Whoa, whoa, whoa -- if you apply sunscreen at all, then surely the hands must be protected, right? Well, your palms and fingers may have the remnants of sunscreen, but people may not remember to apply sunscreen to the tops of their hands. If you're headed out for the golf course or garden, you may wear gloves at first but eventually remove them, leaving your hands exposed while the rest of your body is sunscreen-protected. Hands already spend way more time in the sun than other body parts. Not only does this constant exposure put a person at risk for developing skin cancer, your hands will start to look unsightly. The presence and appearance of age spots are exacerbated by the sun, and UV rays can damage the fingernails.
