Summer pore skincare concerns

Since it's summer, my face gets shiny right after washing up—is it oil? Or sweat?

Even after sweating so much, my pores are still full of sebum.

But I can't just go without applying anything, so...

In the summer, I only apply toner, essence, and moisturizer; even though I sometimes skip the moisturizer, it's still...

Even if I only apply that, it gets shiny after an hour or two.

So naturally, the pores are wide open.

I'm not in my 20s with oily skin; I'm in my 40s and my skin gets dry in the fall and winter, so I don't know why it gets so shiny in the summer.

What products should I use in the summer to keep my pores clean and shine-free?

I'm curious how everyone applies their pore skincare in the summer.
