What is the main function of occlusive products?

The main function of occlusive products is to reduce transepidermal water loss. These products form a physical barrier on the surface of the skin, which helps to prevent moisture from escaping. This is especially beneficial for individuals with dry or dehydrated skin, as it helps to lock in hydration and maintain the skin's moisture balance. By creating this barrier, occlusive products can effectively support the skin's natural barrier function and improve overall skin hydration.

In contrast, moisturizing products generally serve to hydrate the skin but do not necessarily prevent water loss to the same extent. Exfoliating products are designed to remove dead skin cells from the surface of the skin, and while they can improve texture and cell turnover, they do not create a barrier to minimize water loss. Enhancing blood circulation, while beneficial for overall skin health, is not a primary function of occlusive products and does not directly relate to moisture retention strategies.
