INCI: Squalane
In short: Squalane delivers barrier support and softening, suits most skin types, and the evidence behind it is strong.

how it was measured
Measured on skin-surface smoothness and softness from the applied lipid film, with a modest drop in evaporative water loss; on contact, by mechanism.
The molecule
The Glow take
One of the ingredients I trust most.
When your goal is repairing a stressed moisture barrier, Squalane delivers, and the research properly backs it up. Gentle enough that most skin types can reach for it.

- barrier support
- softening
strong evidenceGood evidence as a stable, non-irritating emollient that supports barrier lipids and reduces dryness.

The hydrocarbon family, at a glance
5 hydrocarbon entries in the base, Squalane among them. 3 of the 5 are an emollient.

Where it fits in your routine
This one works on contact — there is nothing to wait for.
What that covers, and what it does not
- Measured on: skin-surface smoothness and softness from the applied lipid film, with a modest drop in evaporative water loss.
- Squalane is a saturated branched hydrocarbon that spreads as a thin film, fills between corneocyte edges and slightly slows evaporation; that is a physical effect present as soon as it is applied.
- The base's barrier_support score of 7 rests on that film and on squalane's oxidative stability, not on any trial.
- No published study gives a time course for squalane specifically, so nothing multi-week should be claimed for it -- the 5-20% use range in the concentration clue is a formulation figure, not a tested dose.
No timing study identified. Emollient film physics; squalane's stability and skin-lipid similarity are documented in cosmetic chemistry literature rather than in clinical onset trials.
Plays well with
- ceramides
- humectants
Squalane, answered
Is Squalane safe during pregnancy?
Yes. Squalane is considered safe to use during pregnancy and breastfeeding. As with anything, if you are unsure it is worth a quick word with your doctor or midwife.
Who should avoid Squalane?
Approach Squalane with care if any of these apply to you: acne prone (in high amounts).
What concentration of Squalane actually works?
Squalane tends to do its job in the 5 to 20% range. Much lower and it is likely underdosed.
