Overview
Your skin is composed of many different layers, with the skin barrier (formally known as the stratum corneum) making up the outermost layer. The state of your skin barrier can have a direct impact on how your skin looks and feels. When the skin barrier is strong and healthy, it can support skin that appears hydrated, radiant and smooth. On the other hand, when it’s impaired, you may notice unwanted skin issues creeping up, such as sensitivity, itching and flaking. In this guide, we’ll explain some essential information about your skin barrier—including common signs of an impaired barrier and simple steps you can take to help restore it.
Facts About a Weakened Skin Barrier
- When functioning properly, the skin barrier helps keep important moisture in your skin and harmful irritants out.
- Many factors can weaken the skin barrier, including certain skin conditions, over-exfoliating, harsh weather conditions and environmental damage from stressors like the sun’s UV rays.
- Skin barrier disruption has been linked to a variety of skin issues, such as dryness, itching, rough patches, irritation and sensitivity.
- To help restore a weakened skin barrier, many dermatologists recommend a gentle skincare routine that includes a fragrance-free cleanser, moisturizer and sunscreen.
