Can a repeat of CO2 ablative resurfacing correct damage caused by the first treatment?

This is difficult to answer without pictures. Lasers like Co2 work best in combination with other treatments in order to improve the skin's texture and collagen. After Co2, I recommend adding fraxel lasers, microneedling/prp and radiofrequency treatments.  I recommend following up with a cosmetic dermatologist for after care and treatment. Best, Dr. Emer

Thank you for your question 2017hopeful.
I am sorry to hear about your situation. Fractional CO2 laser resurfacing is an
outstanding treatment that can address multiple aspects of aging in a single
treatment. Surprisingly, with many cosmetic treatments complications can be addressed by repeating the same treatment again. However, the settings must be adjusted. Please consult with a doctor for
specific recommendations. Good luck!
