What is the difference between UVA and UVB?
UVA and UVB stand for UV rays of different wavelengths. UVB have more energy, but penetrate less deeply into the skin than the lower-energy UVA rays. Both UVA and UVB rays ensure tanning, UVA radiation is also responsible for skin aging and an increased risk of skin cancer.
UVB, on the other hand, also stimulates the formation of protective light calluses and can possibly lead to sunburn.
UVA ›› skin aging
UVB ›› sun edge
The specified SPF of a sun protection product relates purely to protection against UVB radiation. However, if the UVA mark is on the label, you can assume that the UVA protection makes up at least one third of the UVB protection. The Déesse face sun cream offers a UVB protection of 30 and a UVA protection of at least 10.
I don't want to start my vacation completely pale - can I prepare my skin for the sun in the solarium?
The answer is a resounding yes and no. The benefits and risks of solariums are controversial, which is why we tend to use appropriate cosmetic products. These conjure up a wonderful, natural tan without any risk. If you start using the Déesse Sun Express for sensitive skin regularly around 4-6 weeks before your holiday, you will increase the synthesis of melanin in the skin, which means that you will achieve a more intense tan faster as soon as you are in the sun.
But be careful : These products do not offer sun protection!
Can the sun protection be increased by repeated application or by applying several different products?
No, in principle SPF values cannot be added. Nevertheless, repeated applications and also the layering of several products with SPF make sense. On the one hand, this is due to the fact that the chemical light protection in the skin degrades over time. So to make sure that the initially selected protection factor really unfolds its full effect, you should reapply cream at least every two hours. On the other hand, for most people, the amount of cream actually applied is well below the recommended amount, which means that the SPF that is advertised on the packaging is below the level.
What else do you have to pay attention to when applying lotion?
Most sun creams have an application time of approx. 30 minutes, which means that the full effect is only achieved half an hour after applying the cream. There are also some parts of the body that are often forgotten. This includes ears, backs of hands and feet, soles of the feet (at least if you lie on your stomach during the day), neck and - especially with sparse hair or a bald head - the head.
Do clouds and shadows protect against UV radiation?
Yes and no.
Although a closed cloud cover can actually filter and thus reduce the UV radiation, if the cloud cover is broken through, this can even increase the UV exposure because the clouds reflect the rays. You should therefore ensure that you have adequate sun protection even when the sky is cloudy. Staying in the shade is definitely recommended (especially between 11 a.m. and 3 p.m.), but it does not provide complete protection either, since the UV radiation is broken on its way to the surface of the earth and thus not only vertically from above, but so to speak " from all sides ”meets us. So while it is less likely, but not impossible, to get sunburned in the shade. You should therefore not do without sun protection even in the shade. The positive thing is that you can get tan even in the shade.
Why do some sun creams stain clothes?
Slipped into the new summer dress freshly creamed and it happened: yellow spots! This is very annoying at the moment, but curiously, it is actually a quality feature, because these stains are caused by contact with oil-soluble UV filters, which give off their color to the respective textiles. However, you can at least limit this problem with a few tips and tricks: As a preventive measure, let every sunscreen soak in thoroughly before you get dressed and choose non-sensitive materials such as cotton, which you can wash at higher temperatures. It is best to treat fresh stains with washing-up liquid (degreasing agent) and then wash the garment as hot as possible. With white laundry, a packet of baking powder, which is sprinkled on the moistened fabric, can help. Leave the baking powder to work for about half an hour and then wash the item of clothing as usual.
