What is the primary function of occlusive products?

The primary function of occlusive products is to reduce transepidermal water loss. These products create a physical barrier on the skin's surface, which helps to lock in moisture and prevent water from escaping. This is particularly important for maintaining hydration, especially in environments that may promote dryness, such as low humidity or exposure to wind.

Occlusive agents can include ingredients like petroleum jelly, waxes, or oils, which are effective at providing this barrier effect. By minimizing water loss, these products can help maintain the skin's hydration levels, improve its overall texture, and support its natural barrier function.

Other functions, such as exfoliating dead skin cells or enhancing color, do not align with what occlusive products are designed to do. These other actions typically involve different types of products or ingredients, such as exfoliants for skin shedding or color-enhancing products for improving skin tone. Thus, the fundamental role of occlusive products in skincare is centered on moisture retention and maintaining skin hydration.
