A "do not buy" warning has been issued to parents over THREE major suncream brands that won’t properly protect children this summer. A study was carried out to determine the effectiveness of popular suncream brands for protecting your children. Which? examined 15 popular sun creams to verify they met the basic required level of sun protection. The investigation found that Morrisons Moisturising Sun Spray SPF30 did not meet the minimum SPF protection levels. The second suncream on the Which? no-go list is the Ultrasun Family SPF30, available for £22.40 from Boots. The outlet said the product failed a UVA test by not meeting the minimum required level in a first and second test. And Which? claimed the Asda Protect Moisturising Sun Lotion SPF30 High, £2.66, also failed to deliver when tested. Natalie Hitchins, Which?'s head of home products and services, stated: "It's really concerning that widely available sunscreens could be putting families at risk by failing to offer the level of sun protection claimed on the packaging. "While shoppers should avoid buying our Don't Buys, our results prove that there's no need to splash out to keep you and your loved ones safe in the sun as we've found cheap reliable options at Aldi and Lidl ." A representative for Morrisons stated: "We work closely with our supplier and conduct extensive efficacy and safety testing during product development. "As such, all our sun care products are tested to the relevant industry test standards and are not approved for launch until they meet these standards. During development and production all tested variants consistently achieved an SPF of 30. "In direct response to this report from Which? we have retested the SPF against the British and International Standard BS EN ISO 24444:2020 and can confirm the product has achieved an SPF value of 34.5 and can therefore be labelled as SPF 30." "We recently had our Asda Protect Moisturising Sun Lotion SPF 30 High re-tested by a leading external provider using internationally recognised testing methods," Asda said. "These test results confirmed that this product has a sun protection factor of 31.5, and therefore we do not recognise the test results Which? has published. When Which? reviewed this same product in 2022, they awarded it 'Great Value’ at that time and it also passed their SPF test. "The product formulation has not changed since then, so we would question the validity of their test.”
