Please recommend products to care for dry skin.

My skin tends to be dry, so I struggle with skincare every year from around this time until about May of next year.

I've heard that drinking plenty of water is good, so even though I drink it frequently, it doesn't seem to have any effect at all.

Even if I apply a generous amount of body lotion after showering, dead skin cells start to peel on my calves after about an hour or two.

The cracking on my heels seems to be getting worse, especially.

I have tried heel care, but the effect only lasts for a short time during the procedure.

I'm wondering if there is a way to provide care at a fundamental level.
