I don't have any blemishes, but what could be the reason my skin doesn't look good?

It’s not like I have severe acne or a lot of blemishes, but strangely, my skin doesn’t look good.

When viewed up close, the skin texture is rough and the overall appearance is dull.

Even when I apply makeup, it doesn't go on smoothly and looks a bit heavy. In cases like this, I'm confused whether I'm lacking moisture or if I need to exfoliate. For those of you with minimal breakouts but poor skin condition, what kind of skincare routine has been helpful?
