Skin barrier function
The skin barrier is the outermost layer of your skin that acts as a protective shield. It prevents harmful things like bacteria, pollutants, and irritants from entering your body, while also keeping essential moisture inside. This barrier is made up of dead skin cells and oils that work together to maintain hydration and defense. When the barrier is healthy, your skin feels smooth, resilient, and less prone to irritation. Damage or imbalance can lead to dryness, redness, or increased sensitivity, emphasizing the importance of caring for and supporting this vital protective layer.
