The purpose of this study is to determine how probiotics affect sebum production and gut health in those with acne vulgaris.
Probiotics have been shown in previous pilot studies to be helpful in acne and this study aims to examine how the gut microbiome and skin biophysical properties are shifted in those with acne vulgaris. In particular, this study will assess the influence of oral spore based probiotics on the skin sebum production and will assess how probiotics influence the gut microbiome and the blood levels of short chain fatty acids.
