Understanding Sensitive Skin and the Skin Barrier

This discussion centers on the importance of maintaining a healthy skin barrier, particularly for individuals with sensitive skin. It is part of an educational series focused on evidence-based practices for cleansing and moisturizing. The conversation emphasizes that skin care—especially how the skin is cleansed and moisturized—is essential to promoting barrier repair and achieving better dermatologic outcomes.

The skin barrier is described as a protective shield for the body. When intact, it helps retain moisture and prevents irritants from entering. However, when the barrier is disrupted, it can lead to water loss, dryness, irritation, and even inflammation. Maintaining this barrier is considered a medical necessity rather than a cosmetic choice, especially for those dealing with sensitive or compromised skin.

Cleansers and moisturizers play a vital role in supporting skin health. Harsh cleansers can strip the skin of its natural oils and worsen symptoms in sensitive individuals. Instead, gentle, pH-balanced cleansers are recommended to help maintain the skin’s integrity. These practices are fundamental to preventing skin issues and supporting overall dermatologic health through everyday routines.
