Red spots appear every winter

I usually take care of my hands and apply hand cream to the back of my hands.

I apply it well, but in winter, it gets on the back of my hands and wrists.

Spots appear like this

So, I got a prescription from the hospital I go to for diabetes treatment and applied the ointment.

It doesn't work

Should I go to a dermatologist and get treatment?

But I have a bad memory from the dermatologist. One time, I got burned by an iron and went there. I was left with a big scar because they didn't treat me well, as if they were a plastic surgery clinic.

I would also like to ask you all for some good information.
