Skin Barrier Function Enhancement

Molecular classification
Lipid synthesis, Protein expression, Barrier Function
01

Overview

Skin barrier function enhancement refers to strategies, molecules, and interventions aimed at improving the integrity and performance of the skin’s outermost layer—the stratum corneum—thereby reducing water loss, increasing hydration, and protecting against irritants and pathogens. This target is not a single molecule or receptor but rather a physiological process involving multiple molecular pathways and structural components, including stratum corneum lipids, corneocytes, natural moisturizing factor (NMF), and lamellar bodies.

02

Mechanism of action

Restores skin barrier integrity by enhancing lipid structure and reducing transepidermal water loss (TEWL). Modulates inflammatory responses and promote healthy skin lipids.
