If you've ever struggled with redness, dryness, irritation, or breakouts that seem to appear out of nowhere, your skin barrier might be trying to tell you something.

What Is Your Skin Barrier?

Your skin barrier—also known as the stratum corneum—is your body’s first line of defense. It keeps moisture in, blocks environmental stressors out, and helps maintain overall skin function. When this barrier is healthy, your skin looks and feels balanced, hydrated, and strong.

But when it’s compromised? Cue inflammation, breakouts, sensitivity, and more.

Why Does the Skin Barrier Break Down?

Several factors can lead to a weakened skin barrier:

• Over-exfoliation

• Harsh products or fragrances

• Environmental stress (pollution, UV)

• Lifestyle stress (travel, workouts, hormones)

How TRNR Skin Helps Repair and Strengthen It

And because all of our products are dermatologist-developed and plant-based, they avoid common irritants and focus on what your skin actually needs.
