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.
It is a protein called keratin.
keratin through the process of keratinization
Keratin is a tough, waterproofing protein. Keratin is secreted by the cells of the epidermis (the outermost layer of skin).
Epidermis is a skin layer with five sublayers. One of its sublayer is the Stratum Granulosum or the Granular layer which secretes the waterproofing glycolipid that controls water loss in the epidermis.
which is a protein that makes the skin waterproof
Yes it is! And Melanin is responsible for the skin of dark-skinned people.
The three layers of the skin are : # Epidermis, which provides waterproofing and serves as a barrier to infection, # Dermis, which supports and anchors the skin, # Hypodermis (subcutaneous adipose tissue layer).
Mitosis is responsible for repair of your skin following a sunburn.

there is no such membrane. It is just skin which is composed of skin cells. Although, it could be said that skin is partially semi-permeable since it sucks oxygen and excretes sweat and vapor.
No, the stratum corneum is the first line of defense in the skin against pathogens. It consists of a layer of dead keratinized cells that provide waterproofing and protect underlying layers of skin.
