What is one of the main functions of a moisturizer?

One of the main functions of a moisturizer is to prevent water loss. Moisturizers are formulated to provide hydration and create a barrier on the skin that locks in moisture. This is essential for maintaining skin elasticity and overall health. When the skin is properly hydrated, it can better resist external aggressors, reducing the chances of dryness and irritation.

The ability to prevent water loss is critical, especially for individuals with dry skin conditions or those exposed to harsh environmental factors. A well-hydrated skin barrier not only looks smoother and plumper but also functions more effectively in protecting the body.

While enhancing fragrance, removing impurities, and providing exfoliation may be beneficial features of certain products, they are not the primary functions of a moisturizer. The primary focus of moisturizers is hydration and the maintenance of moisture levels in the skin.
