Quizplus · Accepted Answer

Keratin is a protein that forms the structural framework of the epidermis and also hardens and makes the cells water-resistant. It is found in the stratum corneum, which is the outermost layer of the epidermis. It is not found only in the hypodermis, carried by dermal blood vessels, or a pigment that darkens the skin.
