We’re here to share what we know — but don’t take it as medical advice. Talk to your medical provider if you have questions.

You might say that squalane is the true neutral of moisturizing ingredients. No matter your skin type, it helps with maximizing the absorptions of moisturizing agents into your skin, keeping your face fresh, hydrated, and glowing.

Squalane is also lightweight and non-pore clogging, making it great for acne-prone skin. Historically, squalane oil was harvested from the livers of sharks,¹ but this was obviously harmful to marine ecosystems (not cool). In skincare today, squalane is most often synthetic or plant-based, derived from sources like olive oil, sugarcane, and rice.

Squalane vs. squalene

When it comes to your skin, squalane is better than squalene. We know, we know — what difference could one letter make? Basically, squalene is found in nature, and squalane is its refined form.²

Which one is right for your skin routine? We’ll repeat: you definitely want squalane, not squalene. Pure squalene needs to be refined in order to be stable;³ that’s why you’ll find its shelf-stable form, squalane, in certain skincare products.

How to use squalane in your skincare routine

Because of squalane’s balancing properties, it’s a popular ingredient in cleansers and moisturizers. You can also buy pure squalane oil, which can be used two ways: a) add a couple drops to your moisturizer, or, b) add a couple drops directly to your skin, like a serum.

When you opt for a product with squalane, it can help your skin feel soft without feeling greasy — so long as it has the right mix of ingredients. We’ll vouch for the following products with squalane as not having any potentially pore-clogging or irritating ingredients.

We did our research so you don’t have to.
