What is the effect of using occlusive products?

Using occlusive products effectively creates a barrier on the skin's surface that helps to retain moisture. This is particularly beneficial for individuals with dry or dehydrated skin, as it minimizes transepidermal water loss. By sealing in hydration, these products prevent the water content of the skin from evaporating into the environment, leading to improved skin hydration and overall skin barrier function.

Occlusive agents like petrolatum, mineral oil, and certain waxes are commonly found in various skincare formulations. When applied, they can provide a protective layer that allows moisture to accumulate and helps in repairing and maintaining the skin's natural barrier. This is crucial for overall skin health, especially in harsh climates or during dry seasons.

While other options may have their own benefits, the specific action of occlusion is to lock in moisture, making the retention of hydration the primary effect of these types of products.
