The skin barrier (more precisely, the stratum corneum) is the outermost layer of the epidermis, made of compacted skin cells and lipids. When it’s intact, it:
• Keeps moisture in → preventing dryness and dehydration
• Keeps irritants and pathogens out → reducing sensitivity and infection risk
• Regulates permeability → allowing certain beneficial molecules (like skincare actives) to pe*****te in a controlled way
Signs your barrier is likely intact include:
• Smooth texture
• Even tone
• No persistent redness or flaking
• Minimal sensitivity
Signs of a compromised barrier include:
• Increased redness or stinging from mild products
• Rough patches or peeling
• Sudden breakouts or inflammation
Here’s how it supports the barrier:
1. Lipid Replenishment
• Epicutis Lipid Serum contains patented TSC (Tetramethylhexadecenyl succinoyl cysteine), which is an anti-inflammatory antioxidant that calms skin while reducing oxidative stress.
2. Anti-Inflammatory Protection
• Many barrier issues start with inflammation (from UV, pollution, over-exfoliation).
• Epicutis uses pharma-grade, clinically tested anti-inflammatory molecules (like TSC and Hyaluronic Acid) to stop the “silent” irritation that keeps the barrier from healing.
3. Hydration Without Irritation
• Hydration comes from glycerin, sodium hyaluronate, and biomimetic lipids, which pull water in while sealing it with a lipid shield — mimicking a naturally intact barrier.
4. pH & Microbiome Support
• Products are formulated at a skin-friendly pH (around 5–5.5), which supports the skin’s acid mantle — a key component of the barrier.
• Some products, like the Hydrobiome Mist, include prebiotics to feed good bacteria, which act as a living part of your skin’s defense.
5. Medical-Grade Formulation Philosophy
• Avoid products with unnecessary fillers, keeping formulas extremely short and purposeful.
• Fewer irritants + higher active concentrations = faster barrier recovery.
