Dry Skin Dehydrated with large pores and acne after applying makeup

So my skin feels dry/dehydrated a lot, but after applying makeup i’ve found i get shiny and just.. “ew” . I don’t really have a good skin care routine as I don’t know where to start since my skin changes often.

But i’m really looking for a daily routine, but don’t know where to start.

What products would you recommend for someone with dehydrated skin, but still has large pores and some acne issues?

& besides skin care, what’s a good foundation you’d recommend?

I thought about trying the born this way foundation but have seen mixed reviews.
