Dry and dehydrated skin is not the same, however they share the same look. Namely, this is a skin with rough texture, lack of elasticity, shrunk and flaking with no ability to reproduce keratin cells.
In dehydrated skin, its water content has been reduced
In dry skin, lipids required for water retention have been decreased.
Dried skin is not necessarily dry, because oily skin can become dried too.
Many factors can contribute to skin dryness:
- Individual factors such as excessive washing or use of detergents resulting in the removal of skin lipids and inability to retain water from the keratin layer.
- Individual habits such as the consumption of alcohol and smoking.
- Environmental factors. Such as the sun, environmental pollution and air conditioning.
- Medical factors. Such as local application or habitual ingestion of medicine e.g. isotretinoin, enteric diseases with regular defecations.
- Age. As time goes by, skin deteriorates and its reproduction rate decelerates resulting in disorders with regard to the structure and function of the skin.
