'At the heart of healthy skin lies the skin barrier, also known as the 'moisture barrier.' This complex system of lipids, proteins, and cells plays several crucial roles in skin health.
Skin barrier protects moisture and shields against pollution, UV rays, and pathogens, it also blocks external threats. Skin damage is more likely without a strong barrier. The skin barrier keeps bacteria at bay and promotes skin health with a slightly acidic pH. It prevents irritants and allergens from penetrating the skin, reducing redness and inflammation.
Fun fact: The stratum corneum is the outermost skin barrier layer. Lipids and dead skin cells form a thin protective barrier.
