re: Does anyone else' s finger skin split in the winter?

If you have eczema there are treatments for that but normally if you have this problem just in winter then it's due to very dry hands. Moisten them often. Those lotions you see for hand moisturizers? Yeah, that stuff. It's best to use as often as needed before your skin cracks.

Someone suggested warm salty water and that probably will help, plus it'll be safe with existing cracks. Real saline solution is probably best. But true moisturizer will last longer.

You might also consider picking up a humidifier for the bedroom.
