What is the function of keratin in the epidermis?

Text Solution

Verified by Experts

The epidermis is the outer layer of the skin made of epithelial tissue. The epidermis contains keratin-secreting cells (keratinocytes). Keratin is an insoluble protein contained in the surface of the skin, which provides protection and impermeability. In mammals, keratin also forms hair. The keratinized cells of the surface of the skin form the corneal layer. These cells die and are continuously replaced by others.
