Lichtschutzfaktor in Sonnencreme bedenklich

Sun protection factor (LFS) in skin creams:how good are sun creams with sun protection?

The sun is back and it is time to think about the right protection against UV radiation. Conveniently, some day creams already provide a sun protection factor. But: bring something 

Why is sun protection so important? 

You know the typical effects of sun rays on your skin. They create a complexion on the skin, but can immediately cause dry skin, redness and sunburn. In the long term, even wrinkles and skin cancer.

Ultraviolet radiation is the culprit. Because of the wavelength, science differentiates between the UVA, UVB and UVC radiation types. The UVC rays do not make it from the sun to the surface of the earth, which is why our skin only has to deal with the UVA and UVB rays.. 

The UV radiation has a strong effect. Its rays can penetrate deep into the dermis and cause some damage: 

  • UV radiationdries out the skin.
  • It causedRedness and sunburn.
  • Skin cancer is also a result of UV radiation.
  • Through them arisefree radicalsthat weaken the connective tissue of the skin.
  • Thereby the rays contributeSkin aging and wrinkling at.

Our skin protects itself to a certain extent by producing melanin. Melanin colors the skin darker and is able to convert the radiation into harmless heat. But this self-protection also has its limits: depending on the skin type, the body's own sun protection lasts only a few minutes for light-colored skin types to about an hour for dark-colored skin types.n). 

In order not to endanger your skin at all, you should apply sun protection in the form of sunscreen or sun oil.

How does sun protection work with sunscreen and oil 

With sun oils or sun creams you can additionally protect your skin against UV radiation. They have two mechanisms of action for this, namely mineral sun protection filters and chemical sun protection filters.

Titanium dioxide or zinc oxide are often used as mineral sun protection filters. The minerals protect the skin physically by reflecting the UV rays, so send them away from the skin. 

This protection is very effective. However, he often leaves a white film on the skin and not everyone likes it. For this reason, sunscreens combine the mineral filters with chemical filters.

Chemical filters are able to convert UV radiation into heat, rendering it harmless to the skin. The only problem is that chemical sunscreen isn't always good for the skin or the environment. Organic filters such as Oxybenzone, Octocrylene and Octinoxate, for example, pollute coral reefs and are sometimes hormonally active. Unfortunately, these substances are used particularly often in sun creams.

Therefore our tip: Before you buy a sunscreen or sun oil, check the ingredients! For example, you canCode check use.

Is the sun protection factor of my day cream enough as sun protection 

The function of a day cream is to moisturize your skin and provide it with important nutrients. It should protect your skin from the formation of wrinkles and make its contribution to anti-aging.

Sun creams and sun oils have a different task: They should protect your skin from UV radiation and therefore have UV filters in their formulation. Depending on the level of the sun protection factor, the proportion of UV-filtering substances can already make up a fifth of the recipe!

There are day creams or face creams that provide a sun protection factor. That sounds practical, after all the cream is supposed to protect against the dangers of UV radiation as well as against everyday skin aging factors.

The only problem is: the better an anti-aging cream is supposed to protect against UV rays, the less capacity it has for anti-aging factors. If 20 percent of the formula goes for UV protection, 20 percent is missing for the supply of moisturizing substances, valuable oils and important nutrients for the skin.

Can I use the sun protection factor of my skin cream as sun protection 

In our opinion, the answer is unfortunately: yes and no.

Sunscreen and anti-aging creams have different functions and, accordingly, different recipes. It starts with the cream base, which differs depending on the case, and ends with the composition of the ingredients.

A day cream with SPF will protect your skin from UV rays and care for your skin to a limited extent, but will not develop the same anti-aging potential as a specialized face cream.

So it depends on what you want a good sunscreen or an excellent anti-aging formulation? 

How do I protect my skin from wrinkles and also from the sun 

What you shouldn't forget: The best protection against UV rays is still shade.

If you don't expose your skin to the direct sun, it's best to protect it. So you can also use the nourishing day cream of your choice, wear a protective hat and sit in the cool shade under the parasol.

However, there are some restrictions: You shouldn't be out for walks and no sports in the sun and no summer tan. 

So if you want to spend some time in the sun without sacrificing your anti-aging care or risking sunburn, you can do the following:

Apply your nourishing day cream as usual and let it soak in. Then apply your sunscreen with mineral filters for sun protection. This way, the nourishing ingredients of your face cream can penetrate the skin and develop their effect, while the physical UV filters protect your skin against the radiation.

Incidentally, the sequence would be reversed with chemical UV filters: the chemical blockers have to be absorbed into the skin to work. A day cream would only be in the way. However, since the chemical filters are not always perfect for reasons of skin health and environmental compatibility, the sunscreen with mineral filters seems to be the better choice.

Enjoy the sun and take care of yourself! #staysober
