Fractional co2 intervals between session, how long?

I tell my patients to wait 4-6 weeks between sessions, it allows time for skin to heal and get ready for next session.  Make sure to sunblock. Sunblock is key after treatments are preformed. The less sun exposure the better. Goodluck.

The density of fractional laser resurfacing and your skin type will play an important part regarding intervals. For fair skin, I usually wait 4-10 weeks, for darker skin types, usually 6-12 weeks. The use of SPF and bleaching agents can also help reduce unwanted pigmentation between treatments. All the best, Dr Davin S. Lim 

Yes. My policy is to wait at least 4 weeks between treatments. Having a 10 week interval will in no way compromise your results. Of course, you will want to be very precautions with sun exposure for several weeks after treatments. I hope this helps.
