Dermal Integrity

Meaning

Dermal integrity refers to the robust structural and functional health of the dermis, the layer of skin situated beneath the epidermis. This is characterized by the quality, density, and organization of its extracellular matrix components, primarily collagen, elastin, and glycosaminoglycans like hyaluronic acid. Maintaining this integrity is paramount for the skin’s barrier function, mechanical strength, elasticity, and overall aesthetic appearance, serving as a key indicator of biological aging and systemic health. Hormonal factors, notably estrogens and androgens, significantly influence the dermal fibroblast activity and matrix turnover.
