Glow Definition
Squalane in skincare is a lightweight, stable oil commonly used as a replenishing emollient. It’s a hydrogenated derivative of squalene (with an “e”), a lipid naturally found in the skin’s sebum, but squalane is more shelf-stable and widely favored in cosmetic formulas. Because it mimics skin’s own oils, it layers easily without a greasy feel — making it a popular choice in moisturizers, face oils, and hydration-focused routines.
Originally derived from shark liver, most modern squalane is now sustainably sourced from plants like olives, sugarcane, or rice bran. It functions primarily to soften and support the skin’s moisture barrier, often serving as the final occlusive layer in a routine. You’ll see it in both minimal routines and more layered formats, especially when seeking that dewy, non-disruptive finish.

Why It Matters
Squalane in skincare plays a supportive role in routines that prioritize barrier health, especially when skin feels dry, depleted, or out of sync. Because it’s lightweight and biocompatible, it can help reinforce moisture without creating heaviness — making it a favorite in both minimalist and multi-step lineups.
Its real strength lies in its adaptability. Squalane works well across a range of routines, whether layered over humectants like glycerin, paired with emollients, or added as a final step to help seal in hydration. For glow seekers, it’s often the quiet finisher — the thing that adds slip, comfort, and a subtle cushion without taking center stage.
GLOW TIP Don’t underestimate the final layer — pressing a few drops of squalane over damp skin can turn hydration into lasting comfort.
Why We Love It For Glow
Squalane quietly earns its spot as a glow essential by doing what many actives don’t — supporting without overwhelming. Its featherlight texture makes it versatile across seasons and routines, slipping in wherever a little extra suppleness is needed. It layers effortlessly over hydrating serums or under richer creams — always adapting, never demanding.
We especially love squalane’s role in grounding a routine. When everything else is working to brighten, correct, or refine, squalane simply cushions — adding softness and staying power to your glow without the noise.

FAQ
Is squalane good for sensitive skin?
Yes — squalane is often included in routines built for sensitive skin because of its lightweight, non-disruptive texture. It offers a cushion of moisture without introducing heavy or reactive ingredients, making it a quiet staple in minimalist and barrier-focused routines.
What’s the difference between squalene and squalane?
Squalene (with an “e”) is the natural lipid our skin produces, but it’s known to be unstable in cosmetic formulas. Squalane (with an “a”) is its more stable, hydrogenated version — used in skincare for its ability to mimic the skin’s own oils while offering a longer shelf life and smoother application.
Where does squalane fit in your skincare routine?
Squalane typically works best as a final or near-final step in your routine. It’s often layered over hydrating serums and creams to help seal everything in, especially at night or in drier climates where moisture loss is more likely.
