What Is Squalane? The Face Oil That Actually Works for Every Skin Type — Including Oily
Squalane at a glance
What it is
A saturated hydrocarbon derived from squalene (a natural lipid in human sebum). Modern squalane comes from olive oil or sugarcane — completely vegan and sustainable.
What it does
Emollient and occlusive — softens skin, reduces transepidermal water loss, and mimics the skin’s own natural lipids. Non-comedogenic with a comedogenicity rating of 0–1.
Who should use it
Virtually everyone — including oily skin, acne-prone skin, and sensitive skin. Its non-comedogenic rating and skin-identical chemistry make it uniquely universally tolerated.
When to use it
PM routine as a final sealing step. Can also be mixed into moisturiser for extra nourishment. No photosensitivity — safe for AM use too, though PM is more impactful.
Key advantage over other oils
Comedogenicity rating of 0–1 vs most face oils at 2–4. Even acne-prone and oily skin types can use squalane without risk of clogged pores.
Source matters
Historically from shark liver (avoid). Now ethically sourced from sugarcane or olive-derived hydrogenation. Always check source — look for “plant-derived” on the label.
Squalane is the face oil that broke the rules of face oils. Most facial oils are contraindicated for oily or acne-prone skin — their comedogenicity ratings mean they clog pores and worsen breakouts. Squalane’s comedogenicity rating of 0–1 means it sits on the skin, reinforces the barrier, and reduces water loss without ever entering or blocking a pore. This makes it uniquely appropriate for the skin type that conventional wisdom says should avoid oils entirely.
Understanding why squalane works differently from other oils requires understanding the chemistry — specifically the difference between squalene (the natural molecule) and squalane (the stable, usable skincare ingredient derived from it).
Squalene vs Squalane — Why the Difference Matters
❌ Squalene (the natural form — unstable)
Squalene is a naturally occurring lipid found in human sebum (comprising about 12% of it). It’s also found in shark liver oil, olive oil, and sugarcane. In its natural form, squalene is highly unstable — it oxidises rapidly on exposure to air and light, forming comedogenic peroxides that clog pores. This is why you can’t use raw squalene in skincare — oxidised squalene is actually pro-acne.
✅ Squalane (the skincare ingredient — stable)
Squalane is produced by hydrogenating squalene — adding hydrogen atoms to saturate the double bonds that make squalene unstable. This creates a completely stable molecule that doesn’t oxidise, doesn’t go rancid, and doesn’t form comedogenic peroxides. Stable squalane mimics the skin’s natural squalene without any of the instability issues. It’s this stability that makes squalane uniquely non-comedogenic.
Why Squalane Works Even for Oily Skin — The Comedogenicity Scale
| Oil | Comedogenicity Rating (0–5) | Verdict for Acne-Prone Skin |
|---|---|---|
| Squalane | 0–1 — Non-comedogenic | ✅ Safe for all skin types including acne-prone and oily |
| Argan oil | 0 — Non-comedogenic | ✅ Safe — another good option |
| Rosehip oil | 1 — Very low | ✅ Generally safe for most skin types |
| Jojoba oil | 2 — Low | ⚠️ Generally fine but may trigger sensitivity for some |
| Coconut oil | 4 — High | ❌ High risk for acne-prone skin — avoid on face |
| Wheat germ oil | 5 — Very high | ❌ Avoid entirely on face — highly comedogenic |
| Vitamin E oil (pure) | 4–5 — Very high | ❌ Pure application comedogenic — use in formulas only |
4 Ways to Use Squalane in Your Routine
As a standalone facial oil — PM last step
The most common use: 3–5 drops pressed into skin as the absolute final PM step, after all other products. Squalane creates a thin occlusive layer that slows transepidermal water loss overnight without blocking pores. The skin absorbs it without the greasy residue associated with heavier oils. For dry skin, this sealing step improves overnight hydration retention by up to 40%.
💡 Pro tip: Warm the oil between your palms before pressing into skin — the warmth improves absorption significantly and ensures an even layer rather than concentrated droplets.
Mixed into moisturiser — boosts richness without greasiness
Add 2–3 drops of squalane to your regular moisturiser in your palm before applying. This instantly transforms a lightweight gel moisturiser into a richer formula without adding comedogenic ingredients. Particularly useful in winter when your regular moisturiser isn’t providing enough barrier support, or for mixing into SPF to reduce its occasional dry-down effect.
💡 Pro tip: Mix into CeraVe Moisturizing Cream on dry skin days in winter — the squalane + ceramide combination provides exceptional overnight barrier support without needing a separate face oil step.
As a retinol buffer — reduces irritation dramatically
Squalane is one of the best retinol delivery vehicles because its emollient properties buffer the retinol against the skin, slowing penetration and reducing the irritation and barrier disruption of the adjustment period. The Ordinary Retinol in Squalane products use exactly this principle. You can also add a few drops of squalane to any retinol product you already own — mixing squalane with retinol before application makes it significantly more tolerable for sensitive skin.
💡 Pro tip: Apply retinol serum first, then immediately apply 2–3 drops of pure squalane over it — this “buffers” the retinol without diluting it, reducing adjustment period irritation by approximately 40–50%.
On hair ends — frizz control and moisture sealing
Squalane’s lightweight, non-greasy profile makes it one of the better facial oil choices for hair ends too — it tames frizz and seals the hair shaft without the heavy residue that makes most oils look greasy on hair. Apply 1–2 drops to dry hair ends as a finishing treatment. The same non-comedogenic chemistry that prevents pore-clogging means it won’t build up on the hair shaft the way heavier silicone or oil serums can.
💡 Pro tip: One bottle of squalane replaces both your facial oil and your hair serum — a genuinely multi-use product that earns its bathroom shelf space.

Frequently Asked Questions
Can oily skin use squalane?
Yes — squalane’s comedogenicity rating of 0–1 means it doesn’t clog pores even on the most acne-prone skin. Additionally, applying a skin-identical oil to oily skin signals adequate oil levels, which can paradoxically reduce compensatory sebum overproduction over 4–6 weeks of consistent use. The key is using pure squalane rather than squalane blended with higher-comedogenicity oils. Start with 2 drops and see how your skin responds before increasing.
Is squalane the same as shark oil?
Historically, squalene (the unstable natural form) came from shark liver oil — deep-sea sharks have large livers rich in squalene. This is why shark populations were being depleted for cosmetic ingredients. Modern plant-derived squalane comes from olive oil (most common) or sugarcane fermentation (Biossance’s process). Look for “plant-derived” on the label — this confirms no shark sourcing. All the products in this guide are plant-derived.
What’s the difference between squalane and rosehip oil?
Both are face oils with low comedogenicity ratings, but they work differently. Squalane is a pure emollient/occlusive — it softens and seals without any active treatment. Rosehip oil contains Vitamin A (retinol precursor), Vitamin C, and linoleic acid that provide additional brightening and barrier-repairing benefits. Rosehip is slightly more comedogenic (rating 1) and has more active ingredient properties; squalane is more universally tolerated and purely functional. They can be combined — squalane as the base carrier, rosehip oil for additional active benefits.
