stratum granulosum
The stratum granulosum, also known as the granular layer, is a thin layer of skin in the epidermis (the outermost layer of the skin) that lies between the stratum corneum and stratum spinosum. This layer contains granule and keratohyalin cells that help in the process of keratinization, where cells change from squamous (flat) to keratin cells, making the skin tough and water-resistant.

Stratum granulosum
The stratum granulosum is a thin layer of cells in the epidermis. Keratinocytes migrating from the underlying stratum spinosum become known as granular cells in this layer. These cells contain keratohyalin granules, which are filled with proteins that promote hydration and crosslinking of keratin. At the transition between this layer and the stratum corneum, cells secrete lamellar bodies into the extracellular space. This results in the formation of the hydrophobic lipid envelope responsible for the skin's barrier properties. Concomitantly, cells lose their nuclei and organelles causing the granular cells to become non-viable corneocytes in the stratum corneum.
