Which skin care product is designed to hydrate the skin?

A moisturizer is specifically formulated to hydrate the skin. Its primary role is to increase the water content of the outer layer of the skin, known as the stratum corneum. Moisturizers work by trapping moisture in the skin and often contain ingredients like humectants, emollients, and occlusives, which help to attract, soften, and seal in moisture. This is essential for maintaining skin elasticity and preventing dryness, making it a vital part of any skincare routine.

In contrast, cleansers are designed to remove dirt, makeup, and impurities from the skin, while exfoliants help in sloughing off dead skin cells to promote a smoother, more radiant complexion. Toners can assist in balancing the skin's pH and may provide hydration, but their primary function is often to refresh and prep the skin for subsequent products in a skincare regimen. Therefore, while other products contribute to overall skin health, the moisturizer is the one explicitly tailored to deliver hydration.
