The primary role of moisturizers in skincare is to hydrate, protect, and nourish the skin. Moisturizers are formulated to increase the water content of the skin, which helps maintain its suppleness and elasticity. By providing hydration, they help to prevent dryness and flakiness, creating a smoother and more radiant appearance.

Furthermore, many moisturizers also contain ingredients that form a barrier on the skin's surface, protecting it from environmental factors such as pollution and harsh weather conditions. This barrier function is crucial for maintaining the skin's overall health. Additionally, moisturizers often include nourishing elements like vitamins and antioxidants that support skin health and repair, contributing to a more youthful look.

The cleansing role is associated with products specifically designed to remove dirt and impurities, while exfoliation involves the removal of dead skin cells, which is not the purpose of a moisturizer. Sun protection is addressed through products with SPF, but it falls outside the primary function of moisturizers. Thus, the correct answer emphasizes the comprehensive role that moisturizers play in skincare by hydrating, protecting, and nourishing the skin.
