WATCH VIDEO ABSTRACT: Dermatoporosis: Strategies for Rebuilding the Extracellular Matrix of the Skin.

ABSTRACT

Dermatoporosis as a disease entity is relatively newly described, the title conceived as recently as 2007. The background of chronic skin fragility, bruising, and atrophy appears to start in some patients as early as their mid-forties, but is full blown over the age of 65 years. The dehydration and fragility of the skin with recurrent bruising and breakdown were initially attributed to increased vessel fragility and permeability thought to be associated with inherent vascular tissue defects in a milieu of increased inflammation and extracellular matrix (ECM) degradation. It has subsequently been demonstrated that this ECM breakdown directly affects the structural support system of the superficial vessels, leading to stretch, increased permeability, and vulnerability to mechanical damage. Add to that the ECM atrophy and general accumulation of non-functional metabolic waste products in the form of fragmented collagen, elastin, and increased circulating glycation end products, and it becomes apparent that much of the problem resides in a structural defect, non-functioning, dehydrated, senescent cellular matrix and unsupported vascular system that presents as dermatoporotic characteristics. This paper describes a strategy of ECM replacement to counteract these foundational deficiencies. J Drugs Dermatol. 2023;22(9) doi10.36849/JDD.7549.
