Water Transport in the Stratum Corneum (N/A)

Water transport in the stratum corneum (SC) is a complex process that governs the movement and regulation of water through the outermost layer of the skin. The SC acts as a crucial barrier, controlling both water loss from the body and water uptake from the environment. This function is critical for maintaining skin hydration, integrity, and overall homeostasis. The SC's unique "brick-and-mortar" architecture, composed of corneocytes embedded in a lipid matrix, plays a central role. The organization and composition of these lipids, along with the presence of natural moisturizing factors (NMFs) within corneocytes, determine the efficiency of water transport and barrier function. Disruptions in this system can lead to various dermatological conditions characterized by impaired barrier function and abnormal water loss.

N/A - This is a complex system, not a single target with a specific mechanism of action. Drugs interact by modifying the lipid matrix, enhancing water binding, or reducing inflammation that damages the barrier.
