The skin has various functions, primarily defence from infections and trauma. With aging, profound changes occur that compromise its key functions, leading to impaired barrier protection and immune responses. This is in part due to the increased low-grade systemic inflammation known as inflammaging, driven by senescent cells, and release of pro-inflammatory cytokines, to which the skin also significantly contributes. As a consequence of inflammaging, the skin’s function is compromized. The cellular and molecular components involved are summarized in this review. ER -
