Endocrine disruptors, why be wary?

According to a study, women's urine is twice as concentrated in endocrine disruptors as men's. This difference is due to the fact that they use more cosmetics than men. In summary, regular users of cosmetics (regardless of gender) would be much more exposed to disrupters and therefore much more likely to develop serious diseases. Yes, it's scary!

At SAVAN we want to take care of our skin and we would like it to be safe! So we've gathered a lot of important information about endocrine disruptors in cosmetics and you're also given some tips on how to avoid them in your cosmetics.

Endocrine disruptors, what is it?

Endocrine disruptors are substances, synthetic or natural, that disrupt our hormonal system. Our hormones are in fragile balance and a disruption of their proper functioning can lead to serious problems. The most important risks are the decline in fertility as well as hormone-dependent cancers (some cancers of the breast, ovaries, prostate) and the poor development of fetuses in the case of pregnant women.

In general, endocrine disruptors are used as pesticides or preservatives and are therefore present in many elements of our daily lives. They can be found especially in water, in some fruits and vegetables (because of the use of pesticides) or in meat (disrupters can accumulate in animal fat). In cosmetics, they are most often used as preservatives, antiperspirants, synthetic perfume or chemical UV filter.

What are the effects on the body?

The mechanism of the disturbers is not certain and depends on each substance! One of the most suspected mechanisms is the binding of disruptors on hormone receptors, thus preventing their proper functioning. This process disrupts the synthesis or transformation of hormones.

The consequences are multiple and never great: change in the appearance or weight of certain glands producing hormones, impacts on the sexual elements of the fetus, development of tumors or cancer cells ... Disrupters are particularly dangerous for pregnant or lactating women , since they can have a great impact on the development of the fetus and since they also pass into breast milk. Not very reassuring all that ..

Endocrine disruptors in your cosmetics, a real problem!

In cosmetics, disrupters are present in all kinds of products! So always be on guard: shower gel deodorant through your moisturizer.

Among the most common are the parabens. They have long been used in large quantities as preservatives because of their high efficiency and low cost. They are still present in a lot of creams, shower gels or shampoo. The list of its suspected adverse impacts is long: male infertility, damage to DNA, cancer cell proliferation help ...

Other disrupters, which are probably the hardest to avoid are the aluminum salts. They are used in almost ALL deodorants. They are even more dangerous because they are applied on the armpits, parts of the sensitive body and very close to the chest. Some studies suggest a link between the use of deodorant and the fact that the most common breast cancers develop in the upper breast, that is to say the closest to the armpits. Although none of these studies has clearly established a direct link between aluminum use and cancer, all of this remains highly studied and monitored by researchers.

Warning ! We sometimes hear about alum stone as a natural alternative to deodorant, but it also contains aluminum salts, so we also avoid! (An opportunity here to remind that "natural" does not mean without risk ...).

But it does not stop there! Sunscreens are also subject to much controversy. There are UV filters that block or absorb UV rays. These substances are not present only in sunscreens, but also in some lipsticks or moisturizers with sunscreen. These controversial substances are also suspected to have interactions with hormone receptors and thus to have effects such as stunted breast growth in girls or changes in the child's weight. when the mother has been exposed. In addition to all this, many harmful effects have been discovered for animals and waiting to be tested on humans. (Before leaving in fear and eliminating the sunscreens of your life, wait for our next article ... it remains that the sun can also cause great damage).

plastic potIn addition to deodorants and sunscreens, all products containing fragrance potentially contain disrupters. Indeed, the term "perfume" or "fragrance" in a list of ingredients does not specify all the substances it contains. We are in a total blur concerning these products. There are often the phthalates, another endocrine disruptor that is also in the plastic packaging and can migrate to the product. These packages also sometimes contain Bisphenol A, who, you will understand, is also a disrupter that you do not want to find in your products, believe us!

One of the things that worries researchers the most is the phenomena of synergy between different disrupters. These phenomena are very difficult to study. Despite the minimum doses regulated, we do not know the effect of cumulative disrupters, even in small quantities. So, even if the disrupters in your shampoo had no impact on your health, associated with your deodorant which also contains, it is difficult to calculate the real risk!

In conclusion, endocrine disruptors are present in a large part of cosmetics. To avoid them and aim for a safe routine, find our advice in the following article: "Endocrine disruptors in our cosmetics, how to avoid them? "
