Please help me! life or death LOL?

I have been really lazy about my skin lately and because of that I have been breaking out! so now I am trying to get back in the process of taking care of my skin and keeping it healthy and blackhead/pimply free! (:
but i was wondering if products that help your skin have a expiration date?

also can i use 3 products at once?
i am currently using
Neutrogena Daily Scrub (for my pimples)
Aveeno Skin Brightening Daily Scrub (to even and tone texture)
Clean & Clear Blackhead Clearing Scrub (for blackheads)
