A moisturizer plays a vital role in skincare, primarily aimed at hydrating and protecting the skin barrier. Hydration is crucial for maintaining skin elasticity, preventing dryness, and ensuring the skin looks healthy and plump. The skin barrier, which consists of lipids and cells, acts as the first line of defense against environmental aggressors, allergens, and moisture loss. When a moisturizer is applied, it can provide both immediate surface hydration and long-lasting hydration by preventing transepidermal water loss, thereby supporting the overall health and resilience of the skin.

In contrast to the other options, removing dead skin cells is a function of exfoliation rather than moisturizing. The role of enhancing the effectiveness of cleansers pertains more to the cleansing agent itself than to the moisturizing process. Preparing the skin for exfoliation is a separate aspect of skincare tailored towards optimizing results from exfoliation techniques, but it does not relate directly to the core purpose of a moisturizer. Therefore, the key function of a moisturizer remains centered on hydration and protecting the skin's barrier.
