The 3 layers of skin are: 1- Epidermis...the outer layer of the skin consisting of living and dead cells; contains melanin which gives color to skin and hair; also contains lipids which make skin waterproof.
2-Dermis...the layer of living cells just below the epidermis that houses nerves, blood vessels, hair follicles, sebaceous glands and sweat glands
3-Fatty tissue... layer beneath the dermis that serves to insulate the body’s temperature (Subcutaneous Layer).
