What are occlusive agents in skincare?

Occlusive agents in skincare are substances that create a barrier on the skin's surface, effectively preventing moisture loss. These ingredients work by sealing in hydration and providing a protective layer, which is particularly beneficial for individuals with dry or dehydrated skin. By minimizing transepidermal water loss, occlusives help to maintain skin hydration and improve its overall barrier function.

This functional characteristic is integral to many skincare routines, especially in products designed for hydration and protection. While other ingredients may serve different purposes, such as enhancing absorption or exfoliating the skin, occlusives specifically focus on retaining moisture, making them essential for maintaining skin's moisture content and overall health.
