The skin has three layers namely:
- Epidermis - the outer most layer of the skin. It is the visible portion that sheds every 28 days. This layer mainly consists of keratin that makes the skin waterproof as well as strong. Melanin is also in the epidermis. It is responsible for our skin tone.
- Dermis - the middle layer that comprise of sweat glands, hair follicles as well as connective tissues. The sensory receptors, which are responsible for the feeling pain or touch, are concentrated in this layer. There are also tiny blood vessels in this layer that supplies the nutrients needed in the skin.
- Hypodermis - is the deepest layer of the skin mainly consisting of fat and connective tissues. This layer functions mainly for insulation.
