Protect your hands, especially the top of your hands, from sun damage by slathering a good amount of sunscreen on them. “The tops of the hands are especially susceptible to long-term UV damage and risk of skin cancer and premature ageing due to driving,” Michael Kassardjian, a board-certified dermatologist in Los Angeles, told a news portal. Adding, “Before heading out, your regular daily sunscreen can be applied to the back of the hands, most importantly to rub it in well throughout for a good base protection. This base application of sunscreen in the morning will help cover all the areas well before you start your day, but the reapplication is where other recommendations come in for easier use."
