Ever wonder what the SPF really means in sunscreen. Is there really a difference between SPF30 and SPF 75? Let's start at the beginning. The suns ray are made up of UVA and UVB rays, but the UVB rays are the ones that cause the painful burn and SPF only refers to the protection you gain from UVB only. The sun protection factor (SPF) well give you an idea of how long it would take you to burn on a hot sunny day. If you usually burn within 10 minutes of being out in the sun, you can times that number by the SPF and that will roughly give you the time in minutes of how long it will now take you to burn. However, this number will drastically change if you are in the water or have been sweating or have applied some mosquito repellent. The general rule is to reapply sunscreen every 2-3 hours. Now, is there really a difference between SPF 30 and SPF 75....NOT REALLY. After about SPF 35 the time in minutes that you gain from a burn is nominal. So to sum up buy at least SPF 30 sunscreen and reapply, reapply, and REAPPLY.
