Corneocyte
a flattened, non-living skin cell that makes up the outermost layer of the epidermis, the stratum corneum. Formed as keratinocytes migrate upward and lose their nuclei, corneocytes are packed with...

Lamellar Structure
the highly organized, layered arrangement of lipids in the skin's outermost layer, where fatty molecules stack into orderly sheets between skin cells. This ordered configuration is what makes the barrier...

Barrier Lipids
the fatty molecules, mainly ceramides, cholesterol, and free fatty acids, that fill the spaces between cells in the skin's outermost layer. Together they form a water-resistant matrix that holds moisture...

Humectant Magnet Effect
an informal way of describing how humectant ingredients attract and bind water molecules, drawing moisture toward the upper layers of the skin much like a magnet. In dry conditions, humectants...
