What is the Meaning of Skin Barrier Function?

Skin barrier function refers to the primary protective role of the outermost layer of the epidermis, the stratum corneum, which acts as a physical and immunological shield against the external environment. This function is essential for preventing excessive transepidermal water loss (TEWL), maintaining hydration, and blocking the entry of pathogens, allergens, and irritants. Optimal skin barrier integrity is crucial for dermatological health and is significantly influenced by hormonal status and the aging process.

What is the Origin of Skin Barrier Function?

This term is central to dermatology and skin physiology, combining "Skin Barrier," describing the physical structure, with "Function," referring to its protective role. The structure is often likened to a "brick and mortar" model, where corneocytes are the bricks and the lipid matrix, rich in ceramides, cholesterol, and fatty acids, is the mortar. Hormonal changes, particularly the decline in estrogen, directly impact the synthesis of these key barrier lipids.

What is the Mechanism of Skin Barrier Function?

The physical mechanism is primarily mediated by the continuous lipid lamellae found in the intercellular spaces of the stratum corneum. These highly organized lipids create a hydrophobic seal that limits water evaporation and prevents the penetration of water-soluble substances. Furthermore, the skin's acidic mantle (low pH) acts as a chemical barrier, supporting the resident microbiota and inhibiting pathogen growth. Hormones regulate the keratinocyte differentiation and lipid synthesis pathways, ensuring the continuous renewal and repair of this vital protective layer.
