Older adults with psoriasis

My mother is 79 years old.

My whole body has become extremely dry suddenly.

You are so itchy.

Even after bathing, white powder like dandruff keeps falling from my body.

The floorboard is so worn that you can see powder when you gently touch it with your hand.

How often should elderly people take a bath?

I'm not sure if it's good to do it frequently or not;;;

My mom has had a habit of scrubbing her skin very vigorously since she was young;;;

You are feeling unwell right now, so I can't push you that hard...

Can you recommend a cream to apply to the body when it is dry and itchy?

My elderly mother is getting sicker day by day, and there's nothing I can do to help.

I wish you could stay by my side longer;;;;;;;;;;

You cannot stop the passing of time.
