简要总结
This single center, randomized, 15-day clinical trial is being conducted to assess the changes to the skin microbiome of induced wounds on the back in approximately 35 healthy adult subjects aged 18-55 years, with Fitzpatrick Skin Types I - III. Microbiome and skin physiology assessments will be completed.
