Squalane
Squalane is a stable, non-comedogenic oil that mimics the skin's own natural lipids, sealing in whatever hydration went on underneath it. It's meant to go last — after every water-based serum, right before or instead of a moisturizer.
How it works
A saturated, completely stable branched-chain hydrocarbon that mimics endogenous follicular squalene to act as a bio-compatible emollient. It seals micro-fissures between desquamating keratinocytes, restoring surface elasticity and softening structural texture without comedogenic occlusion.
In practice, applying it before a water-based serum instead of after would trap that serum out — the order matters as much as the ingredient itself.
How to introduce it
No wait needed — apply the next step right away. Judging Squalane before week 4 means judging it before it's had time to actually work — most of what reads as "this isn't doing anything" in the first couple of weeks is just too early to tell.
- Always the last step before sunscreen (AM) or the final step (PM).
Who should be careful
Squalane's safety rating is the lowest tier tracked here — well tolerated by most skin types, including sensitive skin, without a slow introduction.
Common in these product forms
Among the products Skinzy tracks in India that contain Squalane, it most often shows up as a serum or a oil.
Questions people ask
A skin-mimicking oil that seals in hydration — always the last step, after every water-based serum.
Most people see a fair result around 4 weeks of consistent use — judging earlier usually means judging too soon.
Either — Squalane works in both a morning and an evening routine.
