UV Protection in Day Creams: Really a Good Solution?

UV rays damage the skin and cause it to age. This is well known and that is why there are more and more day creams that also have a sun protection factor (SPF). What sounds like a good idea also has disadvantages. Here's what to look out for.


Is the UV protection really sufficient?

It is true that UV rays age skin by creating free radicals. A day cream with SPF reduces this source of stress. It protects against pigment spots and wrinkles.

However, there is never 100 percent protection, as not all UV rays can be blocked. Especially the UVA rays, which cause the creeping long-term damage, are difficult to block.

If a day cream with a sun protection factor is also to have an anti-aging effect, the UVA protection must be high. This is the best way to counteract skin aging and wrinkling. Many day creams do not have the UVA seal, which shows better UVA protection.

Our tip for UVA protection:

Make sure that the UVA seal can be found on the packaging. The seal certifies that the product has UVA protection of at least 1/3 of the UVB protection. In general, the higher the UVA protection, the better. If in doubt, ask your manufacturer.

Every day care product with SPF should have this UVA seal

A day cream with SPF is different ...

UV filters are used in creams to protect against the sun. For adequate protection, especially against UVA rays, a significant amount of it is required. For a sun protection factor of 30 with a UVA seal, UV filters can make up 20% of the cream. That is a lot and leaves less room for other active ingredients that are good for the skin.

Most compatible UV filters are fat-soluble and feel greasy on the skin. Therefore, fewer of the good oils that supply the skin with important lipids can be used in the cream.

In natural cosmetics, only mineral UV filters in the form of zinc oxide or titanium dioxide are used. These change the texture and feel of the skin. In addition, these filters can have a drying effect. This can be beneficial for blemished skin or acne. Of course, this only applies if the formulation does not rely on an excessive amount of oils.

UV filters need a different cream base

A high level of UV protection cannot be combined with a skin-like cream base (e.g. with the natural active ingredient phosphatidylcholine, the main component of our cells). That is why a day care product with SPF can never develop the same effect as a very good cream with only skin-identical ingredients. However, good care properties are still possible.

Day care products with a high SPF can also contain good anti-aging ingredients such as hyaluronic acid or vitamin C, which also protect your skin from the sun. Ceramides, the basic building blocks of our skin, are particularly useful in a face cream with sun protection. Ceramides provide more moisture and thus improve the self-protection time. They also ensure that hyaluronic acid works even better.

Good UV filters and bad UV filters

Not all UV filters are also compatible. UV filters should not have any hormonal effects, be photostable and have no allergenic potential. Whether nanoparticles are questionable is hotly debated. We do not recommend using it.
In this article you will find out which UV filters we can recommend and which UV filters we consider questionable.

Protect the skin from free radicals

UV rays are primarily harmful because they produce free radicals in the skin. These aggressive molecules destroy important building blocks of healthy skin. The result: premature aging of the skin. With an SPF in the day cream, the problem can only be reduced, but not eliminated.

Free radicals are also constantly formed in the body regardless of the sun. The danger threatens not only from outside, but also from within. In addition to UV filters, the supply of antioxidants is therefore important.

Antioxidants neutralize free radicals and help our organism to stay healthy longer. Anti-wrinkle care should therefore always contain antioxidants.

The best-known antioxidants are vitamin C, vitamin A and vitamin E. However, there are also particularly effective antioxidants from nature. Astaxanthin is considered to be the most powerful antioxidant in the world. That's why we use it in our day care with SPF 30, the Dayshade Cream. The Dayshade Fluid, our red sun protection oil with SPF 50, also contains astaxanthin.

The natural self-protection of our skin

The skin has its own protective mechanisms against UV radiation. Melanin is certainly the most important. These pigments are responsible for tanning the skin. This protection is only built up when the skin is exposed to the sun. That is why we get sunburn more easily at the beginning of summer than at the end. Our skin is then already in training.

If we use a sun protection factor every day and even with low UV exposure, we deny the skin this training effect and its own protection is not built up. However, as described at the beginning: A cream with SPF never blocks all the radiation. So there is a small training effect even with a product with light protection.

Vitamin D: sun protection yes or no?

Vitamin D is vital for the body. It is formed in the skin with the help of UVB radiation. Even low sun protection factors block the body's own synthesis of vitamin D. That is why many users of a day cream with SPF worry about their vitamin D level. So it looks like a dilemma. Either sunscreen or vitamin D. Now which is more important?

The fact is: in our part of the world it is very difficult to achieve a sufficient vitamin D level through UV radiation. Of course, this also has to do with our lifestyle. We are mostly clothed and often stay in closed rooms. We therefore recommend having the vitamin D level in the blood determined and supplementing accordingly. Regardless of whether it is daily sun protection or not.

SPF or not: what is our recommendation?

Every skin is different, and each individual's need for protection is different. Even here at Beyer & Sons there are different opinions on the subject. Some people use UV protection on their face all year round, while others only use sunscreen when the sun is strong and when they are outdoors. In the end everyone has to decide for themselves, but we have a clear recommendation depending on the UV index.

The level of stress to which the skin is exposed by UV radiation on different days varies. This is measured with the UV index. Incidentally, the UV index is also displayed in the weather app of most smartphones.

UV index 0-2: With this low UV index, we would not recommend sun protection. With the additional effect of a good day care product, the skin is much better served. In the winter months the UV index averages 1.

UV index 3: A sun protection factor in day care is worthwhile depending on whether you are outside a lot.

UV index 6 and higher: With a high or even very high UV index of 6 or more, the day care with SPF should already have a factor of at least 30 and with a UVA seal also offer appropriate protection against UVA rays.


UV rays damage the skin and make it age faster. A day cream with UV protection can help here, but it also has disadvantages. If you are considering a day cream with SPF, you should keep an eye on it and decide based on your own protection needs and the current UV index.

The table compares our skin cream +, Dayshade Cream SPF 30 and conventional day care with SPF. With the most extensive active ingredients and a skin-like cream base, Skin Cream + has the best care properties for the skin. Dayshade Cream SPF 30 offers good protection against UVA and UVB rays and still has good care properties. Conventional day care with an SPF of 20 (without UVA seal) has insufficient UV protection and only has a small number and amount of anti-aging active ingredients.
