The Australian sun is fierce. On a lightly overcast day 80% of the searing UV light can still get through – more than enough to cause skin damage and, potentially, melanoma. We are way more sunsmart than we used to be, and deep tans are fairly rare. But a freckle-free face is no guarantee that all is well, as Carrie Bickmore discovered when she got a scan from the UV Photobus touring the country. The bus is a clever marketing move by sunscreen manufacturer Sunsense, providing a free, um, portrait to anyone who wants one (if you can get seen – only 2 of the 21 days are reserved for Sydney and Melbourne’s 8.7 million inhabitants!) 80% of damage is done before the age of 18, and the UV scan has changed Carrie’s attitude to protecting her 5-yo son. “I think he's annoyed with me, but now every day we have to put sunscreen on”.
