Is it possible to change one's skin type?

I definitely thought I had oily skin in the past, but lately it doesn't seem like that is the case.
It seems like the oil has decreased, but instead, I feel more dryness.
I'm confused whether my skin type has changed or if it's simply a matter of my condition.
I became curious if it is true that your skin type changes as you get older.
So, products that used to fit well feel a bit off these days.
I'm wondering if it's time to get my skin type re-diagnosed.
I became worried about whether it is okay to keep using the product based on the same type.
How should I approach skincare when I notice changes in my skin type?
