Specialty Sunscreens
There are sunscreens developed for specific parts of the body. Many lip balms come with extra SPF protection, such as ChapStick's Ultra 30 sun-care lip balm. This protects your lips from sun damage and drying while being safe to ingest (and more appealing to taste if you accidentally lick it off).
The scalp is an often neglected part of the body which is easily sunburned and hard to relieve once the damage is done. Rubbing cream into your hair isn't very appealing, so Banana Boat developed a great Sport Performance Sunscreen Body & Scalp Spray that mists onto your scalp. Of course, a hat is recommended to protect both your scalp and your face.
Young children may squirm at the application of sunscreen, so many kids' sunscreens come in handy spray formulas that are quick to apply and require no rubbing. Many are tear-free and no-drip so when your little ones get wet there is no stinging or red eyes. Baby sunblock is much the same, with milder formulas designed for younger sensitive skin.
