Barrier Function

Barrier function refers to the skin’s natural defense system, primarily governed by the stratum corneum and its lipid matrix. It prevents transepidermal water loss (TEWL) and keeps out environmental stressors like pollutants, microbes, and irritants. In AgeBiome™ rituals, protecting and repairing barrier function is central to ensuring safe, effective delivery of actives and long-term skin resilience.

Why It’s Used:

• Prevents dryness, irritation, and inflammation
• Supports biome balance and microbial diversity
• Essential for recovery after exfoliation or device use
• Helps retain hydration and nutrient absorption
• Enhances skin’s tolerance to active ingredients
• Repaired using ceramides, peptides, and calming botanicals

What It Means for You:‍

Your skin’s barrier is what keeps everything in and out—moisture in, stress out. AgeBiome™ works with your barrier, not against it, so you get results without reactivity.
