Ceramides
INCI: CERAMIDE AP, CERAMIDE EOP, CERAMIDE NP, CHOLESTEROL, PHYTOSPHINGOSINE
Type: Lipid barrier repair complex, skin-identical active
Origin: These lipids are typically produced through biotechnology (fermentation) or derived from plant sources to be identical in structure to those naturally found in human skin.
What it does:
Ceramides are ingredients designed to directly repair and replenish the skin's natural barrier. Each component has a specific, synergistic role: Ceramide AP (Ceramide 6 II) and Ceramide NP (Ceramide 3): Fundamental building blocks of the stratum corneum's lipid layers. They restore cohesion and water-holding capacity. Ceramide EOP (Ceramide 1): A unique, long-chain "rivet" ceramide that links lipid layers together, dramatically strengthening the barrier and reducing transepidermal water loss (TEWL). Cholesterol: A essential lipid that modulates the fluidity of the lipid layers and is critical for their proper formation and function. The optimal ratio with ceramides is key to efficacy. Phytosphingosine: A ceramide precursor and bioactive lipid with antimicrobial and anti-inflammatory properties, which also helps stimulate the skin's own ceramide production. Together, these ingredients mimic the skin's natural mortar to rebuild barrier integrity, lock in hydration, and improve resilience.
Why we use it:
We employ a ceramide complex as a cornerstone of our night repair cream. We include it to deliver targeted, evidence-based barrier therapy. It works while you sleep to actively repair compromised skin, fortify against future stressors, and create the foundation for healthy, hydrated, and calm skin. Scientific basis: Ceramides' efficacy is grounded in the foundational "Brick and Mortar" model of skin barrier science. Clinical studies show a mixture of ceramides, cholesterol, and fatty acids in the correct ratio is superior for barrier repair than any single lipid. Concentration and ratio: We use this complex at an effective concentration ( 1.5% ) where the components are present in a ratio designed to optimally support skin recovery.
