Quick Comparison
| Squalane | Squalane | |
|---|---|---|
| Typical Concentration | Can be used pure (100% squalane oil) or in formulations. Apply 2-3 drops after water-based products. Can be mixed with moisturizer. Safe for morning and night use. Non-comedogenic rating: 0-1 (very unlikely to clog pores). | Can be used pure (100% squalane oil) or in formulations. Apply 2-3 drops after water-based products. Can be mixed with moisturizer.

Mechanism of Action
Squalane
Squalane is the fully hydrogenated form of squalene—a C30 isoprenoid hydrocarbon. As a saturated branched-chain hydrocarbon, squalane forms a non-occlusive emollient film that fills intercellular lipid spaces and reduces transepidermal water loss (TEWL) by approximately 20-30%. Squalene comprises ~12% of human sebum (synthesized via mevalonate pathway); squalane's structural similarity confers high biocompatibility and minimal comedogenic potential. Hydrogenation of squalene's six double bonds eliminates oxidative susceptibility—squalene peroxidizes with UV exposure while squalane remains stable. Squalane penetrates the stratum corneum and may support barrier lipid organization. Plant-derived squalane (sugarcane, olive) is structurally identical.

Risks & Safety
Squalane
Common
Essentially none. May cause breakouts in a small percentage of people despite low comedogenic rating.
Serious
None.
Rare
Allergic reaction is extremely rare.

Full Profiles
Squalane →
A lightweight, non-comedogenic emollient oil derived from squalene — a lipid naturally produced by human sebaceous glands. Squalane (the hydrogenated, stable form) mimics the skin's natural oils, making it an excellent moisturizer that rarely causes breakouts. It softens skin, reduces water loss, and has antioxidant properties. Increasingly sourced from sugarcane and olives rather than shark liver.
