Details of studies included in scoping review: Probiotics, prebiotics and synbiotics as oral supplements for skin health, function and disease throughout the life course
This scoping review aimed to map the body of literature on the role of oral probiotics, prebiotics and synbiotics in maintaining and optimising skin health and function as well as preventing and managing skin conditions through the life course. Six electronic databases were systematically searched and results considered for inclusion by two reviewers using previously established criteria. Finally, 516 studies were included in the scoping review, including 73 systematic reviews.

A pilot data extraction of 10 studies was performed by two reviewers independently and any differences discussed to ensure consistency of approach. Subsequent data was extracted by one reviewer. As the number of included studies considerably exceeded that originally anticipated, the decision was taken to opt for verification of a proportion of the extraction (around 15%) by a second reviewer to balance accuracy and feasibility. Any disagreements that arose between the reviewers was resolved through discussion, or with an additional reviewer.
