Skin Barrier

The skin barrier is the outermost layer of the skin, made up of skin cells held together by lipids like ceramides, cholesterol, and fatty acids. It works like a protective wall, locking moisture in while keeping irritants, pollution, and bacteria out. When the barrier is damaged by harsh products, over-exfoliation, dry air, or stress, skin can feel dry, tight, rough, or easily irritated. Repairing it means replenishing lost lipids, restoring hydration, and calming the skin with gentle, nourishing care. A healthy barrier is the foundation of every skin goal, helping skin stay soft, comfortable, and resilient.
