PLEASE READ, I would really appreciate any advice..

I've always had generally clear skin mind a few stubborn little skin colored bumps that would sometimes swell and become pimples but nothing super noticeable. In november - january, however, my skin was completely (and I mean COMPLETELY) clear and soft and supple - I had not changed my skincare or diet. I was starting to feel good about not having makeup on....and then in march the bumps began to come back.

Around that same time,  I developed a rash on my cheeks because I tried a new moisturizer in hopes that the bumps would go away. While I had the rash, I stopped my skincare routine and used only Cetaphil cleanser, Jojoba oil, sunscreen and aloe vera gel for about a week and a half in hopes that it would help the irritation. The rash went away but I noticed tiny bumps emerging from my forehead and the ones on my cheeks became more prominent. I didn't think much of it and continued with the skincare I used before.

The bumps spread and spread and spread. Some of them became inflamed acne which left scarring, some of them stayed as the bumps. My derm just said, "thats acne" and tossed me some Azelaic Acid. I've been using it since and although the pimples were no longer as swollen, the bumps seem to be spreading! They're along my hairline, sometimes in my hair, migrating along my eyebrows, on my cheeks, on my nose bridge, on my jaw and all over my forehead. It was not this bad before! I don't think clogged pores could spread like this in a span of a week (since each week it seems to move around on my face!)

I searched up folliculitis and it looks exactly like what I have. I've never had skin this bad before and its making me seriously depressed - I don't feel like eating or looking people in the eye or going out...

My question is, is this folliculitis? It doesn't itch on my face but I noticed the bumps came in clusters and I do have an itchy scalp. Also, I've had these bumps since I was a preteen and I always thought they were Keritosis Pilaris since I have that on my arms and legs, but now that I think about it, the affected areas move around on my face. I have dry, sensitive-ish skin that gets a bit oily under my eyes in the summer only (but thats the least affected area at the moment). I've tried glycolic acid, benzoyl peroxide, salicylic acid and nothing works! If it is folliculitis, could I treat it with tea tree oil or is Nizoral best? Thank you so much, I really really appreciate the help. (also what helps with the scarring )
