Epidermal barrier: What it is, why its role matters, and how to keep it healthy

In recent years in the world of beauty we often refer to the term “epidermal barrier”. So we decided to put together a little guide to clarify: what it is, why its role is so important and how we can keep it healthy.

What is the skin barrier?

The term “skin barrier” refers to the outer layer of the skin called the stratum corneum. The main function of the stratum corneum is to protect the skin from environmental stressors, free radical damage, toxins and pathogens. However, the epidermal barrier also consists of layers:

  • The microbiome
  • The acid mantle
  • The lipid barrier
  • The Skin

The acid mantle is often considered the chemical line of defense and the lipid barrier is the physical line of defense. This is because in the former, sebum plus amino acids help keep the pH on the acidic side to kill pathogens. The latter consists mainly of cholesterol, fatty acids and ceramides that help maintain skin moisture.

Why is a healthy skin barrier so important?

The skin barrier is strong, but that doesn’t mean it doesn’t need help. Maintaining good health is extremely important as this is one of the body’s first lines of defense. During the day, the body is in a state of defense, constantly protecting your skin from possible environmental damage. Ensuring that the skin is prepared minimizes any potential future skin damage.

How can you recognize if the skin barrier has been disrupted?

A disrupted or damaged epidermal barrier manifests differently from person to person. The most important thing is to take care of your skin. If it feels too dry or too oily, take that into account and adjust the products you use accordingly. If the problem persists, seek the help of your dermatologist.

Tips for restoring your skin barrier:

  • Listen to your skin. Don’t get stuck in a rigid routine. Your needs come first.
  • Focus on nutritious products that perfectly hydrate the skin. Even if your skin is oily, remember that proper hydration is extremely important.
