What is "stratum granulosum"?

The stratum granulosum is a thin layer of the skin's epidermis composed of cells called granular cells, which play a crucial role in the production of keratin and the formation of the skin's barrier function. These cells contain granules that release lipids and proteins, contributing to the hydration and integrity of the skin.

Examples

1. Starting from the deepest layer and working out, there is the Stratum Basale, the Stratum Spinosum, the Stratum Granulosum, the Stratum Lucidum and the Stratum Corneum.

2. One day later, around 48 hours in to the restoration of your epidermis, a new Granular layer (Stratum Granulosum) can be seen.
