What does the term "occlusive" refer to in skin care products?

The term "occlusive" in skin care products specifically refers to ingredients or formulations that create a physical barrier on the skin, preventing moisture loss. This characteristic is essential for maintaining hydration, especially for individuals with dry or dehydrated skin, as it helps to trap water and oils within the skin’s surface.

Products that are classified as occlusive typically contain heavier oils, waxes, or silicones, which form a protective layer that can help enhance the overall moisture retention of the skin. This is particularly beneficial in situations where the skin is exposed to harsh environmental conditions or excessive humidity, as it minimizes trans-epidermal water loss.

In contrast, other choices focus on different actions related to skin treatment. For example, products containing alpha hydroxy acids are geared towards exfoliation and cellular turnover rather than moisture retention. Additionally, those that enhance cellular turnover do not necessarily behave as occlusives, and products meant to add color to the skin do not relate to moisture retention or barrier formation. Hence, the definition of "occlusive" is specifically tied to the formulation's ability to create a barrier and prevent moisture loss.
