The skin is the largest organ of our organism and covers the entire body surface.
It consists of three layers with different characteristics and functions:
- The epidermis: it is the outermost layer and acts as a barrier, preventing on the one side the external penetration of water, foreign substances and micro-organisms and on the other side the loss of water and electrolytes from the body.
- The dermis: is mainly characterized by elastin fibers, which ensure the right elasticity to the skin; from collagen fibers, with support and resistance function and the fundamental substance that has a cementing function. Rich in blood vessels and lymphatics the dermis also has nutrition function.
- Hypodermis: is the third and deepest skin layer and serves as an energy reserve and thermal insulation..
