Glow Definition
Occlusive is a term used to describe ingredients or skincare products that form a physical barrier on the skin’s surface to help prevent water loss. Often found in rich moisturizers, face oils, or balms, occlusives are the final step in many glow routines — sealing in hydration from previous layers like serums and creams.
Common occlusive ingredients include petrolatum, lanolin, squalane, and certain plant butters. This final “lock-in” layer plays a key role in supporting the skin barrier — especially in dry climates, overnight routines, or whenever you want to protect the moisture you’ve already added.

Why It Matters
When it comes to glow, hydration alone isn’t enough — it needs staying power. That’s where an occlusive in skincare steps in. After you’ve layered humectants and emollients, occlusives help keep all the goodness from evaporating. Think of them as the final seal: soft, protective, and glow-preserving.
Whether your skin is prone to dryness, lives in a cold climate, or just needs extra support overnight, using an occlusive product can help create the conditions for long-lasting radiance. It’s a quiet but essential layer in routines focused on moisture retention and barrier repair — especially when your glow needs backup.
GLOW TIP Apply your occlusive product as the very last step in your routine — especially at night — to help lock in every layer underneath, from serums to moisturizers. A little goes a long way when glow is your goal.
Why We Love It For Glow
Occlusives are like the nightlight of your skincare routine — they quietly seal in everything you’ve layered with care. While they don’t add visible radiance on their own, they help preserve all the hydration and nourishment that does.
When skin is prone to dryness, flaking, or simply needs a little extra shielding, a good occlusive ensures your glow doesn’t vanish overnight. Occlusives are especially key during colder months, post-actives, or when your skin barrier is feeling a bit compromised — acting as that final protective veil that lets your glow-boosting efforts do their best work uninterrupted.

FAQ
Can I use an occlusive if I have oily or acne-prone skin?
Yes — but choose a non-comedogenic formula and apply it as your final step only where needed (like cheeks or dry patches), rather than all over. Look for lightweight occlusives like squalane or dimethicone instead of heavier petrolatum-based options.
When’s the best time to use an occlusive?
At night, as the final layer of your routine. It helps seal in your skincare — especially after exfoliation or retinoids — and supports skin’s overnight recovery phase.
Do occlusives work well with other products like serums or oils?
They’re designed to lock everything in — not replace other steps. Layer your hydrating serums and oils first, then apply your occlusive to seal in the moisture and prevent overnight transepidermal water loss.
