Sunbathe in the pool
The summer is in full swing and the holidays, the long days and the sun literally push us to go out. We go to the outdoor cafe, sit on the terrace, go to the pool or sunbath. To enjoy the good weather, the sunscreen must of course be in the bag!
In recent years, the supply of sun creams, lotions and sprays has increased dramatically, not to mention the distinction between "mineral" and "chemical". What if you stood in front of a shelf full of possibilities?
In general, sunscreens are divided into two parts: protection by physical or chemical filters, physical filters usually consisting of "mineral" substances and chemical filters of "chemical" substances. However, it should be noted that inorganic and chemical filters are composed of chemical compounds, physical filters being inorganic materials and chemical filters being organic filters.
Physical filters are becoming increasingly popular as they are considered natural and healthy; However, they are not new because physical filters are used since the 80s. In most cases, titanium dioxide and zinc oxide are used. These act like particles on the skin as a protective shield and reflect the ultraviolet radiation so that it does not get into the skin. For example, the description of hundreds of small mirrors on the skin is used as an example.
Titanium dioxide and zinc oxide contain white pigments and are therefore also used in many other products. Zinc oxide, for example, in zinc ointments. Titanium dioxide is also widely used and is identified in food products under the number E171 and in cosmetics under the number Cl77891.
Because of their white color, the application of sunscreen can lead to a whitish film on the skin ("whinging"). To avoid this and offer better protection, both substances are often used in the form of nanoparticles. Because the smaller the particles, the more you can find in one place to think in all directions and the cream is transparent. See more under Health & Environment later
Sunscreens based on chemical filter fabrics have existed since the 1920s and 1930s, while sunbathing knew their first true trend and that a tanned skin was no longer seen as a mere sign of the sun. belonging to the working class. Trips to the Mediterranean have become more popular and the summer and swimwear more revealing. Of course, it was also the sunburn you wanted to avoid.
After the application, the chemical filters contained in the sun creams penetrate into the superficial layer of the skin and together form a protective film. UV rays are not reflected, but absorbed and converted by chemical processes into thermal energy. For a sunscreen with chemical filters, wait a little (20 – 30 min.) Until you are exposed to the sun for optimal protection. In addition, the ingredients usually decompose after 3 to 6 months. So you have to buy a new sunscreen each year.
As chemical filters are used among others:
Methyl and methoxy compounds *
(Substances marked with * will be discussed later in the Health and Environment section)
In total, about 30 different filter materials are used.
Incidentally, there are also preparations that use physical and chemical filters to maximize efficiency and unify the benefits of both.
Health and environment
Sunscreens are not only used today to prevent the aesthetic drawbacks of sunburn, but primarily to reduce the risk of skin cancer associated with UV rays.
Nevertheless, sunscreens also have their disadvantages. On the side of the physical filter materials, titanium dioxide is harmless to humans. The same goes for zinc oxide, which is often not tolerated by people with dry skin or skin diseases. With regard to nanoparticles, the results of current research show that they can not enter the body through healthy and unharmed skin. However, possible effects of nanoparticles on the environment are suspected (especially for the sea and its inhabitants), but they must be deepened in subsequent studies. For example, the COSMOS seal prohibits the use of nanoparticles, while others exclude them in part (eg ECOCert), but some, in turn, accept them (eg NaTrue). In general, nanoparticles must be labeled in the EU and can be found as an indication in the ingredients.
In contrast, chemical filters can cause allergic reactions very quickly and irritate the skin because free radicals form when ultraviolet radiation is converted into heat. In addition, substances such as octocrylene, benzophenone, methyl compounds and methoxy (eg, 4-methylbenzylidene camphor) can affect hormonal balance, metabolism and the immune system (allergies). It can not be ruled out that some of these substances increase the risk of cancer. Therefore, if these products can not be completely avoided, one must at least take a look at the ingredients in order to avoid the most dangerous ones.
Oxybenzone and octinoxate are also part of the substances subject to authorization as it has been proven that they contribute to coral bleaching. It is impossible to answer conclusively to the harmfulness of the other substances.
Conclusion and summary
Chemical filters are certainly not recommended for health and the environment, while physical (mineral) filters without nanoparticles are harmless to the human body. For ingredients, you must make sure that no nanoparticles are included (labeled nano in the INCI list). Those who want to be safe use certified sunscreen.
Sun creams should be applied generously every few hours or after bathing. In general, of course, sunbathing, with or without sunscreen, should not be overestimated. If you do not want to do without an intense tan, but you also do not want to tan extensively, we recommend using a self-tanner. Self-tanning natural cosmetics are effective and completely harmless. In Australia, for example, already widespread.
All the sunscreens you can find at Blanda Beauty do not contain nanoparticles. Many are also associated with nourishing ingredients, such as herbal oils, herbal extracts or aloe vera juice, making it a perfect day care all year round.
