Jessners definitely worth a go. I've used Skin Obsession (check out Amazon reviews) myself - as you know the application method now you're fine to DIY IMHO.
Also, I use a Derminator shop.owndoc.com/product-info.php?Derminator-pid256.html for info incl vids and instruction manual. I was an early adopter and have used it for maybe 2.5 years. Very happy.
With either peels or needling, you will get much better results if your epidermis it primed for regeneration (i.e. regeneration from the deliberate damage you're incurring to trigger new collagen and surfacing).
So, before you do another peel/needle at all, you should ensure you're on a regiment of retin A (or high dose retinol) and vitamin C (either topical or high dose supplementation)for at least a month. Just my humble opinion. Also an excellent UVA-protective sunscreen = non-negotiable.
Without this priming and protecting regime both before and after (although dont use the topicals for at least a week after procedure) you are unlikely to get sufficiently good results out of peeling or needling that justify the downtime. In fact, you could be worse off than when you started.
If you do prime/protect and follow the procedures/frequency precisely as per instructions, (be aware you need 4-6 session of either option), then I am pretty sure you could see some significant improvements at relatively low cost.
Any questions, let me know. Any questions, happy to help.
