Squalane Benefits
Squalene Difference, Layering Order and Picks by Skin Type

Squalane benefits: what it does and why

Squalane is a light moisturizing oil. Rather than drawing in water, it fills a thin layer on the skin surface so water escapes more slowly.

• Keeping water in: oils sit between the cells of the outer skin layer, and squalane fills those gaps so less water evaporates.
• Smoother texture: it spreads thin and smooths the surface, so rough skin feels softer.

Squalane suits skin because our own sebum contains a similar substance, squalene (Picardo et al., 2009). Skin does not treat it as foreign, so it sinks in without much stickiness.

Of the 2,426 full ingredient lists we have collected, 439 contain squalane. That is a little over 1 in 5, so you meet it often in creams and serums.

Squalene difference and sourcing

The names are easy to mix up. Squalene spoils quickly in air, and adding hydrogen to it makes squalane, which does not. That is why cosmetics use squalane.

It once came from shark liver, but today it mostly comes from olives or sugarcane. The finished ingredient is the same whatever the source, so it works the same on skin.

Which skin suits squalane

• Dry skin: layered over a moisturizing cream, it keeps tightness away into the afternoon.
• Oily and combination skin: a light finish instead of a heavy cream, since it feels less greasy than most oils.
• Sensitive skin: it is gentle, so a simple fragrance-free squalane product works well.
• Skin on retinol: it eases the dryness retinol leaves behind.

How to choose squalane

• Texture: pure oil goes on last as a few drops, while a cream is a moisturizing finish on its own. If you are new to it, start with a squalane cream.
• What comes with it: products that also carry water binders such as hyaluronic acid or panthenol keep skin moist longer.
• Fragrance: for sensitive skin, check that the list has no fragrance.

Squalane products by skin type

From our collection, we picked products with a generous amount of squalane and a clear partner ingredient. Of our 439 squalane products, about 7 in 10 also contain vitamin E (tocopherol), which keeps the oil from spoiling.

• esNature Aqua Squalane Moisturizing Cream leads with squalane, as the name says, and adds hyaluronic acid and panthenol. It suits skin that is both dry and sensitive.
• Anua PDRN Hyaluronic Acid 100 Moisturizing Cream adds hyaluronic acid and centella to squalane, an easy pick for combination skin.
• La Roche-Posay Toleriane Dermallergo Cream is a simple cream with a short list, worth a look for sensitive skin that dislikes long formulas.
• The Ordinary Retinol 0.2% in Squalane dissolves retinol in squalane, a gentler way to start retinol with less dryness.

Squalane layering order and what to watch

• Order: apply from light to heavy, so squalane goes last as a few drops after serum or cream. It seals in the water from earlier steps.
• Amount: two or three drops of pure oil are enough. More looks shiny.
• First use: if oils tend to bother you, try a small area first.

Is plant squalane different from shark squalane?

Only the source differs. The finished ingredient is the same, and most cosmetics now use squalane from olives or sugarcane.
