"Why Some People Get Acne and Others Don't"
"The bacteria that cause acne live on everyone's skin, yet one in five people is lucky enough to develop only an occasional pimple over a lifetime."
"Propionibacterium acnes Strain Populations in the Human Skin Microbiome Associated with Acne"
"We compared the skin microbiome at the strain level and genome level of Propionibacterium acnes, a dominant skin commensal, between 49 acne patients and 52 healthy individuals by sampling the pilosebaceous units on their noses."
