What is the function of a moisturizer in a skincare routine?

1. To cleanse the skin thoroughly

2. To hydrate and protect the skin barrier

3. To remove makeup

4. To exfoliate dead skin cells

The correct answer is: To hydrate and protect the skin barrier

The primary function of a moisturizer in a skincare routine is to hydrate and protect the skin barrier. Moisturizers are formulated with ingredients designed to improve the skin's moisture content, helping to replenish and maintain hydration levels. This is crucial because properly hydrated skin not only looks healthier and more radiant but also performs better in terms of its overall function and resilience against environmental stressors. In addition to providing hydration, moisturizers often contain ingredients that help strengthen and protect the skin’s natural barrier. A well-functioning skin barrier helps to prevent moisture loss and shields the skin from pollutants, irritants, and harmful bacteria. By supporting this barrier, moisturizers play an essential role in maintaining skin health. Other choices, while important aspects of skincare, do not align with the moisturizing function. For instance, cleansing the skin thoroughly is the purpose of cleansers, while removing makeup is the role of makeup removers. Exfoliation is the process of sloughing away dead skin cells, which is typically the job of exfoliants, rather than moisturizers.
