The skin barrier is the outermost part of the skin, and is composed of lipids (oils) and cells. This layer is permeable and regulates which organism and substances can enter and/or leave your skin. It acts as both an antimicrobial system but also as a water regulating barrier. Simply put the skin barrier is important because it keeps water in and bad microbes out. So how does it do it?
Did you know that there is a relationship between your skin’s overall health and the state of of its microbiome (aka flora)? Similar to how our gut flora aids in our digestion and affects our overall health, our skin’s microbiome has a significant effect on our skin’s health, including the prevalence (or absence) of acne.
