Your sunscreen may smell nice, feel smooth, and have stellar reviews on Amazon. But a new study warns some of the most popular creams do not meet all the guidelines recommended by the American Academy of Dermatology.
The AAD stipulates that sunscreen meet three basic criteria: protects against UVA and UVB rays, has an SPF above 30, and is water-resistant. However, a study carried out at Chicago's Northwestern University found consumers seem more concerned with cosmetic factors when writing their highly-influential reviews of the product online. And worryingly, 40 per cent of the top rated sunscreens fall short of the AAD's criteria.
