What's the whole deal on popping zits?

i've had zits since 5th grade (im going into 10th) and i've learned quite a bit on taking care of skin. like everything on what to eat and what kinds of regimins and stuff but the thing is, i have like a compulsive picking disorder that i'm trying to get over. i've been doing pretty well so far..





but i just read online that your SUPPOSED to pop the full ones, like the ones where the head is completely white, and you just put a cotton ball with salty water and then slowly take it out which works great.. no irritations or anything.





but my question is... what should you put on the zit once you've popped it properly? i wouldnt think any sort of zit creme.. and i tried neosporin but it just broke me out more...





heres what i've read so far.. aloe vera, tea tree gel, and honey. those are just some of the things..





thats what i have at least, but im not gonna put all three on it... what should i put on it? also what do i put on red marks that are under the skin? thank you!!What's the whole deal on popping zits?
What works for me is olay toner(blue bottle) when i have a popped pimple this drys it out and goes away in 1 day(depending size)


p.s it burns for a second^o^
