Several year's ago I developed what seems to be the same type of problem you have on both of my hands. I ignored it and it got out of control -- eventually the flaking resulted in cracking and bleeding. The doc gave me a cream with cortisone -- cleared up. I would try to do something before it got any worse; use a rich hand cream maybe with aloe and if you have an old pair of cotton gloves wear them to bed after slathering your hands with cream. (You can buy "night time" gloves at the drugstore). Good luck.
