What kind of care is needed during the winter, when the skin barrier is damaged?

It is really tough whenever winter comes.

My heels cracked really badly, and in severe cases, they even bled.

How should I manage this?

Of course, they say it is good to apply lotion every night before going to bed, but

I realized this wasn't easy.

I would appreciate it if you could share a simple and easy way to solve this.
