Winter Hand Care

I have a question about hand care in winter.
Every winter, my hands become dry and rough, and sometimes even crack and sting. I try to apply moisturizer frequently, but because I wash my hands so often, the effects don't last long. Especially after being exposed to cold wind or going outside, the backs of my hands become red and tight, which is especially uncomfortable. I'd like to know any home care methods or moisturizing tips that are especially helpful in the winter. I'd also like to know if professional care or treatments are helpful. Please advise me on how to gently improve the condition of my hands.
