Beware of day creams with UV filters, we will explain why it is better not to use them

Day creams with UV filters can give a false sense of security about sun protection. In fact, they have a low or medium SPF and are not applied consistently throughout the day

Day creams that not only hydrate, act against aging or have other beneficial properties for the skin, but also have a UV filter, i.e. protection from the sun’s rays, have become quite common on the market.

But is it really so? The answer is: only partially. In general, in reality, these creams are only applied once a day and their protective effectiveness is low. They don’t have to so absolutely be considered an alternative to real sunscreens and may even pose a risk.

The problem is exactly there false security that the use of these creams can give consumers, perhaps believing that they are protected throughout the day by using these products.

As we have already said, these day creams are equipped with a generally low SPF (15-20), although there are also preparations with SPF30 (which should still be considered as medium protection). Then there is the problem that in reality, when you are in the sun or after sweating, you need to reapply the sunscreen, but in the case of the moisturizer, after applying it in the morning, we hardly bother to apply it again. as protection.

Therefore, it would be better to avoid them instead of using a full-fledged sunscreen. As the magazine’s experts write 60 million consumers:

Since ultraviolet (UV) rays are the most common cause of skin aging, this idea seems laudable, and many consumers apply SPF every morning. However, this gesture turns out to be unnecessary and even totally counterproductive! How to reduce this risk? Apply sunscreen every two hours. Something that is never done with a moisturizer that is applied only once in the morning: the skin is no longer protected against UV radiation and free radicals (ROS) can form in the epidermis.

French experts also point out that ROS formation has not been studied in all UV filters, so some would not be safe in this sense:

So far, benzophenones such as oxybenzone and dioxybenzone have been identified; cinnamates such as octylmethoxycinnamate (OMC); PABA and its derivatives such as padimate O; and octocrylene.

Therefore, it is good to always first read the labels of the cosmetics we buy and avoid products that contain these substances.

Another problem with day creams with SPF is that for the UV filter to have any effectiveness, it would be necessary to apply a high dose of day cream (2 mg per square centimeter of skin), which would cause discomfort or even shine on the skin and would be unsuitable for a moisturizer.

Better than use a good Inci moisturizer in the morning and use sunscreen during the day. If you don’t know which one to choose, check out the latest tests on this topic:
