Hi,
Thank you for your photos.
From the photos, you do have rolling and box scars.
I personally combine Subscision and a Fractional Laser (eCO2 etc) for such scars so as to treat each scar type optimally. Besides the machines/methods used, experience also plays an important part as there are hundreds of settings for each laser and different techniques for each treatment.
Downtime and redness is to be expected from a few days to a week on average.
Multiple treatments are required and spaced at least a month apart.
Hope that helps.
All the best!
