The treatments you have both been using are all good to get some improvement for acne scars. In my opinion, the most aggressive choice (with the best results) is dermabraision. Not microdermabraision, but the full fledged dermabraision. The recovery is 2-3 weeks initially and you can expect redness that will subside over many weeks following that. But the results will be the best of all the treatment options. If you prefer a faster recovery with somewhat more limited results I might recomend fractional CO2. I use the Matrix in my practice, but there are many machines out there and they all do basically the same thing. These treatments will require about one week of healing and you may have some minor redness that improves quickly after that. Fractional CO2 lasers are not as aggressive as dermabraision and will not give you as nice a result from one treatment. You may need to have a couple of treatments over time to achieve a similar result in the end.

I hope this info helps!
