Glossary
A skincare ingredient that forms a protective barrier on the skin's surface to prevent moisture loss through evaporation. Beeswax is one of the most effective natural occlusives. Unlike petroleum-based options, beeswax allows the skin to breathe while sealing in hydration.
Your skin is constantly losing water. Through a process called transepidermal water loss (TEWL), moisture evaporates from the deeper layers of the skin through the outer epidermis and into the air. In healthy skin with an intact lipid barrier, TEWL occurs slowly. In damaged, dry, or compromised skin, the rate accelerates, creating a cycle of increasing dryness and irritation.
Occlusives break this cycle by forming a thin, physical film over the skin's surface that slows or prevents water from escaping. Think of it as putting a lid on a pot of simmering water: the moisture stays where it belongs.
The most widely used occlusive in conventional skincare is petrolatum (petroleum jelly). It is extremely effective at reducing TEWL, cutting water loss by up to 98% according to some studies. However, petrolatum is derived from petroleum refining, sits heavily on the skin surface, and does not provide any active nourishment to the skin cells underneath. It locks moisture in, but it does not contribute any of its own.
Beeswax takes a different approach. As a natural occlusive, beeswax reduces TEWL significantly (studies suggest 30-40% reduction, depending on formulation), while also delivering its own beneficial properties. Beeswax contains natural vitamin A, which supports skin cell renewal. It forms a breathable barrier that lets the skin perform its normal functions, including perspiration and thermoregulation, while still protecting against moisture loss.
An occlusive alone is not a complete skincare solution. Sealing in moisture only helps if there is moisture to seal. This is why effective formulations combine occlusives with humectants (which attract moisture) and emollients (which soften and nourish). Our lotion bars use all three: beeswax as the occlusive, coconut oil and shea butter as emollients, and the natural humectant properties of beeswax and residual honey compounds to attract and retain moisture.
For overall skin health, many dermatologists and skincare formulators consider beeswax a superior choice. While petrolatum technically reduces moisture loss more aggressively, beeswax provides a breathable barrier, contributes natural vitamin A, and avoids the petroleum-derived origin that many consumers prefer to avoid.
It depends on the specific occlusive. Heavy petroleum-based occlusives can contribute to pore congestion. Beeswax has a comedogenic rating of 0-2, making it one of the safer occlusive options. For facial use, lighter occlusives or thin beeswax layers in properly formulated products are the safest approach.
Apply products containing occlusives as the last step in your skincare routine, after applying any water-based serums or treatments. The occlusive layer seals in everything underneath. For our solid products like lotion bars, simply apply directly to clean skin, ideally right after a shower when skin is warm and slightly damp.
