Both hand and feet are important parts and need care. As they are displayed so for good grooming one need to have neat and beautiful hand and feet. I apply lubricating cream after bath or any washing chore. Every night before bed time. I use cream and massage my hands and feet for few minutes.
After every ten or fifteen days I do Manicure and pedicure at home either using two tablespoons of salt or abit of shampoo with hydrogen peroxide and liquid ammonia in warm water. Dip my hands for few minutes and rub pumice stone to remove all dead skin. Then push back the cuticles and apply cream and massage
You can even try some exercise for hands and feet.
