Skin barrier function restoration via occlusive moisturization

Skin barrier function restoration via occlusive moisturization is a treatment approach that involves applying substances (occlusives) to the skin to form a physical barrier over the stratum corneum, thereby reducing transepidermal water loss and promoting the restoration of normal epidermal hydration and lipid structure[1][3][9]. Occlusive moisturizers like petrolatum, mineral oil, and dimethicone are commonly used and act by trapping water in the skin, restoring and maintaining the integrity of the skin's barrier. This approach is widely used in managing dry skin and inflammatory dermatoses by improving barrier function and reducing symptoms such as itch and irritation[1][3][7][8]. However, this is a therapeutic mechanism, not a discrete molecular target.
