Vaseline intensive care essential healing. Yellow one.
Cheapest in Bodycare and Savers.
I had a lot of problems with dry hands until I discovered it. I had previously discounted using it thinking it would be cheap rubbish. It is light and absorbs within a few minutes. Have to get into the habit of putting a circle the size of a 10p piece on every time you wet and dry your hands, which I admit can be a pain in the arse but you can only get smooth hands with commitment if they are really bad.
Whatever you use, you need a lotion, not a cream and certainly not an ointment. Cream/ointment is too greasy and just sits on top of the skin doing fuck all. Saying that though, it is sometimes good to put a lighter lotion on, let it soak in, then add a small amount of greasier cream on top to keep the moisture in but that's more of a nighttime thing.
Little and often and high in moisture is key.
You can also get some mens cotton sports socks, cut off the toe seam end, cut a little hole for you thumb, slather up before bed with something a bit richer and put the socks up your arms. May sound weird but it keeps more moisture in than cotton gloves, they stay on better and keep the area warm which increases absorption of any lotions and potions. Don't do it with anything with steroids in though, not supposed to cover that up as makes the steroids go into your bloodstream too much (or something like that, don't fully recall).
After years of trouble with dry hands and trying every cream going, I now have hands and nails as smooth as a baby's arse and I am knocking 50.
