For many users, cosmetic factors are more important than the sun protection factor
Especially in summer it is likely that your skin will be exposed to a lot of sunlight. Of course, it is important that you use the right sun protection. But researchers have now found that, unfortunately, most consumers do not always choose the most effective sunscreens. Odor and rapid absorption into the skin are often more important than the sun protection factor. The experts tested the funds that were rated best by consumers on Amazon.
Many consumers swear by the effectiveness of certain sunscreens. It is quite a different matter when doctors check sunscreen products for their effectiveness. Scientists from the Northwestern University Feinberg School of Medicine in Chicago have now found that a top rating from consumers is not always true. Many people used a sunscreen that does not meet the guidelines of the American Academy of Dermatology (AAD). The doctors published the results of their study in the journal "JAMA Dermatology".
Many people buy products with an insufficient sun protection factor
Scientists are now investigating products for sun protection that have been bought and rated particularly often on Amazon. The experts tested whether these protective agents really guaranteed the best protection. Products with the highest ratings as well as products with the highest number of ratings were examined. It was noticed that many people buy products with insufficient protection, the authors say.
Experts checked 65 sunscreens
First, the researchers checked whether the 65 sunscreens tested met all of the recommended guidelines. These guidelines include a sun protection factor of at least 30 for UVA and UVB light. The products should also be water and sweat proof. The research showed that around 40 percent of the products did not meet the AAD criteria. The majority of these products were not resistant to water or sweat, doctors add.
Stiftung Warentest: cheapest sunscreen is the best
A recent investigation in this country had shown that good sun protection does not always have to be expensive. When evaluating sunscreen products, Stiftung Warentest came to the conclusion that the cheapest product is the best. So it is quite possible to optimally protect yourself with cheap sunscreens.
Cosmetic applicability must always be balanced with adequate sun protection
Many of the positive reviews were based on the so-called cosmetic elegance of the product. Factors such as the smell or color of the sunscreen were often included as positive points in the evaluation, the scientists say. Dermatologists need better advice to their patients about which products they should ideally use. The different cosmetic applicability must always be accompanied by adequate sun protection, the authors explain.
For a lot of people, cosmetic properties are the most important
The results weren't really surprising because many consumers don't focus on sunscreen performance. There are still a lot of people for whom cosmetic properties are more important, the doctors explain. Of course, it is also important that consumers like their sun protection. Because if the smell is pleasant, for example, they are more willing to apply the protection.
Not everyone needs waterproof products
Some of the most popular products can be applied on a daily basis, for example before people go to work. In this case, waterproof formulas can even be dispensed with, the experts say. There is no need to apply waterproof products if the consumer has not planned any outdoor sporting activities or if he does not come into contact with water. Only the sun protection should be decisive for these consumers, add the cars. (as)
