Occlusives
Occlusives are substances used in skincare that create a barrier on the skin's surface. This barrier helps to lock in moisture and prevent water loss, making them particularly beneficial for dry or dehydrated skin. Common occlusives include ingredients like petrolatum, beeswax, and shea butter.
These ingredients work by forming a protective layer that can also shield the skin from environmental factors. While occlusives are effective for hydration, they may not be suitable for everyone, especially those with oily or acne-prone skin, as they can potentially clog pores.
