I'm so stressed because my dead skin cells stand out whenever I wear makeup.

My skin is usually fine, but I'm worried because dead skin cells around my nose and cheeks suddenly become noticeable whenever I wear makeup. Even though I think I apply a thorough base, my foundation feels cakey and makes my skin look even messier. It gets especially bad on dry days, to the point where there are days when I don't want to wear makeup at all. I've tried scrubbing and applying plenty of moisturizer, but it doesn't seem to be improving much. If you happen to have any tips for achieving a smooth base without highlighting dead skin cells, or any effective skincare products or routines, please share them!
