Most people well versed in the wrinkle-inducing, cancer-causing effects of UV rays are slapping on a lot of sunscreen this summer. But a new study by the Environmental Working Group, a Washington non-profit, could change all that. After investigating the chemicals in almost 800 sunscreens, the study reveals a dangerous chink in the solar armour. 84 Percentage of the 785 sunscreens tested that were found to offer inadequate protection from the sun, while containing chemicals with "significant safety concerns." 1 in 2 Products on the market bearing claims that are considered "unacceptable" or misleading under Health Canada's sunscreen safety standards. Claims such as "all-day protection," "mild as water" and "blocks all harmful rays" are not true, yet are found on bottles. 95 Percentage of girls between the ages of 6 and 8 tested who were found to have oxybenzone, a hormone disrupter absorbed by the skin (found in more than 400 of the sunscreen products), show up in their urine. THE BOTTOM LINE Because they often prevent burns, sunscreens give wearers a false sense of being able to stay in the sun longer than they should. But only 12 per cent of sunscreens with SPF 30 or higher contain ingredients known to protect from UVA radiation (the rays linked to skin damage, aging, immune system problems and skin cancer). The EWG decodes the good from the disastrous in its online database, CosmeticsDatabase.com, but if you want what's best for your health and for the planet, according to the EWG findings, it may be time to ditch the 'block, grab a hat and follow the shade.
