Can ablative CO2 laser make red scars worse? (skin type 1-2)

Question

I have a 6 months old rolling scar on my cheek which is still very red. Yesterday I had an appointment with a dermatologist and he told my that he wants to treat me with a CO2 Laser but I will need some Radiofrequency microneedling sessions first, because the scar is still red. Why can't I have CO2 Laser on red scars? I thought it would be even better to treat them early with laser? Can CO2 really worsen the PIE? (except for the natural redness after the treatment)

Jeff Rapaport, MD · Answer

CO2  laser can be performed on red scars. Your physician may be trying to lift this scar before performing the procedure by utilizing radiofrequency micro-needling. Another option would be to perform subcision and use a vascular laser or IPL. CO2 can then be performed if needed.Jeff Rapaport MD FAADRealself All-star

Your dermatologist is correct, CO2 will certainly make PIE or red scars worse, and hence the logic in performing RF microneedling. The other option is to use vascular lasers such as Prima or V Beam, or even IPL- BBL to address the redness. There are may other variables as to the logic of recommendation of treatments. Dr Davin S.
