The cornified layers of the epidermis, also known as the stratum corneum, are the outermost layer of the skin composed of dead, flattened keratinocytes that provide protection against environmental stressors and water loss. These cells are continuously shed and replaced by new cells from the underlying layers of the epidermis to maintain skin integrity and barrier function.
The upper layer of skin is called cornified layer.This is made up of dead cells thus it forms a hard coating over the skin which protect us from bacterial invation or infection and reduces waterloss by evaporation.
The five layers of the epidermis from outermost to innermost are: Stratum corneum Stratum lucidum Stratum granulosum Stratum spinosum Stratum basale (also known as the stratum germinativum)
Cornified keratinocytes
The epidermis is the outer layer of skin, this goes for almost all animals and plants. In mammals the epidermis consists of four to five separate layers, the top layer is made up of cornified cells, which form the primary protective layer. This layer is constantly renewed by releasing dead cells and advancing new cells. The bottom layer creates new cells which then start their journey to the top layer.
Yes, the stratum corneum consists of layers of cornified dead cells. They are strong, full of keratin, and contain no nucleus.

Heat regulation
The outer most layer of the skin is called epidermis.Many of the cells of epidermis produce protein called keratin. The new epidermal cells are formed at the base of the skin and hence the older cells are pushed to surface. The surface cells protect the inner new cells.Gradually the surface cells get filled with keratin. This process is called kertinization.During this process the epidermes gets dividd into five distinct regions.Top most layer is stratum corneum. It consists of more than 20 layers of dead cells. These cells get filled with keratin. These cells are said to be cornified. The cornified cells are surrounded by a hard protective envelope,which makes the skin waterproofing....more over there are other layers of epidermis which has its independent function.
