The Science of Skin Barriers

Why the Skin Barrier Matters

Your skin is more than just what you see in the mirror. It’s your body’s largest organ and your first line of defense against the outside world. The outer layer, known as the skin barrier or stratum corneum, works like a finely tuned shield. It holds in essential moisture, blocks out harmful irritants, and helps keep the balance your skin needs to stay healthy.

When your skin barrier is strong, it locks in hydration, keeps your complexion smooth, and protects against everyday environmental stressors. When it’s weakened from harsh products, over-exfoliation, or environmental pressure, you’ll start to notice dryness, redness, irritation, and sensitivity. For those living with Alpha-gal Syndrome or other skin sensitivities, protecting this barrier isn’t just about beauty, it’s about comfort and health.
