Living in Australia means most of us grow up in the sun and from an early age we’re educated on how to be sun safe. From the good old Slip, Slop, Slap message right through to the consequences of too much sun exposure and the signs of sun damage to look out for – we’d consider ourselves an educated bunch.

But when it comes to sunscreen and an SPF rating, how educated are we really? In many cases, we look at the numbers and automatically assume that ‘bigger is better,’ but it’s a little more complex than that.
