Conditions

Papulopustular Rosacea

Brief summary

The overall objective of this study is to assess how the use of the drug may shift the skin microbiome and skin biophysical properties. Specifically, the study objectives were to assess the following: * How the drug affects the skin microbiome compared with vehicle when applied once daily for 8 weeks in subjects with papulopustular rosacea. * How the drug affects the skin physical properties compared with vehicle when applied once daily for 8 weeks in subjects with papulopustular rosacea.

Interventions
