Biossance 100% Squalane Oil Review: One Ingredient, Three Jobs
A full review of Biossance 100% Squalane Oil: the single ingredient formula, how the 100 ml pump earns its keep across face, body and hair, and who a pure oil actually serves.

How this review was made: from the manufacturer's published formula and specifications, the live Amazon listing, and recurring themes in owner commentary. Eclat Press does not claim hands-on testing it has not done, and publishes no scores.
One ingredient, read properly
The ingredient list is the product name: squalane, derived from sugarcane as printed on the bottle. Squalane is the stabilized form of squalene, a lipid in skin's own surface oil, which is why it spreads thin, absorbs fast for an oil and rarely provokes the complaints richer plant oils collect. There is no fragrance because there is nothing in the bottle to carry one. For reactive skin, that absence is the formula.
Face, body, hair: the pump's three jobs
On the face it is a sealing step, pressed over moisturizer to slow water loss overnight. On the body it behaves like a dry oil, softening without the residue that makes people skip body moisturizer. On hair it is an ends smoother in pea sized amounts. The 100 ml size only makes sense read this way: it is priced and pumped as a staple, not a precious serum, and owners who use it across all three jobs are the ones who repurchase on schedule.
What owners keep saying
The praise is about texture and tolerance: absorption without a greasy film, calm comfortable skin, no scent and no new irritation, including from owners whose skin rejects most oils. Complaints are about calibration. Some owners expected a richer cushion and find squalane almost too light on very dry patches. The pump delivers a body sized dose, so face users develop a partial pump habit. And households that adopt it everywhere empty the bottle faster than the size led them to expect.
There is almost nothing to review here, and that is the achievement.
From the verdict
In Owners' Hands
Recurring themes, in aggregate and without numbers we cannot stand behind.
What owners praise
- Absorption without a greasy film, the quality owners mention most across face, body and hair use
- Calm, comfortable skin with no scent and no new irritation, reported by sensitive skin owners
- The big pump bottle lasting through months of multi use
What owners question
- Some owners expected a richer, more cushioning feel and find squalane almost too light on very dry patches
- The pump can dispense more than a face application needs until the partial pump habit forms
- A minority use it so broadly across body and hair that the bottle empties faster than planned
Consider Instead

Biossance Squalane + Vitamin C Rose Oil
The same base with a vitamin C and a rose character, if you want your oil step to do visible brightening work as well

Biossance Squalane + Omega Repair Cream 3.38 fl oz
If your skin needs water and barrier lipids, not just a seal, the cream addresses dryness the oil alone cannot
Questions, Answered
Can I use 100% Squalane Oil instead of a moisturizer?
It seals, but it does not hydrate in the water sense: an oil slows moisture loss from skin that is already hydrated. Oily and combination skin sometimes runs it as the only final step happily. Dry skin should layer it over a moisturizer or a hydrating serum, which is how the Biossance system itself uses it.
Will it clog pores or feel greasy?
Owner sentiment says the opposite more than for any oil in this hub: the recurring praise is absorption without a film. Dose is the variable. Two or three drops pressed over a face is a seal; a full pump is a body application, and owners who blur that line are the ones reporting greasiness.
