Alhydran is a medical cream used when the skin barrier is disrupted. After cosmetic and/or surgical procedures, you see that the skin barrier is disrupted because there has been “trauma” to the skin.
When the skin barrier is disrupted, the skin loses a lot of moisture, making the skin feel very dry. This can be accompanied by skin irritation, redness and itching.
A good and healthy skin barrier is important to protect the skin from external harmful substances. Also, a good skin barrier ensures that Trans Epidermal Water Loss (TEWL) has a stable level. TEWL also refers to how much water goes out of the body through the skin.
In healthy skin, the superficial skin layer contains about 30% water. This level is important for the skin to function.
With a disrupted skin barrier, the TEWL does not have a stable level. Thus, the body loses a lot of water through the skin. In the epidermis (superficial layer of skin), the water percentage will decrease.
Due to the disrupted skin barrier, the skin is unable to heal and protect itself. Complaints such as itching, redness and dry skin can occur. Thus, proper hydration of the epidermis is important for healing.
