According to a report by the US Daily Science website on December 2, the latest research results published by Aston University in the United States in the bimonthly "Applied Microbiology" show that most of the cosmetics in use, such as beauty eggs, mascara and lip gloss , Are contaminated by super bacteria that may be life-threatening.

New research led by Dr Amlin Bashir and Professor Peter Lambert of the Aston University School of Life and Health Sciences shows that millions of people in the UK use cosmetics that are potentially contaminated with potentially lethal bacteria every day, such as E. coli and staphylococci, because most makeup tools have not been cleaned and are used far beyond their expiration date. It is reported that more than 90% of beauty products are found to carry bacteria, and if used near the eyes, mouth or cuts and abrasions, it can cause various diseases from skin infection to blood poisoning.

This risk is increased in people with weakened immune systems, as they are more likely to be infected by germs. Researchers have found that the relatively late concentrations of potentially harmful bacteria in sponges used to make foundations appear relatively late, because the vast majority of beauty eggs (93%) have never been washed, although more than one-third Two (64%) beauty eggs have fallen to the ground during use. For the first time, the research focused on beauty eggs, a very popular makeup sponge used to apply foundation and cream on the face.

The highly regarded celebrity sponge is estimated to have sold more than 6.5 million pieces worldwide. Researchers at Aston University have found that this product is particularly susceptible to contamination because they are usually moist after use, creating an ideal breeding environment for harmful bacteria. Researchers say the results of Yuyao City yazi packaging study show that consumers are unknowingly putting themselves at risk, and manufacturers and regulators should take more steps to protect consumers, more prominently showing the shelf life and Cleaning requirements. EU guidelines require cosmetic brands to adhere to strict hygiene standards and specifically state that E. coli should not be found at any concentration in new cosmetics. However, there is currently limited consumer protection against the risk of contamination of the product in use.
