Know Your Skin Barrier

By Alison Carroll

Your skin barrier is the outermost layer of your skin and the foundation of everything else. It regulates moisture by preventing water loss, keeping skin plump and healthy. It shields against environmental stressors like pollution and bacteria.

When it’s compromised—by weather, products, over-exfoliation, or a lack of nutrient & lipid replenishment—skin becomes dry, reactive, or inflamed. Conditions like dermatitis and rosacea are more likely to surface when the barrier is struggling. 

Signs of a Compromised Barrier

  • Dryness

  • Reactivity

  • Inflammation

  • Breakouts

  • Rosacea flare-ups

  • Dermatitis

True barrier repair means replenishing what’s naturally there: lipids like fatty acids, ceramides, and cholesterol, alongside moisturizing factors like amino acids and minerals. When these are depleted, skin becomes vulnerable. When they’re restored, moisture retention improves, reactivity calms, and the skin becomes more resilient over time.

Signs of a Healthy Barrier

  • Moisture retention

  • Even tone

  • Calm, no redness

  • Resilience

Our Barrier Balm gives your skin what it needs to become more resilient. It replenishes the outermost layer of your skin, aka your skin barrier, with naturally occurring barrier lipids, ceramides, aminos, and fatty acids for skin that feels plump, bouncy, hydrated, and more resilient over time. It’s about replacing what’s being depleted, not just surface-level hydration.
