Effects of Oral Supplement Containing L-Histidine and Antioxidants on the Skin Barrier Function and Systemic Inflammation in Rosacea

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate how supplementation will alter the skin and the gut barrier and inflammation in those with rosacea.

Detailed Description
-----------------
Rosacea is a chronic inflammatory condition that widely prevalent in the general population and is associated with both inflammation and dysfunction of the skin barrier. Gut dysfunction has been shown to be present in those with rosacea. This study evaluates how the use of a supplement may improve the gut and skin barrier as well as reduce general inflammation.
