Expert Answer:

In case of skin, the stratified squamous epithelium is keratinised whereas the lining of the oesophagus is an example of a non-keratinised or "moist" stratified epithelium.

(In case of keratinised stratified epithelium, the most exterior layers of cells are dead and lose their nucleus and cytoplasm, instead they contain a tough, resistant protein called keratin. This specialisation makes the epithelium waterproof, so is found in the mammalian skin.)
