How to treat dry, peeling, cracked, bleeding skin?

Hi doctor,

For about two years, I have had constant problems with the skin on my hands. There are spots on my hands where my skin becomes extremely dry, to the point where it peels and sometimes even cracks and bleeds. However, it regenerates quite quickly, with even deeper wounds healing within three to five days. I have consulted several dermatologists, and here is what I have been able to confirm so far:

1. It is not a fungal or bacterial infection, but it may be related to a blood vessel problem.
2. Smoking tobacco seems to worsen the symptoms (causing more peeling and cracking).
3. The problem occurs only in a few areas on my hands, mainly on my index fingers and right thumb (please see the attached photo).
4. A cream containing urea seems to be the most effective.
5. Barrier creams have not helped.
6. My diet does not seem to have a noticeable impact on my condition.
7. Supplementation with silica, Q10, and collagen has not been effective.

Sometimes, when my condition improves and there is no dried or peeled skin on my hands, small red dots become visible just under the skin. One of the doctors mentioned that they look like burst blood vessels. These are visible in one of the attached photos.

Please advise.

Thank you.
