The two main functions of the epidermis (or the skin) are:
1) A barrier against pathogens and toxins.
- The epidermis acts as a physical barrier but also as a chemical barrier due to the presence of lipids and acids which work to destroy certain pathogens.
2) Hydration
- The skin holds a large percentage of water and lipids arranged within the epidermis act as a barrier to prevent water loss from the body.
Epidermal cell helps in protection, absoption and gaseous exchange.
