Stratum Corneum & Lucidum: Understanding the Role of Dead Skin Cells

The stratum corneum and stratum lucidum both contain dead cells.

- Stratum corneum: This is the outermost layer of the epidermis and is composed entirely of dead cells. These cells are filled with keratin, a protein that helps to protect the skin from damage.

- Stratum lucidum: This layer is located just below the stratum corneum and is also composed of dead cells. However, these cells are more tightly packed than those in the stratum corneum and contain a higher concentration of keratin.
