Can dehydrated skin cause a compromised or weakened skin barrier?
Short answer: Yes.
Detailed answer
Dehydrated skin can cause a compromised or weakened skin barrier. When the skin lacks proper hydration, it can lead to a decrease in the production of natural moisturizing factors (NMFs) and lipids, which are essential for maintaining a healthy skin barrier. This can result in increased transepidermal water loss (TEWL) and decreased ability to retain moisture, making the skin more susceptible to irritants, pollutants, and environmental damage. Additionally, a compromised skin barrier can lead to increased sensitivity, redness, inflammation, and a higher risk of skin conditions such as eczema and dermatitis. It is important to keep the skin adequately hydrated to support a strong and healthy skin barrier.
