Fingers dry cracked need cure

Recommendations are greatly appreciated!

Couple of years ago I worked at a steel plant using different chemicals to cut steel , I have a feeling this could be why my fingers are like this!

I constantly use okeefes hand cream as well as other lotions and no matter what it comes back I have no idea what to do it’s only on my fingers the rest of my hands are ok.

Also I don’t have any insurance atm so that’s why I’m posting here to see if anyone can lead me in the right direction

I posted a pic of my pinky but it’s a lot worse on both of my thumbs
