Cracking fingertips...???

I work as a server and have very Dry skin (eczema). I am 29, So i have the eczema under control, but it is showing up on my fingertips now that I have been a server at the Red Lob for the last month or so. I clipped my fingernails tight but not beyond the quick, then the ridge line split parallel to my fingernail. They dry due to constant washing on a very busy shift and I rarely get a day off...now they are splitting perpendicular to my nails...and they hurt when I touch anything.

Is there a way to harden the Skin around your fingernails to make it impervious to these types of problems? Calling all nail specialists and manicurists...I need your help? Is there a product I can buy or a procedure I can go through to stop this occurence...heck it hurts to type this question. (I just got salt juice in the crack from a Wendy's fry - it Burns and burns like fire just beneath the surface of what feels like my entire fingertip. Help, Please...I don't want to quit over this!
Had the same problem. Im not a manicurist but try putting petroleum jelly on your hands before you go to sleep or if possible in between shifts. Its cheap, affordable, and effective as the leading brand.

During work you can use a lotion that is not as greasy a petroleum jelly. Eucerin works well (but costs more vs petroleum jelly), and is better absorbed.

Also avoid hot water handwashes and pat dry your hands (dont rub) with a paper towel.
