What are considered conservative settings for a fully ablative CO2 laser?

Co2 laser skin resurfacing is a powerful treatment that can be very effective if administered properly. The settings are based on several factors and require an in-person consultation to determine what the appropriate settings would be and if the patient is a candidate for the treatment. Trust your face to a board-certified physician or nurse who has extensive experience with Co2 laser.

Thank you for your question!  Unfortunately, it's difficult to determine the best solution for you without the benefit of photographs or a formal evaluation. Generally speaking, scars can be improved with a combination of surgery and/or lasers and microneedling with PRP. Below is a more detailed reference list of the treatments available.  1. Vascular lasers (Yellow laser, V-Beam, Excel V) 2. Fractional lasers (Fraxel, Erbium, CO2) 3. Microneedling/PRP 4. Silicone-based scar gels with growth factors 5. Excision / revision surgery At our practice, we suggest medical-fgrade skincare and microneedling/PRP which you can get at emeragecosmetics.com along with a free skincare consults. I recommend getting a formal evaluation with a scarring expert to determine which is best for your specific case. Best, Dr. Emer

I recommend on my experience to treat scars on the skin type that you have to be done by ablative fractional laser, both CO2 or Erbium.
Full Ablative is not the recommended even on conservative setting. 
You should look for experts on the skin to be treated more than the setting or wavelength.
