General facts about skin :

- Human skin consists of 3 main layers;
- upper epidermis
- middle dermis &
- lower sub-cutaneous tissue
- The epidermis is mainly composed of keratinocytes and is 0.4-1.5mm in thickness. It is formed by division of cells in the basal layer which move outwards forming upper layers. The cellular progression from the basal layer to the skin surface takes about 30 days.
