Almost two dozen sunscreens in Australia have been recalled, paused or are under review because of concerns over their SPF ratings. Some of them are available in New Zealand or can be bought online. In Australia Ultra Violette Lean Screen SPF 50+ was voluntarily recalled following inconsistencies in its sun protection factor. Tests showed it had SPF results rating anywhere from four to 64. Australia's Therapeutic Goods Administration says the base formula is used in numerous sunscreens and further tests show it is unlikely to have an SPF greater than 21. It's also raised concerns about a testing lab used by a number of sunscreen makers. Consumer NZ senior research and test writer, Belinda Castles spoke to Lisa Owen.
