Dehydration (known as Trans Epidermal Water Loss) is the lack of water within the skin as a result of an impaired skin barrier that is not able to retain water. Water passes from inside the skin to the surrounding atmosphere. Damage to the skin will impair the functioning of the epidermis and its ability to retain a good water balance. Causes of an impaired skin barrier can be as a result of genetics, age or lifestyle but more often than not, the leading cause is incorrect choice of harsh products or treatments which disturb the skin’s acid mantle or even injure the skin. The core philosophy of dermaviduals is to keep the skin barrier intact at all times. By firstly repairing your skin barrier with dermaviduals products, dehydration can effectively be relieved and then further supported with products that add moisture to the skin.
