Why You Don't Need SPF50 When SPF30 Blocks 97% of UVB Rays

Did you know that there is very little additional protection between an SPF50 and an SPF30. In fact, research shows the difference in coverage is as low as 1%. For this reason, the highest sun protection Snowberry provides is an SPF30 sunscreen. We don’t believe that you should pay for more when it doesn’t do much more.

SPF30 sunscreens block 97% of UVB rays. Beyond SPF30, sunscreens offer little effective additional protection. SPF50 blocks 98% of UVB, which is only 1% more than SPF30, however given the way people typically apply sunscreen (‘slip-slap-slop’), this is a barely measurable difference, and many studies also show that we tend to apply less of a higher SPF, and less often, under the misapprehension that it provides much greater protection. The actual protection achieved through typical misapplication can fall well below that of an SPF15 that has been properly applied (i.e. at least one-third of a teaspoon to the face, regardless of the SPF number; and topped-up every two hours).

That’s why in most countries it’s illegal to sell a so-called SPF100, because it’s meaningless. And in Australia, where it was prohibited to sell even an SPF50 until recently, the Cancer Council has said it will still continue to promote the SPF30.
