How do you exfoliate your skin?

Strangely, my skin has always had to be pushed aside, except for when I briefly studied abroad in Australia in my 30s.

Even if I shower every day, my skin becomes dry after a few days and becomes flaky when it gets wet.

I know that pushing the time is bad for your skin, but I keep pushing it, so I have no choice but to push it.

I applied body lotion diligently and scrubbed, but it didn't seem to have much effect.

Do you know a good way to manage dead skin cells without rubbing them?
