Best way to heal broken dry skin on hands and prevent infection to myself and others?

Creams, ointments. Broken or fissured skin on the hands are best treated with creams not lotions. Eucerin cream is good. Aquaphor is another good one. Best to apply at night and the cover with gloves til morning. When hands are in water or chemicals, wear gloves. Topical steroids by prescription also very helpful. There is no cure. Avoid things that make it worse. Above topicals are good to use during day.
