The epidermis is the outer layer that is tough and meant to
provide protection. It is made up of thin layers and does contain
the fibrous protein, keratin. Melanin resides in this layer and
although melanocytes provide the pigment of the skin, the
amount of melanin produced is what determines skin color. The
epidermis is completely recycled every four weeks.
Dermis .....ANSWER.....◦Dermis: inner supportive layer
Connective tissue or collagen
Elastic tissue
The dermis is the second, inner layer and consists mostly of
collagen. This layer allows our skin to stretch and move with our
body. The nerves, sensory, receptors, blood vessels, and
lymphatics all live in this layer.
