| Sumario: | Dry skin is one of the indicators of a compromised skin barrier. An intact skin barrier is not only important to reserve the hydration within the epidermal tissue but also to protect our skin from environmental stressors and inhibit pathogen invasion; damage to the skin barrier may lead to inflammatory skin diseases. Some microbial metabolites such as short chain fatty acids may inhibit or destroy harmful bacteria and regulate the host immune system. The impact of the skin microbiome and short chain fatty acids on skin barrier function was studied in two groups of 75 participants each. The cohort was equally divided in dry and moist skin types, based on stratum corneum (SC) functionality index (SCFI), reflecting the ratio of transepidermal water loss (TEWL). A dry group represents a low SCFI and a moist group a high SCFI. Compared with the dry skin group, propionate and <i>Cutibacterium</i> levels (previously known as <i>Propionibacterium acnes</i>) were significantly higher (<i>p</i> < 0.001) in the moist group. Levels of <i>Cutibacterium</i> were negatively correlated with those of <i>Staphylococcus</i> (<i>p</i> < 0.0001) in both dry and moist groups. The moist group also had a significantly higher propionate concentration (<i>p</i> < 0.001). This study showed that the microbial community and short chain fatty acid concentration may be considered as significant determinants of the SCFI of the skin. |
