Dermapen Damaged My Skin, Opened Pores and Caused Scars

At the end of September 2017 I received a Dermapen treatment to help close pores and clear some acne scars on my face. This has turned out to be one of the biggest mistakes I've ever made, and I'd urge those with sensitive/acne prone skin to avoid this treatment and stick to natural remedies - I've learned this the hard way. I'm sharing my story to hopefully reach out to others who have experienced this reaction, to share any post-treatment care & ways that my skin may heal.
Before I received the Dermapen treatment I did research & figured out that it couldn't make my skin any worse than it already was (how wrong was I?!) and that, if anything, my skin would either stay the same or improve. My Dr reassured me that there was only a few days of downtime (which wasn't the case for me at all) and that it would tighten my pores/clear my complexion. My skin was red/raw for at least a week following my treatment, I was given a tiny post-treatment cream which I have now discovered was full of irritating chemicals. I stuck to using The Ordinary's Hyaluronic Acid 2% + B5, Plant Derived Squalane and Clinique's "Take The Day Off" Cleansing Balm, this seemed to calm my skin down after a few weeks but the holes/open pores are still there and worse than ever. At this point I'm trying to baby my skin as much as possible, letting it breathe and not using any harsh chemicals.
I'm going to use this feed to update but after reading various feeds on here with people who have had similar experiences I'm not expecting much improvement, unless there is some miracle cure! I've realised now that my skin is severely dehydrated and that the Dermapen has damaged the structure of my skin. The pores are now joining together to form wrinkles on my face, and at 23 years old my facial skin looks around 10 years older. This has completed ruined my confidence and I've even been struggling to leave the house because of it as I can't even hide the damage with make-up - if anything it only highlights the holes in my skin. My hope is that my skin repairs itself to a point where I can just get on with my life without worrying about how horrible it looks.

In my initial post I stated that I got the treatment in September when it was actually at the end of August. Sorry for the confusion!

As you can see, almost no improvement - in fact, the pores are joining together and it looks like I have wrinkles on my t-zone. I guess the only saving grace is that the damage is only in that area, but my pores have been stretched. I've stopped using oils as I think it was making the damage worse, I've swapped to using Dr Jarts ceramidin cream & some gentle avene products. Nothing harsh at all! Does anyone know if there's a way to get rid of these lines or stop my pores from fusing together? I'm at a complete loss, every day is a struggle to live my life when I'm so self conscious. Make-up only highlights the damage.
