Design outcomes

Primary

MeasureTime frame
To visualize and characterize the presence of skin microbiota as biofilm on healthy and acneic skin using biopsy samples of the back. - To identify acne/phylotype-specific transformations in the immune microenvironments using biopsy samples of the back from healthy and acneic volunteers. - To detect microbial species and phylotypes within the back biopsy from healthy and acneic volunteers. - To isolate and collect the skin microbes for construction of in vitro skin biofilm models. Timepoint: baseline visit

Secondary

MeasureTime frame
To evaluate other skin clinical parameters: sebum content, skin erythema, itching, dandruff and UV fluorescence. - To evaluate skin/scalp disorders (itching/dandruff), possible aggravation factors & cosmetic routines and see if itching and dandruff can be correlated.Timepoint: Day-3 & Day 0
