Suggest Treatment For Cracks And Air Bubbles Under The Skin On Fingertips

I do a lot of kayaking. Everytime I come back from a trip, the skin on my fingertips and thumbs go hard and start cracking and it feels like there are air bubbles under the skin. Over the course of the next week this skin peels off and then is red and sore for a couple of weeks before it fully recovers. I have also noticed that the skin on my finger tips does not go wrinkly when immersed in water.
