Remember years ago, when you'd walk into a pharmacy only to be greeted by a cut out of a young female in a bikini boasting that deep, dark, tropical tan? I recall all those suntan lotions and creams, and how little jars of cocoa butter would melt at the beach and make everything smell like coconut.

Many still sport a tan, but now we've learned the harmful effects of too much sun without protection. It's a good idea to pack and apply sunscreen to your skin that's exposed to the sun. And make sure you apply sunscreen on the kids which holds up even in the water. During the "Frog Days of Summer", it's import to have the proper SPF sunscreen.

According to medicinenet.com , here's what meant by SPF:

"SPF, an abbreviation for sun-protection factor, is a number such as 15, 30, or 50 that indicates the degree of sunburn protection provided by sunscreens. SPF is related to the total amount of sun exposure rather than simply the length of sun exposure.

Further, sunscreen must be reapplied every two hours when staying outdoors for a prolonged period of time. Sunscreen should also be applied at least 30 minutes before going outdoors.

People with sensitive skin who burn quickly and must spend a lot of time outdoors should always apply a sunscreen with an SPF of 30 or more."
