Like every year, OCU He made his own Summer analysis To establish what it is The best sunscreen that is sold in SpainThe field is logic, they did not analyze them absolutely, but it is true that they tracked a wide range of brands, both for sale in supermarkets, and in a pharmacy and a pharmacy. In total, 14 brands with a very wide price range were analyzed. The best thing that with his analysis we see that, as we have recently seen, the sunscreen should not be expensive to better protect.
In fact, the one that was classified as the best sunscreen was Decathlon Sun Cream SPF 30Sold on a large surface of sports products 12.99 euros. There were other defenders Budget With a very good note and quite expensive with a terrible score.
To evaluate various sunscreen creams, four factors were analyzed. First, and with the greatest weight of the note, Protective power of their solar filtersThe field should be said that not all sunscreen creams offer FPS that they promise. Unfortunately, this is what cannot be checked on the label, so the laboratory tests ordered by OCU are very useful. Secondly, Easy to use the productWith many factors in the account. Then yours Environmental impact And finally label. All this is transferred to the assessment from 0 to 100, which in the case of the best sunscreen was 75 years old. No one has reached perfection; But even in this case, 75 indicates Very good quality in all respects.
The best sunscreen measured in the laboratory
OCU trusts the analysis of protective power Independent laboratorieswhich are responsible for the analysis of various products using a test known as Spectroscopy of hybrid diffuse reflection.
This is based on a principle that, when Radiation affects the surfaceThis can be reflected in two ways: Mirror and diffuseThe first field, as its name indicates, refers to what is happening, as in the reflection of the mirror. Something like a ball that jumps on the wall. The second, on the other hand, refers to radiation, which It is scattered in many directions.
With a test used by these laboratories, ultraviolet radiation on the skin of volunteers and a plastic surface affects the skin Photons that are reflected by diffuse measurements are measured. This is done before and after the spread of solar protection. In the case of people, they set themselves 36 mg/cm2 cream on a very small surface, only 2 cm2The field, in addition, is just 15 minutes before the measurement. This does not give time to burn the skin, but in the sunscreen to make it magicField
In plastic, having no risk for anyone, you can measure a large surface from 25 cm2, with a smaller dose, 1.3 mg/cm2In addition, half an hour remained. In both relationships, you can see the amount of radiation, which is absorbed and reflected in the skin or plastic before and after placing cream. Thus, you can measure both FP, which relates to the absorption of UVB radiation and protection against UVA radiation. From OCU they indicate that the difference between some FP and others is not exponential. FPS 30 should absorb 97 % of UVB radiation and 50 % at 98 %. Despite this, it should be checked that in fact To absorb what promises. Or reflects in the case of physical filters.
Neither analysts nor volunteers know which product they use
It is important to note that before performing the tests, OCU covers containers Dark tagsTo the tests are double blind. That is, neither analysts nor volunteers know which product they use. Thus, preferences do not adhere to preferences.
And this is what OCU also asks volunteers
To study the simplicity of using each product and determine what best sunscreen OCU makes a number of questions for volunteers. They are interviewed extension capacity, aroma, touch And other problems associated with ease of use. It also has a large weight in the final class.
Environmental impact, measured at all levels
To measure the effect on the environment, both the composition of the sunscreen and its container are analyzed. There are some ingredients that, as you know, are harmful to the environment, for example, as OxybenzonThe field, however, is not the only thing that is analyzed. It is also studied if the product may contain microplastics in its composition.
As for the container, as the materials by which it was made as their Processing
What is looking at OCU on labels?
Finally, the label is analyzed. To begin with, as it is logical, it is important that all the ingredients of the product of the product are included, as well as who they are Less conflict. None of them should be toxic at the levels included, but it would not be sold. But it is true that not everyone is equally contradictory.
In addition, it is punished that they have Possible misleading messagesFor example, there is no good note for those who note that the product is “dermatologically tested”, since any sunscreen in the market. This is only marketing and can make us believe that the rest of the options are worse. On the other hand, messages such as “hypoallergenic” are often punished, since there is no specific legislation for this term, and there may also be some ingredient, often perfumes subject to allergic reactions. As OCU points out, it gives a false sense of safety.
How is the final class?
The final assessment corresponds to 32.5 % with the measured SPF, 32.5 % with protection against UVA radiation, 20 % to a slight test for use, by 10 % to environmental impact and 5 % of labeling.
The best sunscreen, according to OCU (and other good and bad options)
According to OCU, we have already seen what the best sunscreen. This follows, from 74, Nuxe Sun Haute Protection, with SPF 30The field of sunscreen FPS 50+ is the best new one is Eau Thermale de Avene, With 70.
The product with the worst result is One hundred sun of the children’s sunFrom LIDL with FPS 50. Its assessment is 11, which indicates a very low quality and is suspended in all analyzed factors. However, it should be noted that The best sunscreen Budget It is also Lidl. With 69, which indicates good quality, lotion STO I love my planet FPS 30 This has very good characteristics. Paradoxically, given the name of the product, only free from environmental impact.
Another sunscreen Budget It is very well clogged Sun Med Spray Solar, both FPS and 50+ which are sold in Mercadon for 6.48 and 7.36 euros, respectively.
As for the high solar defenders, we saw that more expensive is not always better. The next worst is valued after the Lidl product is VICHY Cream Unctuosa SPF 50+, With 12.
Everyone protects, of course. The problem is that many do not give what they promise or do not protect enough. That is why this annual analysis of OCU is so important.
