White dead skin cells... are popping up as it gets colder.

Hello. My hands are usually fine, but I notice dead skin cells when I'm tired or my skin is dry. Even though I drink plenty of water, if I still see dead skin, should I scrub it off? Or should I just use body lotion to replenish moisture? It's usually okay, but this happens when I'm tired. It has gotten worse as the weather has gotten colder, so I'm posting this to share my concerns.
