You probably don't think about your skin very much on a day to day basis, but it has some very important jobs, including:
- protecting you from infections
- protecting your other organs and muscles from getting hurt when you have small accidents like burns or grazes
- controlling your body temperature (by sweating).
It's made up of 2 layers:
- Epidermis – The tough, waterproof layer that you can see on the surface. These cells are constantly rubbing off and being replaced.
- Dermis – This layer contains the nerves, blood vessels, sweat glands and hair roots.
