Barrier products are designed to do what for the skin?

Barrier products are specifically formulated to seal the surface of the skin and hold moisture in. This function is crucial for maintaining hydration, as the skin can easily lose water through evaporation, especially in dry or harsh environmental conditions. By forming a protective layer, these products help to prevent moisture loss, keeping the skin hydrated and more comfortable. This is particularly important for those with dry skin or individuals exposed to elements that can cause skin barrier disruption.

In contrast, other options serve different purposes. Increasing elasticity typically involves ingredients that can promote collagen production or improve skin's structural integrity. Exfoliating dead skin focuses on removing the outermost layer of dead skin cells, which is essential for skin renewal and texture improvement. Providing a fragrant aroma is not related to the primary function of barrier products, which is centered around protection and hydration rather than fragrance.
