New research suggests that the US cosmetics industry’s signature cleansers, facial cleansings and scrubs are more effective at cleaning germs than previously thought.

The findings, published in the journal PLOS ONE, come from an extensive study of more than 20 million facial cleansing products that were sold across the country in 2011-2014.

In this study, scientists from the University of Pennsylvania’s Perelman School of Medicine analyzed the results of the products’ microbiological analysis and found that the products that had been sprayed with disinfectant and/or disinfectant-resistant ingredients had significantly fewer bacteria than the products without those chemicals.

“The more disinfectant you spray on the product, the less bacteria are coming out,” said lead author Dr. Elizabeth F. Dominguez, a professor of medicine and microbiology at the Perelmen School.

She added that these products were also less effective at preventing infections when used in conjunction with a moisturizer, since the products did not contain the active ingredients needed to penetrate skin, penetrate the lining of the mouth, and penetrate deep into the skin.

Dominguez said that the results, though significant, were not conclusive enough to recommend that people wash their face before using these products.

Instead, she said, the research team is working on using the results to develop new, more effective products that could be used on a regular basis.

“We don’t think that the facial cleansing products alone are going to eradicate all of the infections that we’re talking about,” she said.

“We think that we need to incorporate other components in our cleansing regimen, and we think that these other components are going in a different way.”

The study also found that a number of other components were also found to have a significant impact on the effectiveness of the facial cleanses.

For example, the researchers found that some of the active components in the facial cleaners had significantly less antimicrobial activity than the ingredients that were sprayed with a disinfectant.

For example, they found that an ingredient called methyl trichloroethanol was more effective than a preservative called methylisothiazolinone in preventing the growth of E. coli.

These antimicrobial components were all found to be present in the products, and researchers are also examining whether they may have a role in the development of more effective facial cleansions.

The study has several limitations, said Domingue, who also serves as a research associate at the Institute of Medicine and a member of the Institute’s Emerging Technologies Advisory Board.

The researchers didn’t have the data needed to identify the specific ingredients used to make these products and how they were different from those in other products.

Additionally, it’s unclear if other components of the product were also responsible for their effectiveness.

For example the researchers didn’ t have data to show that certain ingredients in certain products were more effective, or if some of these ingredients could also have a beneficial effect.

The researchers said that future research could examine the impact of other ingredients, such as fragrance, in making facial cleansives.

However, they noted that this is the first study to find that ingredients in the same product can have different effects on different bacterial species.

“This is an exciting development because we now have a better understanding of the mechanism of action and the mechanisms of action that are going on behind the efficacy of these products,” Domingo said.
