Skin Barrier
What is it?
The skin barrier, or stratum corneum, is the outermost layer of the skin that serves as a protective shield. It consists of skin cells held together by lipids, preventing water loss and protecting against environmental aggressors such as pollution, irritants, and microbes.
What can it do?
A compromised skin barrier may appear as redness, dryness, sensitivity, or breakouts. Common causes include over-exfoliation, harsh cleansers, and environmental factors like cold weather or pollution.
Restoring the skin barrier requires focusing on hydration and nourishment. Ingredients like ceramides, fatty acids, and hyaluronic acid support repair. Gentle cleansing and avoiding drying or irritating products are also important for recovery.
A healthy skin barrier is crucial not only for overall skin health but also for the effectiveness of other skincare products. Maintaining it is the foundation of a successful skincare routine.
