I had a massive break out this summer after 1.5 years of clear skin following roaccutane 01/2015-06/2015.

I have also had a previous round of roaccutane that kept me clear for 4 years 06/2009-09/2014.

The break out was sudden and lasted multiple months. I finally went to a derm who gave me duac, doxycycline and differin. 
I came off the doxy after 6 weeks. The duac was great and I stopped using it after 12 weeks to try and avoid antibiotic resistance. Im still using the differin at night to keep my cheeks clear and help heal whatever these are ( I suspect ice pics and some boxcars with a touch of hyperpigmentation?). I've also added in Sallycylic acid in the am and benzoyl peroxide 2.5 % for my forehead as it has always been a bit temperamental but clears up quickly with BP.  

My skin is quite red since I added in the the SA but I think it will calm down soon (hopefully).

My question is, what exactly are these scars? And will they heal?  Should I be doing anything else to help them?
