    The skin, the largest organ of the human body, measures two square metres in size. However, when we think of the most important organs, we always think of the heart or brain, overlooking this fine sheath that completely encloses us. The skin is our main barrier against external agents, preventing viruses, harmful bacteria and mites from entering our bodies. Read More
