MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: Preadolescence is an interesting stage during which changes in microbial diversity can coincide with the development of acne. This study is the largest assessment of preadolescent acne microbiome in the literature to date.

In this study, we found that early acne in preadolescent females is characterized by an abundance of Streptococcus mitis, while later stages are characterized by a predominance of Cutibacterium acnes (formerly known as Propionibacterium acnes).  

MedicalResearch.com: What should readers take away from your report?

Response: This study is important as it reveals that microbes other than C. acnes can play a role in preadolescent acne. Although we noted around a 40% clinical reduction in the number of acne lesions, we did not notice a significant change in the preadolescent microbiome after treatment with benzoyl peroxide.

MedicalResearch.com: What recommendations do you have for future research as a result of this work? 

Response: Future research should assess the antibacterial role of benzoyl peroxide in preadolescent acne.
