Skin Barrier
The outermost protective layer of the skin (stratum corneum) that regulates moisture and protects against irritants.
What It Is
The skin barrier is the outermost layer of the skin, called the stratum corneum. It's made up of dead skin cells and natural oils that work together to keep moisture in and protect against things that might irritate the skin, like harsh chemicals or extreme temperatures.
How It Works
The skin barrier works by creating a physical barrier that prevents moisture from escaping and keeps irritants out. It's also dynamic, meaning it can repair itself if damaged. In skincare research, scientists often study the skin barrier to understand how to keep it healthy and functioning properly.
Why It Matters
Understanding the skin barrier is crucial for skincare research because it plays a key role in how our skin looks and feels. By studying the skin barrier, scientists can develop new treatments and products that help maintain its health and function.
