Skincare Guide - Occlusive Agents
Occlusive active ingredients – protective film and moisture for the skin
Occlusive agents form a fine protective layer on the skin, preventing moisture from evaporating. They are considered a key component for dry, sensitive, or barrier-impaired skin, as they promote regeneration and keep the skin supple.
What does "occlusive" mean?
The term occlusive comes from the Latin "occludere" – "to close." In skincare, it describes substances that act like a protective film and reduce transepidermal water loss (TEWL). According to CeraVe Germany (2025), occlusive ingredients are particularly helpful in stabilizing the skin's natural barrier in cases of dryness or irritation.
How do occlusive substances work?
They lock in moisture without completely sealing the skin. This keeps it more elastic and resilient. Dermaviduals (2024) describes how controlled occlusion promotes the recovery of the stratum corneum, thus improving the skin's resilience – especially in cases of barrier dysfunction.
Typical occlusive ingredients
- Petrolatum: A proven active ingredient in medical care with a strong moisturizing effect.
- Lanolin: Natural wool wax that replenishes lipids and makes skin supple.
- Plant waxes: Carnauba and candelilla wax form gentle, breathable protective films.
- Squalane: A skin-identical lipid with a mild occlusive effect, ideal for sensitive skin.
Advantages and potential limitations
Occlusive skincare protects the skin from dehydration and irritants. According to the NDR guide (2024), it is particularly suitable during cold months or when the skin is under considerable stress. It should be used selectively on oily or blemished skin to prevent heat build-up and clogged pores.
Modern formulations
Modern cosmetics combine occlusive, moisturizing, and nourishing components. NATURFACTOR®'s Bioactive Infusion Complex™ utilizes plant-based lipids and amino acids to support the skin's natural protective barrier – without weighing it down or sealing it off.
Suitable for which skin types.
Especially for dry, sensitive, or barrier-impaired skin, occlusive agents noticeably improve the skin's feel. They help smooth cracks and restore the skin's natural protective barrier.
Conclusion
Occlusive agents are essential for a strong and resilient skin barrier. They retain moisture, protect against environmental influences, and leave the skin soft and smooth. With modern, skin-friendly lipid formulations like the Bioactive Infusion Complex™ , NATURFACTOR® redefines the concept of occlusion – as a nourishing, breathable protective film.
