Can I do CO2 Fraxel after TCA Cross when there are still scabs on my face?

Hello, I did TCA CROSS about 5 days ago and now I have bunch of brownish scabs all over my face. They haven't fallen out yet and I'm planning to do CO2 fraxel tomorrow. should I wait until those scabs are all falling off and do CO2 fraxel or is it okay to do it even when there are scabs on my face? Thank you very much. P.S: I first thought those brownish scabs were some kind of hyperpigmentation but later I found out it was scabs. Does scabs after TCA CROSS usually looks like brownish spots?
