"As viable microbial dietary supplements, probiotics provide health benefits through fighting pathogens and maintaining the homeostasis of the gut and skin microbiome," said study researchers from Rasoul Akram Hospital in Iran.
The present article reviewed the potential of probiotics as beneficial microorganisms for treating acne vulgaris," researchers added.
According to the study, published in Dermatologic Therapy, the increasing resistance to antibiotics has decreased their effectiveness in treating acne.
For the findings, the research team examined the results of all relevant published studies on the use of probiotics in creams or oral medications for treating acne.
The results suggest that probiotics may help augment the skin's natural defences against acne.
"Oral administration of probiotics was found to constitute an adjuvant therapy to conventional modalities for treating mild-to-moderate acne vulgaris," the study researchers wrote.
"Further research is recommended that looks into the long-term effects of probiotics on acne lesions given the short-term type of studies cited," said senior author Masoumeh Mohamadi.
