Define the term "occlusive."

The term "occlusive" refers to products that create a barrier on the skin, which helps to prevent moisture loss. These products are typically thicker in consistency and form a protective layer that locks in hydration, making them particularly beneficial for individuals with dry or dehydrated skin. By sealing in moisture, occlusives can enhance skin hydration and contribute to a smoother and healthier appearance.

In contrast, products that cleanse the skin deeply focus on removing impurities and excess oils, which is not the primary function of occlusives. Exfoliating products are designed to slough off dead skin cells, improving skin texture, but they do not serve to create a barrier. Similarly, products that aim to improve skin tone may contain active ingredients targeting pigmentation issues but do not provide the moisture-retaining benefits characteristic of occlusives. Therefore, the definition of "occlusive" aligns clearly with the ability to prevent moisture loss through barrier formation.
