How Barrier Protection Works – Ceramide Complex Explained

Scientific breakdown for Dermatologists, Enthusiasts & Beginners | By Epidora Skincare

Section 1: For Dermatologists & Professionals

The stratum corneum (SC) functions as a permeability barrier, protecting against TEWL and external aggressors. This barrier is structurally dependent on a lipid matrix composed of approximately 50% ceramides, 25% cholesterol, and 15% free fatty acids.

Ceramide Complex – Composition & Role

  • Includes Ceramide NP, AP, EOP, Phytosphingosine, and Cholesterol
  • Rebuilds lamellar structures and reduces inflammation markers
  • Restores corneocyte cohesion and homeostasis

Clinical Evidence

  • Proksch et al., 2008: 50–60% TEWL reduction in atopic skin
  • Rawlings, 2010: Enhanced keratinocyte differentiation and lipid regulation

Section 2: For Enthusiasts

Ceramides are the skin's natural lipids. They're like mortar between bricks (cells). When you lose them, your skin barrier gets "leaky."

Benefits of Ceramide Complex

  • Restores hydration and elasticity
  • Reduces irritation and breakouts
  • Helps skin recover from acids, actives, or harsh weather
  • Preps skin for stronger ingredients

Section 3: For Starters

Your skin has a shield—your barrier. When that shield breaks, you feel dryness, itching, and more breakouts.

Ceramide Complex helps your skin "glue" itself back together. It keeps hydration in and bad stuff out.

What You’ll Notice:

  • Softer skin
  • Less dryness
  • Calmer skin after using active ingredients
