Which effect do occlusive agents in moisturizers provide?

Occlusive agents in moisturizers are designed primarily to create a barrier on the skin’s surface. This barrier plays a crucial role in preventing transepidermal water loss, which is the evaporation of moisture from the skin to the environment. By forming a protective layer, occlusive agents help to lock in hydration and maintain the skin's moisture levels, promoting skin health and improving its overall texture and appearance.

While exfoliation and surface cleansing involve removing dead skin cells and impurities, respectively, these activities are not functions of occlusive agents. Similarly, while some skincare products may have antimicrobial properties, this is not related to the primary purpose of occlusive agents. They are specifically formulated to enhance moisture retention, making them essential for individuals dealing with dry or dehydrated skin.
