What is the best Biossance 100% Sugarcane Squalane dupe?

Good Molecules Squalane Oil ($8) is the closest match on chemistry — literally the same molecule, INCI-verified single-ingredient squalane. It comes in a smaller 30 mL bottle, though: Biossance's own standard size is now 100 mL, so this isn't a same-size comparison. Per mL, Good Molecules works out to about 76% cheaper than Biossance — a real gap, but far smaller than the roughly 4x difference it used to be when both came in 30 mL bottles.

Is all squalane oil the same?

Once refined to 100% squalane, yes — it is a single, saturated, skin-identical lipid regardless of brand. Biossance sources its squalane from sugarcane rather than other plant or shark-liver sources, which is a genuine sustainability story in how the raw material is produced, but the finished molecule in the bottle does not differ.

Why does Biossance squalane cost more than The Ordinary or Good Molecules?

Less than it used to, on a per-mL basis. Biossance's standard size jumped from 30 mL to 100 mL at the same $34 price, which lowered its cost per mL to $1.13. Good Molecules ($8 for 30 mL, $0.27/mL) is still cheaper per mL. The Ordinary ($10.40 for 30 mL, $0.35/mL) is now essentially tied with Biossance — technically a touch more per mL. None of that reflects a chemistry difference; it's entirely the bottle-size math. If Biossance still costs more in practice, it's because you're buying a 100 mL commitment instead of a 30 mL trial size.

Read the actives column first — it is the apples-to-apples comparison. $ per gram of active is what the working ingredients cost you; the base-formula score is supporting evidence, not the verdict.

03 / The original

Why the original is the original

Squalane is a single, saturated, skin-identical lipid — the hydrogenated, shelf-stable form of squalene, a molecule your own skin already produces. A 100% squalane oil has no other active to disclose: it is either squalane, or it is not. Biossance's version is sourced from sugarcane rather than the shark-liver oil squalane historically came from, which is a genuine sustainability upgrade in sourcing, not a different molecule once it is in the bottle.

That sourcing story is exactly what the $34 price buys. Once refined, squalane is squalane — INCIDecoder verifies the same single-ingredient formula in Good Molecules' $8 bottle and The Ordinary's $10.40 bottle. The catch: Biossance's standard size is now 100 mL, not the 30 mL bottle Good Molecules and The Ordinary still sell, so this is no longer a same-size comparison. There is no concentration to compare, no delivery system to differentiate, and no clinical claim unique to any one brand's squalane.

So the honest verdict has changed along with the bottle: at $0.34 per mL, Biossance is now only about 22% pricier per mL than Good Molecules ($0.27/mL) — down from roughly a 4x gap when both came in 30 mL bottles — and is essentially tied with The Ordinary ($0.35/mL), which now works out very slightly more expensive per mL than Biossance's bigger bottle. The molecule is still identical, so there is still no chemistry reason to pay more. But the old "pay a quarter of the price" framing no longer holds once you account for the size change — Biossance is now price-competitive per mL, as long as you're fine committing to 100 mL rather than a 30 mL trial size.

Good Molecules Squalane Oil

Squalane

shared with original not shared rare marker — weighs more in the score

What matches: The identical single-ingredient 100% squalane, INCI-verified — the same molecule Biossance sells, just in a smaller 30 mL bottle (Biossance's own standard size is now 100 mL). There is no concentration or delivery-system difference to report.
What differs: No sugarcane-sourcing story and simpler packaging. The chemistry inside the bottle does not differ from Biossance's at all.
Who it's for: The winner — the pick if the molecule is what you're buying. $8 for 30 mL versus $34 for Biossance's 100 mL: on price per mL that is about 76% cheaper than Biossance — a real gap, but far smaller than the roughly 4x difference it used to be before Biossance's bottle size increased.

Squalane

shared with original not shared rare marker — weighs more in the score

What matches: Also the identical single-ingredient 100% squalane, in its own 30 mL bottle — the product that made squalane oil a household staple. It's a smaller bottle than Biossance's now-standard 100 mL size, not a same-size match.
What differs: No sourcing story of its own beyond "plant-derived." On a per-mL basis, no longer priced between Good Molecules and Biossance — see below.
Who it's for: The pick for a small trial size — $10.40 for 30 mL is still a much smaller commitment than Biossance's 100 mL bottle. Per mL, though, it is no longer the budget option: at $0.35/mL it now costs a shade more per mL than Biossance's own $1.13/mL.

05 / Methodology

How we verified this

Verified 2026-06-15

Every formula on this page was tokenized — split into its individual INCI ingredients — and matched against the EU CosIng ingredient database, so "Aqua," "Water," and "Eau" all resolve to the same ingredient.

The base-formula match score works like this: sharing a rare ingredient counts far more than sharing a common one. Almost every serum contains water and glycerin — that proves nothing. Almost nothing contains Ethoxydiglycol or Laureth-23, so when a candidate shares those with the original, it says something real about how the formula was built. (For the statisticians: it is an IDF-weighted Jaccard similarity over the normalized ingredient lists.)

Scores are computed, not opinions. The verdict tags are our editorial read of the actives, the scores, and the prices — and the methodology stays public so you can disagree with us precisely.
