[Routine Help] I don’t know what I’m doing please help

I don’t know a thing about skin care but I do know I need to make some improvements to my skincare “routine.” I dont really have a routine at all I just use Cereve SA cleanser when I shower and Cereve moisturizer after and that’s it. I’m hoping someone can give me some routine suggestions to help my skin look better. I need something very minimal, I have a hard time maintaining systems that are a ton of steps. I’ve never had a real struggle with acne but I’ve listed some things I feel like I’ve been having some issues with. \- Skin feels VERY exposed and oily after washing especially if I forget my moisturizer \- My face tends to be dry. I find myself thinking my face looks dry and flaky in the middle of the day. \- I get a lot of black heads on my cheeks. \- The pores across the middle part of my face and my nose look VERY open and like they need cleaned out. That area reminds me of a strawberry. \- My under eye area tends to be dark and more purple than the rest of my face.
