Skincare routine

So, I'm 26 and dont really follow any routine am/PM when it comes to my face... I'd like to start to try to figure out products to start applying in the morning after washing as well as at night.

I have more oily skin than I'd like.. I use cetaphil in the morning and night before bed to wash my face but dont apply any creams..

Hit me with what you use!! I need to experiment.

I do get random pimples here and there.. really bad blackheads.. my face breaks out terribly before my period but after is totally clear besides blackheads.
