Barrier
Skin barrier basics in waterline language
Barrier talk is about structure and habits, not miracle drops.
What barrier means
Educational derm writing uses barrier to describe how outer layers slow water loss and keep irritants out - a model, not a diagnosis.
Habits that show up in guides
Over-washing and high-fragrance products appear often in barrier discussions. Your clinician knows your skin.
