Is there a way to prevent dead skin cells from forming during the winter?

My husband tends to have a high body temperature, and perhaps because he has sensitive skin, when he scratches because of the itching...

Sometimes I get rashes.

On top of that, spring, summer, and autumn are fine, but my skin gets really flaky, especially in winter.

I also tend to have dry skin, so dead skin cells on my body are noticeable in the winter.

It seems like I get them more often as I get older...

So I take baths often in the winter.

But I think exfoliating frequently with a bath would be worse for dry skin.

I tell them not to do it too often, but it's hard for them to.

I apply body lotion after bathing, but it doesn't prevent dead skin cells from forming.

Does showering frequently actually cause dead skin cells to build up more easily?
