Although most patient's redness resolves 1-2 weeks after Fractional CO2 laser, it is not uncommon for the face to continue to be red or flushed up to a month after Fractional CO2 treatment. I note that subcision was also done and PRP was used. As such, redness may persist for a longer time.
After laser treatment, to facilitate recovery, it is recommended to wash the treated area with water regularly, avoid excessive sun exposure, and apply sunscreen.
It would be best to speak to your doctor to discuss the timing of your second procedure.
