- The epidermis hosts cells that produce melanin; the substance that gives your skin its color.
- Your epidermis controls the outside appearance of your skin and helps to you to retain moisture.
- The dermis is the second layer of your skin, it contains the proteins elastin and collagen; this is where damage occurs and also thins with age.

- The nerves and receptors in the dermis send you pain signals when you cut yourself.
