Why isn't inner dryness going away even if I apply moisturizer diligently?

It looks a bit shiny on the surface, so I thought I had oily skin, but strangely, my skin feels really tight deep down just a short while after washing my face. I'm applying a generous amount of cream, but it feels like it dries out again after a while, which is frustrating.

It’s especially stressful because when I wear makeup, the sides of my nose and around my mouth start to flake off by the afternoon. I think I might have typical dehydrated oily skin—oily on the surface but dry underneath—but I’m not sure what routine to follow to manage it lol.

I'm getting even more confused because some people say layering toner multiple times is good, while others say ampoules are more important. If anyone has successfully improved their severe inner dryness, please share your skincare routine or product recommendations!
