On her blog, socialite and style icon Oliva Palermo recommends applying sunscreen to your whole body before getting dressed even if you're not going to the beach. While that may seem extreme if you don't live in L.A. and don't plan on wearing short-shorts and tank top to run your errands, protecting your skin from harmful UV rays—no matter how you do it—is key.

• Top Of The Ears

  Just because you're wearing a sun hat, it doesn't mean you should skip applying sunscreen on your ears. Dermatologist Dr. Julia Carroll says most people think they're being protected, but ear burns are quite common.

• Behind Your Neck

  Yes, you could've just forget to put on sunscreen behind your neck, but often, people with long hair think they're being protected, Carroll says.

• Fingernails

  This is a rare occasion, but some people -- especially if they're on certain medications or antibiotics -- can end up with yellow-toned nails after being exposed to the sun.

• Tops Of Feet

  Sometimes we're so busy applying sunscreen on our legs, we often forget about the top of our feet.

• Around Your Arm Holes

  You may want to be careful with this one. If you're going on vacation or spending the day at the beach, you should consider applying sunscreen near your arm and neck holes to avoid sunburns. Even though your skin is technically covered, our body's movements could expose our skin.

• Clothing With Holes

  No, we're not talking about clothing that is worn and torn overtime -- even though you still need sunscreen if you wear any of those. Lace, crochet and any other type of clothing with intentional openings can leave burn marks on your skin.

• The Scalp

  Our hairlines can also get burnt. Carroll recommends applying a thin layer of sunscreen -- yes, onto our heads -- to avoid redness and itchiness.

• "The Corona Effect"

  These cases are rare, but Carroll has seen them in her office. Most of us can agree that nothing beats the summer heat like a glass of cold beer. But Carroll says, in rare occasions, when people are squeezing limes, they could squirt acid onto their skin and cause a reaction with the sun. She's also seen people with dripping marks on legs and hands -- especially on waitresses.

• Crossing Legs

  Carroll says you should reapply sunscreen every two hours, especially if you're sweating or getting wet. If you're sitting or lounging outside, most of us cross our legs, which can rub off pre-applied sunscreen.

• Eyelids

  Eyelids are another painful and common area. Just because our eyes are open, it doesn't necessarily mean they're protected. However, if you're looking for the right sunscreen for your eyes, make sure you choose a light-weight cream for the face.
