"Which" is the UK consumer watchdog organisation. They have just published a report on sunscreens. The SPF rating refers only to UVB protection and we need broad spectrum which includes UVA. UVA protection is indicated by in the UK by stars - I think 5 is the maximum/ All the same I thought this was interesting and shows how careful one needs to be.
According to which Tesco SPF15 only provided an SPF of 12; Malibu High Protection SPF 15 was only 10.2 and M&S 15 was only 7.5, according to "Which" tests.
In contrast they found that Sainsbury's SPF 15 rated a 20.2 and costs only £3.
Other highly-rated brands included Asda Sun System, Garnier Ambre Solaire Clear Protect, Nivea sun Moisturising Sun Spray, Boots Soltan Moistruing Sun Care Lotion and L'Oreal Solare Expertise Advances Anti-Ageing Sun Protection Lotion.
Tesco and M&S defended their products, saying they were tested to high standards.

We can get prescription sunblocks on NHS if prescribed by specialist. Ask your pharmacy for details - GPs and even specialists usually don't know which are available on Prescription. I get the Australian Sunsense and am very pleased with it- it is invisible. Note that it is probably on the GP's list as SPF50, not SPF60, for some mysterious reason but that doesn't matter.
