Dermal Thickness

Meaning

Dermal thickness refers to the measurable depth of the dermis, the layer of skin situated beneath the epidermis, which is primarily composed of the extracellular matrix containing collagen, elastin fibers, and ground substance. This structural parameter is a key clinical indicator of skin health, resilience, and biological aging, directly reflecting the integrity of the connective tissue framework. Optimal dermal thickness is essential for maintaining skin elasticity, hydration, and mechanical strength, and it is significantly influenced by systemic hormonal status and overall physiological vitality.
