Going on vacation? Do not forget that sunlight — is not only a source of warmness and life but also of the dangerous and carcinogenic ultraviolet. In this article, we will tell you about how the filter of sunscreen creams works, and why you should use them.

Ultraviolet radiation, which is a part of the sunlight we receive, not only makes our skin tanned but also harms it a lot. And sometimes brings irreparable damage by destroying the DNA and causing premature aging, skin dehydration, and cancer.

What happens when the sun shines onto the skin?

The sunlight is a flux of quanta of electromagnetic radiation and the photons. The photons differ: low-energy photons are harmless to biological tissues while the high-energy ones may destroy DNA, and are detrimental to every living thing.

The sun emits electromagnetic waves in a wide range, so different types of photons and radiation travel to the Earth. Fortunately, our planet has got the ozone layer reflecting the high-energy waves. However, even those waves that get to the Earth may be harmful — especially in a high amount.

Speaking of radiation coming through the ozone layer, the most harmful for us are the ultraviolet: soft (UVA, with the wavelength of 320 to 400 nm) and intermediate (UVB, 280-315 nm).

Our tissues contain molecules created for dealing with such photons —and under the influence of them, the molecules start chemical reactions that do not occur without UV radiation. As a result of such reactions in the cells melanin, the pigment that makes skin tanned, is produced.

Also, the UVA gets deep into the skin and destroys the collagen protein — the one responsible for skin firmness, and the UVB burns out and causes redness and soreness. But the main threat is that both UVA and UVB may cause DNA mutations — often turning into a benign tumor.

How to protect yourself?

Of course, you may try to avoid the sunlight (especially in summer), hiding under the parasols and kerchiefs but it is not convenient for everyone. In case you have to go out in the heat, you may use sunscreen cream. Due to the molecules in their compound, all of the creams are capable of reflecting the ultraviolet waves. Even a thin layer of such molecules can take over the UV action (if the molecules act as chemical filters) or simply reflect the harmful radiation (acting similar to the mirrors if the filters are physical).

The most popular among such filters are zinc oxide (the chemical filter) and avobenzone, the physical filter: in order to reflect both UVA and UVB, you need to use their combination. It is important to remember that you need to use a big amount of sunscreen cream to protect your skin.

If you are wondering what quality sunscreen creams are there on the market, we may suggest paying attention to the products of the American brand DERMASKILL. The cosmetics created to minimize the harmful action of the sun include:
