Study finds that there are acne strains that can promote healthy skin

Dealing with acne problems? Did you know that there are certain acne-causing bacteria that are also widely spread on individuals with healthy skin?

After looking into the biological effects of various strains of Cutibacterium acnes singled out from human skin, scientists found that the nonpathogenic strain of C. acnes can boost the skin’s resistance against Staphylococcus aureus—a bacteria that can cause infection.

According to the new research’s lead author Ayano Tsuru, it “is likely that C. acnes maintains skin health by inhibiting common pathogens like S. aureus from invading skin tissue.” 

The findings in the new study published in the Microbiology Spectrum of the American Society for Microbiology stated that “ribotype (RT) 4 and 8 strains, a classification of bacteria strains based on polymorphisms in rRNA, which are often detected in the skin of individuals suffering from acne, shortened the lifespan of the nematode, while RT6 strains that are often found in the skin of people without acne, did not,” according to a report by ANI. 

The collaborative research by Osaka City University and Okayama University discovered the other side of acne bacteria that can yield some benefits on the skin through the ribotypes associated with the absence of acne.

“This reminds us that when evaluating the biological effects of certain bacteria, there is a need for a discussion at the strain level,” said Eriko Kage-Nakadai—a professor at the OCU Graduate School of Human Life Science who also worked as a study advisor.
