Okkluzívokkal

Okkluzívokkal, also known as occlusives, are a class of ingredients commonly found in skincare and cosmetic products. Their primary function is to create a physical barrier on the surface of the skin. This barrier helps to prevent transepidermal water loss (TEWL), which is the evaporation of water from the skin into the environment. By reducing water loss, occlusive ingredients contribute to improved skin hydration and can help to maintain the skin's natural moisture barrier.

These ingredients work by forming a film on the skin's surface. This film is not readily absorbed into the skin but rather sits on top, effectively sealing in moisture. This makes them particularly beneficial for dry, dehydrated, or compromised skin conditions. They can also help to protect the skin from external irritants and environmental stressors.

Common examples of occlusive ingredients include petrolatum (petroleum jelly), mineral oil, dimethicone, lanolin, and various waxes such as beeswax. While effective, the occlusive nature of these ingredients means they can sometimes feel heavy or greasy on the skin, depending on the specific ingredient and its concentration. For individuals prone to acne or clogged pores, some heavier occlusives might be avoided, although lighter silicone-based occlusives like dimethicone are often well-tolerated. Their use is widespread in moisturizers, ointments, balms, and protective creams.
