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: it brings something 

Why is sun protection so important 

You know the typical effects of sun rays on the skin. They make the skin look complexion, but can instantly cause dry skin, redness and sunburn. In the long term, even wrinkles and skin cancer.

Ultraviolet radiation is to blame for UV radiation. Based on the wavelength, science differentiates between the types of radiation UVA, UVB and UVC. The UVC rays from the sun do not make it 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.
  • You causedRedness and sunburn.
  • Skin cancer is also a consequence 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 tones the skin darker and is able to convert the radiation into harmless heat. But even this self-protection has its limits: Depending on the skin type, the body's own sun protection lasts only a few minutes for light skin types to about an hour for dark skin types.n). 

In order not to endanger your skin in the first place, you should apply sun protection in the form of sun cream or sun oil.

How does sun protection work with sun cream and oil 

You can also protect your skin against UV radiation with sun oils or sun creams. They bring with them two mechanisms of action, 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 away from the skin. 

This protection is very effective. However, it 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 and thereby render it harmless to the skin. The only problem is that chemical sunscreen isn't always good for your skin or the environment. Organic filters such as Oxybenzone, Octocrylene, and Octinoxate, for example, pollute coral reefs and are partly also hormonally effective. Unfortunately, it is precisely these substances that are used particularly frequently in sun creams.

Therefore our tip: Before you buy a sunscreen or sun oil, check the ingredients! You can do this, for exampleCode 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 supply 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 are supposed to protect your skin from UV radiation and have UV filters in their formulation. Depending on the level of the sun protection factor, the proportion of UV-filtering substances can 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 to 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? 

Unfortunately, in our opinion, the answer is yes and no.

Sunscreen and anti-aging creams have different functions and, accordingly, different formulations. It starts with the cream base, which varies 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 take care of your skin, but it will not develop the same anti-aging potential as a specialized face cream.

So it all depends on what you want one good sunscreen or one 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 do not expose your skin to the direct sun, you protect it best. 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, this comes with some restrictions: You should not be looking for any walks or sports in the sun or a summer tan. 

So if you want to spend some time in the sun without sacrificing your antiaging care products or risking sunburn, here's what you can do:

Apply your nourishing day cream as usual and let it absorb well. Then apply your sunscreen with mineral filters for sun protection. This allows the nourishing ingredients of your face cream to penetrate the skin and unfold their effect, while the physical UV filters protect your skin against radiation.

With chemical UV filters, the order would be reversed: the chemical blockers have to penetrate the skin in order to take effect. A day cream would only get in the way. However, since the chemical filters are not always perfect for reasons of skin health and environmental compatibility, sunscreen with mineral filters seems to us to be the better choice.

Enjoy the sun and take good care of yourself! #staysober

My dermatologist advised me to do more for my mature skin. I came across Sober on the Internet. I have been using the Hydra Defense face cream for 2 months. With success! I'm very satisfied. Thank you!

High quality goods

Timeshift Anti-Aging Serum - A great product for daily skin care. The serum has a pleasant smell, perhaps due to the green tea extract it contains. I applied it every day and it feels very comfortable on the skin. Great product and gladly again ..

EXPERIENCE THE SOBER QUALITY

Best facewash I have ever used

Risking to sound too overexcited, this is really the best I've tried! My skin feels very soft already after the first use, and the effect never disappoints. Redness has considerably improved; pores, too. Additionally to daily cleaning, once a week i leave it on my skin for some minutes, and i can feel a good but gentle peeling effect. Simply everything is nice about it, including packaging, look, smell etc. One small space for improvement:the dispenser sometimes chokes or gives out very little, but it recovers after another push.

Accompanies my everyday life

Top products at a fair price, if you include quantity and individuality. Nice that natural ingredients are used. Delivery was quick, advice was great and very friendly. Definitely recommendable.
