When seeking out skincare products that contain occlusives, it is crucial to examine the ingredient labels thoroughly. Look for specific ingredients such as petrolatum, petroleum jelly, mineral oil, beeswax, paraffin, squalene, dimethicone, lanolin, capric triglyceride, carnauba wax, and shea butter. These substances are known for their occlusive properties, which help to create a protective barrier on the skin to lock in moisture and prevent water loss.
