Here is an easy overnight treatment using Vaseline and socks.
After finishing all your activities for the day, wrap up by washing your hands with a gentle soap and drying them off. Then get a dollop of Vaseline and rub it into your hands. Go ahead and take an extra 30 seconds to massage your hands gently. Then simply slip the socks over your hands and go to bed. Wake up the next day to supple, soft hands.
Instead of using socks, you could using fabric gloves, but a clean pair of old socks you don’t use anymore work just fine—and don't require a trip to the store.
Hydration is very important. You need to moisturize your self from inside, too.
