5 weeks after CO2 procedure, no improvement in texture and shape of laser marks - permanent damage? (Photo)

you should be started proper skin care, non ablative lasers and microneedling/PRP for healing.  Best, Dr. Emer.

I would suggest giving it more time, the full healing can take months, depending on settings used, and laser can also be used to help any potential issues. I would follow up with your provider for further help

I am sorry you are experiencing this after your CO2 treatment.  I am not surprised about the lingering redness.  I tell clients that everybody is red for at least 4 weeks and many are for 10-12.  The redness does eventually go away.  If it seems especially stubborn, we will do a few treatments of laser Genesis, which is a very gentle, no down-time laser.
The hypertrophic scars with visible dents are more unusual and concerning.  I would not panic yet, though.  Try and be patient for another 3-4 months.  If, at that point, your skin is still showing scars, you could consider either micropen treatments and/or steroid injections.  I would not begin those yet, however.  If you want to do something now, I highly recommend Infrared light treatments after CO2 lasers.  I find that they stimulate healing and improve outcomes.
Best of luck to you.
