DESPERATE for Skincare Advice!! (Pics)

So I’ve had bad acne since I started puberty and now I’m 20 and it hasn’t changed. My skin is shiny in these pictures because I have coconut oil on my face. I’ve noticed that this past week since I started using coconut oil and Tea Tree Oil Creme at night, I haven’t been breaking out so much, but that’s not exactly my problem..

What I’m trying to fix:

-DRYNESS- Very flaky, almost scaly dry skin (Notice my nose where you can see scaliness along with a hundred black heads). No amount of exfoliation helps get rid of the dead skin.! But somehow I also have a naturally greasy complexion. Also notice my cheek to the right of my nose, my pores are huge and extremely visible.

-RED SKIN & SCARS- On my cheek pic, there is currently only 2 pimples, and the rest is blemishes/scarring from a breakout I had two Easter’s ago. They’re always red and I’m not sure how to properly heal them, though I do realize it might be too late..

Keep in mind I don’t have a lot of money to spend on products, probably why my skin is so awful. My skin is one of my biggest insecurities.. I can’t properly apply makeup because it fuses to the dryness and looks super caked on as the day goes on, so I can’t reapply my makeup because it already looks 10 times worse after wearing it a few hours
