I started electrolysis around the same time you did - mid July this year. I have/had dense hair on my chin and some under my chin/neck area. It took 6 1-hour treatment sessions to fully clear the area and I have been going back for 20 minutes once per week to get the stragglers. My electrologist is using thermolysis.
My first 2 treatments, I had a LOT of swelling and redness and my treatment area actually felt numb. My next few appointments had less swelling but still some redness about 2-3 days after the sessions and little numbness. I haven't had any pinprick marks or any acne at all. Sometimes right after the session, my skin will look like it has a few mosquito bites (I very seldom hear a sizzle sound which I think is what is creating those mosquoto-bite-looking marks). I have had some scabbing that isn't noticable. The only after-affects that I have noticed recently are the redness after the sessions and I feel some tingly/pinching sensations under my skin which I assume is part of the healing process (although I haven't read about anyone else experiencing this). I don't know if I would describe the area as raw, but mine is a bit tight as well.
That being said, I'm just a customer and have no knowledge about your electrolysis. I don't have any of the pits or wrinkles (yet). From what I have read, those who do get pits, they don't usually show up for a few months after treatment.
For my after treatment, I wash my face with diluted Castille soap a few times per day and put refrigerated Aloe Vera (as natural as possible) just to soothe and cool the area. I tried tea tree oil the first night and it made my face feel really weird so I stopped. I think the general consensus is that you don't really need anything for after care and your body will do it's business.
