Dermal-epidermal junction

The dermal-epidermal junction is the boundary where the outermost layer of skin (epidermis) meets the underlying layer (dermis). It acts like a strong, yet flexible connection that keeps these layers attached, allowing nutrients and signals to pass through. This junction also provides structural support and helps the skin heal when injured. It contains tiny finger-like projections called rete ridges that increase surface area for better connection. Overall, this junction is essential for skin stability, elasticity, and proper function.
