International Squalane Day – The Ultimate (Shark-Free) Moisturizer 
October 13, 2022

October 14 is International Squalane Day! 

In honor of the holiday, we decided to take a deeper dive as to why this illustrious ingredient should be a regular part of your skincare routine. 

If you look in your medicine cabinet, chances are that you will find “squalane” in some of the skincare or cosmetic products that you are already using daily. See, you’re already a fan, and you didn’t even know it!  

The Difference Between Squalane and Squalene in Skin Care

Some questions you might have: what is squalane? Is it “squalane” with an “a” or “squalene” with an “e”? Squalene (with an “e”) is a lipid that is made naturally by our oil glands to hydrate and protect the skin barrier. Unfortunately, after the age of 30, our body starts producing less squalene which is why we need to supplement it by using “squalane” (either by itself or as an ingredient in our skincare products). Squalene, naturally, is not shelf-stable – so “squalane” (with an “a”) is simply the naturally hydrogenated/shelf-stable version of squalene. 

Is Squalane Good for the Skin?

Squalane oil is non-comedogenic (meaning it won’t make you break out) and beneficial for all skin types, but most especially those with dry, dehydrated, mature, or compromised skin. It’s also antioxidant-rich and prized for its ability to fight free radicals and prevent skin damage.  

Apply a few drops after a shower or emerging from the water, as it naturally seals in moisture and boosts collagen production for healthier, younger-looking skin. Smooth over hair and onto the ends to add shine and reduce breakage. We consider this ingredient the ultimate moisturizer for hair and skin! 

There Might be Shark in Your Skin Care!

Squalane is also an ethically controversial ingredient. The richest source of squalene is shark liver. Yep, shark liver. It is estimated that 3 million sharks are killed annually to provide squalene for sunscreen, foundation, tanning lotions, lipstick, moisturizers, and other cosmetic products. Yikes, you might want to go back to your medicine cabinet and check that label again! If it doesn’t say plant-derived, you need to assume it came from a shark.
