. I have had numerous solar ketoses
removed from my face, especially nose, and arms over the years by freezing
with liquid nitrogen. In fact it seems like I have had it done about once a
year for over 20 years by my Kaiser doctors. The liquid nitrogen raises a
small blister that includes the rough skin and it peels off in less than a
week and that is all there is to it. I hope this has been some help.
