Is it safe to do a profractional laser before a CO2Re laser?

Is it safe to do a Sciton Profractional laser 5 1/2 weeks before getting a CO2Re laser resurfacing? If not, how long would I need to wait to try a profractional laser or RF microneedling treatment after my CO2Re laser? Also, I am in my early 40s. How much improvement might I see in my acne scars? They are mostly old rolling scars. Thank you!!
