What is causing the skin around my thumb and middle finger to be dry and cracking?

For weeks now the skin at the tips of my thump and middle finger have been extremely dry and cracking. No manner of skin lotion I have tried works. Also when I finish taking a shower it dries out instantly.|||hmmm maybe the weather or a skin condition but if i were u i%26#039;d get the best selling cream E45 its for rashes dry skin and exma u can find it in ur local pharmacy.
