Hi there,
You do have a combination of deep Box scars, Ice pick scars and some that are tethered down.
Personally, I would recommend a combination of treatments involving Subscision, TCA CROSS and Skin Resurfacing modalities (Co2, Erbium, Microneedle RF) as these treatments are able to treat each scar type optimally.
Multiple sessions will be required and treatment is to be done at least 4 weeks apart. Downtime / redness will be expected for a few days to a week on average.
Do speak with your treating physician on the pros / cons of each treatment.
Hope that helps.
All the best!
