T.P.
I had a common problem with some cracks so severe that they were bleeding and very painful. I've started wearing gloves for washing dishes-latex free and my favorite product is Lansinoh lanolin. It is totally safe as it's used for dry, cracked nipples and it use it for all cuts, dry skin, etc. When my daughters were infants, I would put it on scratches they would get from their fingernails and they would be healed overnight. You might want to wear some kind of glove if you put it on at night as it is pretty goopy.
