What is the term for products that are thick and lay on top of the skin to reduce transepidermal water loss?

The term for products that are thick and lay on top of the skin to reduce transepidermal water loss is occlusive. These products create a barrier on the surface of the skin, which effectively prevents moisture from escaping into the environment. By forming this protective layer, occlusive agents help retain hydration, making them particularly beneficial for individuals with dry or compromised skin.

Unlike hydrating products, which typically add moisture to the skin, or exfoliating products, designed to remove dead skin cells, occlusives focus specifically on minimizing water loss. Emollients, while they do soften and smooth the skin, may not necessarily provide the same level of barrier against transepidermal water loss as occlusive products do. Understanding the role of occlusives is essential for effective skincare, especially when aiming to maintain skin hydration.
