Ceramides are essential lipids naturally present in the skin's outer layer, forming a protective barrier that retains moisture and shields against environmental damage. Topical application replenishes these lipids, restoring skin barrier integrity and improving hydration. This supports skin health by reducing vulnerability to irritants and inflammation, which are factors in accelerated skin aging and overall systemic stress.
Verdict
Strengthens skin barrier, boosts hydration, supports dermal resilience.
