What is the Skin Barrier?
Your skin barrier, also known as the stratum corneum, is the outermost layer of your skin. Think of it as a protective shield made up of skin cells held together by lipids. Its primary functions include:
1. Keeping moisture in: It locks in hydration, ensuring your skin stays soft and supple.
2. Keeping irritants out: It acts as a barrier against environmental aggressors, bacteria, and pollutants.
When the skin barrier is healthy, your skin appears smooth, hydrated, and glowing. However, winter’s harsh conditions can compromise this shield, leading to a host of problems.
