Yes, keratin is a protein found in dead skin cells.
Keratin and Skin Cells
- Keratin is a fibrous protein that makes up the outer layer of skin, hair, and nails. It provides structure and protection.
- Keratinocytes are the primary cells in the epidermis (outer layer of skin). As these cells mature, they produce keratin and move towards the surface, eventually dying and shedding as dead skin cells.
The Role of Keratin in Dead Skin Cells
- The stratum corneum, the outermost layer of the epidermis, is composed mainly of dead keratinocytes packed with keratin.
- Keratin gives the stratum corneum its tough, waterproof nature, protecting the body from environmental factors.
- This layer constantly sheds and is replaced with new cells, ensuring the skin's integrity.
In summary, keratin is a protein found in dead skin cells, specifically in the stratum corneum. It plays a crucial role in protecting the body and maintaining the integrity of the skin.
