Top sunscreens fail protection tests

Piz Buin Ultra Light Dry Touch Sun Fluid SPF30 150ml; Malibu Protective Lotion SPF30 200ml; and Hawaiian Tropic Satin Protection Ultra Radiance Sun Lotion SPF30 200ml; all had results lower than sun protection factor 25, despite claiming an SPF of 30, consumer group Which? said.
It has branded the creams as “don’t buys” in its investigation, which used British Standard tests to check 15 products with an SPF of 30. A second round of testing produced the same results, it said.
