Latest studies demonstrated that deodorants can alter our body’s bacteria.
Over the last years, cosmetics such as deodorants or antiperspirants have helped people to prevent body odor. However, little is known about the fact that a simple splashing can modify our skin’s ecosystem.
According to a new research, there are thousands of bacteria types living on human skin. Most of them can be found in the armpit. Therefore, using deodorants or antiperspirants can have a huge effect on the type and quantity of bacteria.
This research was conducted in order to see how these products may affect the microbial life on our bodies. The main author of the study said that:
“we want to know if any changes in our microbial ecosystem are good or bad, but first we have to know what the landscape looks like and how our daily habits change it”.
There were 17 individuals involved in the study. Each of them used deodorant, antiperspirant or neither for eight days. Firstly, scientists took samples of DNA from the armpit so as to find more about microbial structures here.
Next, individuals were told not to use any products; researchers’ aim was to find which type of microbes would reappear. On the last day, all the participants used an antiperspirant before scientists took the last sample.
During the research it was discovered that various types of bacteria grew on people regardless of the products they used. Many of these bacterial forms were unidentified. Overall, those who didn’t use any products presented populations of Corynebacteria bacteria.
They had also smaller populations of Staphylococcaceae bacteria, but 10% of their samples couldn’t be identified. Those who used deodorant had a larger quantity of bacteria in the first day. In one week they had more Staphylococcaceae that the others and some of them presented Corynebacteria.
However, the amount of unidentifiable bacteria on their body was only 5%. In the last day, when all the individuals used antiperspirant, the majority of the microbial forms died off. After this study, researchers claim that it is still difficult to say what microbial activity is harmful or helpful.
What’s more, they added that the unidentifiable bacteria shouldn’t be something to worry about. Even if particular types of Staphylococcaceae are known to be harmful, most of them aren’t. Their only strong conclusion was the fact that bacteria tends to grow faster if we stop using cosmetic products.
Maybe deodorants can alter our body bacteria, but we will still use them to smell better and maybe ease our way into social life.
