If you have ever used makeup, thenWe sincerely hope that everything is fine with you and the cosmetics are not expired. The fact is that the results of a new study, which is published in the journal Journal of Applied Microbiology, indicate that up to 90% of makeup products are literally teeming with bacteria. At the same time, if you have recently or very long ago, or never even washed makeup sponges and sponges, then the probability that you smear dangerous bacteria such as Staphylococcus aureus, Escherichia coli and Citrobacter freundii every day is very high.
Does the beauty require such sacrifices?
The results of the study showed that up to 90%cosmetics and makeup products can contain a huge amount of deadly bacteria. Researchers at Aston University in the UK tested four types of popular cosmetics found in test subjects' makeup: lipstick, lip gloss, eyeliner and mascara and found alarmingly high levels of bacterial contamination. Moreover, the higher the water content in the mentioned products, the higher the likelihood of contamination.

However, this is not all: scientists are very concerned about the use of sponges and sponges for applying makeup, which have become especially popular in the last few years. As a rule, they are used for applying foundation and they contain a record number of dangerous bacteria and fungi. In total, the team analyzed 467 products - 96 lipsticks, 92 eyeliners, 93 mascaras, 107 lip glosses and 79 makeup sponges. Researchers write in their article that despite the fact that cosmetics should not contain pathogens, from 70 to 90% of cosmetics used are contaminated with bacteria. But where did they come from?
Researchers polled for reasonsowners of contaminated cosmetic products and found that the problem was most likely due to errors during makeup. However, the shelf life of cosmetics is also important. The fact is that after the expiration date the number of preservatives that prevent the growth of bacteria is reduced. So, the results of the 2013 study showed that most of the respondents continue to use cosmetics after the expiration date. But this is not the worst: 93% of respondents admitted that they had never washed sponges and brushes for applying makeup, and 64.4% reported that they used sponges after they fell to the floor. In this case, even if you wash the sponges, the likelihood that they will remain contaminated with dangerous bacteria is quite high. Researchers also report that if the sponges are not dried after washing in warm water with soap, the germs will continue to multiply even faster.
