The Stratum Corneum
the outermost sublayer of the epidermis, made of flattened, dead keratinocytes embedded in a lipid matrix that together form the skin's main barrier. It limits water loss and blocks entry...

The Hypodermis (Subcutaneous Layer)
the deepest layer of the skin, located beneath the dermis and composed mainly of fat and connective tissue. It cushions underlying muscles and bones, insulates the body against heat loss,...
