Is a Higher SPF Really Necessary?

I was inspired to write this blog because a friend of mine was so insistent that she uses nothing less than SPF 60 whenever she is in the sun.  I had always believed that once you got up higher than SPF 15 that the differences were really negligible and it wasn’t worth the extra money.

So, if you are traveling to the Cook Islands, the Greek Islands, or any other hot spot, read on to discover the truth as to whether a higher SPF is really necessary.

I started my research at the American Academy of Dermatology.  First of all, it is important to understand the UV Index.  The UV (ultraviolet) index forecasts the amount of sun damaging UV radiation reaching the earth’s surface when the sun is highest in the sky.  However, it does not account for reflective surfaces.  The higher the UV Index, the more protection you need.

SPF (sun protection factor) represents how much longer a person wearing sunscreen can stay in the sun before beginning to burn.  For example, SPF 8 means that someone can stay in the sun 8 times longer without burning than if she or he was wearing sunscreen.  SPF usually ranges from 2 to 60. 

The big question – Is SPF Higher Than 15 Really Necessary? The American Academy of Dermatology and the Sun Safety Alliance, recommend that every individual use a broad spectrum sunscreen all year with an SPF of at least 15.  For children, both groups suggest sunscreen products with an SPF of at least 30.  They also suggest lip balm with SPF, wide brimmed hats and sunglasses to protect lips, head and eyes. 

A higher SPF sunscreen is recommended for those that are fair skinned, sunburn easily or are spending many hours outdoors (ex. those that work outside).  The Academy also reminds people that all sunscreens, regardless of SPF, need to be reapplied, so always follow the guidelines provided on the bottle.

A hot vacation is always a welcome change especially if you come from a cold or damp climate.  It is vitally important to choose a sunscreen with an SPF of at least 15 and to reapply as directed.  You don’t want to get a nasty burn that makes your vacation uncomfortable and puts you at higher risk for getting skin cancer down the road!
