Occlusives
What they do. Occlusives work “by slowing the evaporation of water from the surface of the skin,” notes Dr. Brannon. They form a thick barrier film over skin’s outer layers to prevent moisture from evaporating. Occlusives work best when they’re applied to damp skin. Unfortunately, occlusive ingredients can be greasy or sticky. And they can clog pores, contributing to acne. So, unless you have super-dry skin on your face and you rarely break out, you might want to consider these ingredients for use on your body only.
Examples. Beeswax, caprylic/capric triglycerides, cyclomethicone, hydrogenated castor oil, mineral oil, lanolin, petroleum, petrolatum, silicone, dimethicone and vegetable oils (like avocado or olive oil).
