Sunscreens: Sunblock factors are not all equal
17 July 2008
The sunblock factor on a sunscreen pack may be the same as another product – but it doesn’t mean it offers the same protection.
Officials from America’s drug regulator, the Food and Drug Administration, are concerned that consumers are being misled by manufacturers’ claims. Despite claiming to have similar sunblock factors, sunscreens vary widely in their protection they offer against UVA rays, which can cause wrinkles and skin cancer.
Manufacturers have also started using the term ‘broadspectrum’, but again the term is relatively meaningless and does not give an accurate idea of the protection each product provides.
