I also get cracked hands and fingertips from working in the winter, I often have to take my hands out of my mitts to handle fish caught by ice fishing. I wear thin polypro gloves inside my Military Artic Snowmobile Mitts but sometimes I have to work bare-handed to increase dexterity.

If my hands are cracked I have had good luck using Polysporin on them. I also put Polysporin on my firestarter cotton balls, I think it makes them extra multiuse (stole this idea for someone else on this forum). I will try out the liquid bandage for use on split fingertips, they are a painful nuisance. I also daily use Blistex Medicated Lip Balm, or Medicated Lip Ointment if they are already chapped.

This winter I bought some Dermatone Skin Protector to try on my hands and face. I think I will also pickup some Dermatone Lip Protector because it has a higher SPF rating.

I will post how it works out,

Mike
