Scanning electron microscopy of skin surface |

Each day the skin suffers multiple attacks, whether physical or mechanical, from undesirable micro-organisms or the sun. Luckily, it withstands these with very sophisticated detection, protection and defence systems in the epidermis and dermis. But that isn't everything. In addition to its protective function,
the skin also has a metabolic function,
and a sensory function.
Finally, in order to play these roles perfectly, it must maintain its integrity by repairing itself. |
