5 Tips to Repair Skin Barrier Damage: Beginner's Guide

The skin is the largest organ of your body, and it's also one of the most important. The health of your skin impacts everything from how you look to how healthy you feel. If you're experiencing dryness, itching or redness, then you've probably got a problem with your skin barrier—the outermost layer of skin that keeps moisture in and germs out. This guide will help you understand skin barrier function and how to repair skin barrier damage.
What is skin barrier?
The skin is made up of three layers
-
The epidermis or outer thin layer
-
The dermis, or thick middle layer
-
The subcutaneous fatty layer
The epidermis and its upper layer, the stratum corneum, is your body's first line of defense and acts as a skin barrier. Its purpose is to protect the body from infection, moisture loss, and physical injury. Under a microscope, the stratum corneum consists of tiny cells called corneocytes that act as bricks and are tightly glued together by ceramides, cholesterol, and fatty acids. This layer also contains a protein called filaggrin which makes natural moisturizing factors (NMF) for the skin.
A healthy barrier will keep your body hydrated by preventing excessive water loss through evaporation. In addition to preserving hydration levels within its confines, this outermost layer also shields us against germs like bacteria or viruses by creating an extra layer between them.
Quick facts about skin barrier

What is skin barrier damage?
The skin barrier, also called the moisture barrier or acid mantle, has two functions: keep the good stuff in and the bad stuff out. The skin barrier protects the internal body from pollution, harmful chemicals, and ultraviolet radiation from sun exposure. It also helps keep the body's moisture level intact; however, when the outermost layer of the epidermis (the stratum corneum) doesn't contain enough moisture, the skin will lose elasticity and appear dry, rough and flaky. It will prevent it from maintaining an appropriate skin barrier leaving the skin exposed and vulnerable to damage from external and environmental sources
