Hi Docs,

I have some mild to moderate rolling scars on my cheeks. I have done 2 sessions (Sep 2017 & Oct 2017) of subcision with some improvement (~30%). I was advised to do fractional CO2 asap next. My questions are:

  1. Does the amount of time between the subcision and fractional CO2 session affect the fractional CO2 effectiveness? I was told that I have to do the CO2 as soon as possible, or at least within 6 months, otherwise it will be less effective.
  2. Besides hyper-pigmentation, what are the risks of fractional CO2?
