I have a similar problem. Hope you can get these products in US:
The best one to use is Derma Drate - it was made by DermaTech Laboritories here, but the company was bought out by a multinational in about 2008 - so you may be able to get it. Their other range of products is Dermaveen which is based on oatmeal. They are extremely good products for people with dry skin. Lucas' Paw Paw ointment and Vaseline are good moisturisers, but very greasy. Hope you have some luck.

I used to have cracked, bleeding hands when I worked retail and had to process freight, (many boxes) and then the clothing, very harsh on hands. The pharmacist instructed me to get Acid Mantle which came in a metal green tube, like a small tooth paste tube size. It always worked like a charm but I don't think that they make it any more, or it is hard to find. In later years, I would have to ask any pharmacist if they had it. I still have the remains of my last tube which I won't part with and I have been retired now for 14 yrs.

I was given Vanicream by my dermatologist for dry skin/hands/feet. It is available OTC but not easy to find. Big bottle with a pump which I like. No odors, colors, lanolin. Very pure. Absorbs very quickly into skin so I don't feel like a greased monkey if I use it during the day. Far better than anything else I've ever used. I've had cracked fingertips before and it's enough to make you cry. Good luck.

One of the ladies at my quilting group swears by Vicks Vapor Rub on her dry cracked fingers.
Next time I get them... I'm going to try it!

When I lived in Alaska - I learned to use crisco the white shortening. It does work. Use it for baking and then don't throw the can you use the rest for your hands, feet

Surgeon's Secret is a good one to use and it doesn't wash off quickly. My husband has his hands in water a lot and this works well for him.

This may sound silly to cure dry hands but it really works. You need to moisturize from the inside and drink a lot of water during the day. Works for me.

There is a product in a jar, the night formula of NoCrack, its a white jar with red writing, but there is a smell of Arnica. Lantiseptic was mentioned and that or Calmoseptine would work for overnight, but both have odor, and some people are allergic to the lanolin in Lantiseptic.
For my diabetic patients and in the winter I use Elta. It's very greasy when first applied, but you could probably return to quilting within 20 minutes of applying.
Once healed, the Advanced care Vaseline lotion works well too.

Gold Bond! Wonderful hand and foot creams!

Olive Oil. Rub it on your hands, put on your med exam gloves, and put a hot towel around them. About 15 min. a day will help a lot. If you use it at night, just a little bit of oil, cotton gloves. Olive oil is amazing stuff!
