Skin help

[gracilejenn]

I just turned 40 and I don't know if it's related, but my skin has started to get all flaky on my face. It's concentrated mostly around my chin. I've been using an Aveeno scrub (Daily Detoxifying, I think. It's in a yellow tube.) It helps a little. Is there another scrub that works better? Should I change moisturizers? I use Cerave. Should I switch to a liquid foundation? I feel like the Lancome powder one I use accentuates the flakes.

I'd appreciate any help I can get. These flakes are driving me crazy, lol.
