The combination of cold, dry winter air, having our heater on and frequent hand-washing and sanitizer use has really wreaked havoc on my hands. skin is dry/cracked and sore. what sort of ingredients should i look for in a lotion to help them heal?

This problem is very common during the winter because of using warmer water besides more soap and alcohol we use during the pandemic. You have to use moisturizer after each handwashing and at night before sleep and try to use cold water for washing if tolerable. Lubriderm is one of the trusted moisturizer you can use. Use Dove soap if available and avoid alcohol if you already wash hands with soap
