What is Squalane?
Natural beauty CEO Indie Lee recently said she can’t go a day without using her favorite skincare ingredient: Squalane. Naturally occurring in our own bodies, it is among the most common lipids produced by human skin cells, making up approximately 10 percent of our sebum. On the skin’s surface, it acts as a barrier, both protecting the skin from moisture loss and providing a shield for the body from environmental toxins.
Internally, the liver produces squalane as a precursor to cholesterol.
It’s also an antioxidant-rich, age-fighting emollient that’s commonly used as an additive in deodorants, lip balm, lipstick, moisturizers, suntan lotions, supplements and a variety of other cosmetic products. Because it mimics our body’s own natural moisturizers, it can rapidly penetrate the skin and is absorbed quickly and completely without any lingering residue.
Purpose of Squalane
The body’s squalane levels start declining when we’re in our 20s. Applying nourishing squalane will lubricate your skin’s surface and can help you achieve a softer texture and smoother appearance sans greasiness. The lightweight, odorless liquid has antibacterial properties and can be effective in treating the symptoms of eczema. Acne sufferers can reduce excess oil production by using it as a spot treatment to balance the complexion. Over time, using squalane can reduce wrinkles, eliminate scars, reverse UV damage, lighten freckles and erase skin pigmentation while fighting free radicals.
On the hair, it works as a conditioner that makes your strands shiny, supple and strong. When ingested, squalane capsules are marketed to protect the body from an assortment of ailments including Arthritis, cancer, hemorrhoids, rheumatism, psoriasis, and shingles.
Squalane vs. Squalene
Squalane is a hydrogenated version of squalene that makes it more stable against oxidation when exposed to air.
Because squalane is cheaper, breaks down more slowly and has a longer shelf life than squalene, it is most commonly used as an ingredient in beauty products, typically with an expiration date of two years after opening.
Shark liver oil is another name for squalane and squalene. The liver organs of deep-sea sharks like chimeras, gulper sharks, kitefin sharks and Portuguese dogfish are prime sources for highly-concentrated squalene.
The sharks’ slow growth and infrequent reproduction cycles partnered with overfishing are causing scarcity in many species. A non-profit organization dedicated to marine conservation called BLOOM released a 2012 study entitled “The hideous price of beauty: Cosmetics industry drives deep sea shark extinctions” warning the sharks that produce squalene have neared extinction in just a few years’ time to feed the consumer need.
The Food and Agricultural Organization (FAO) reports that over a quarter of shark species are over-exploited for commercial reasons. More than 200 species are on the red list of the International Union for the Conservation of Nature (IUCN).
The BLOOM report claims cosmetics use accounts for 90 percent of shark liver oil production worldwide, contributing to approximately 2.7 million deep sea shark deaths annually.
To expedite collection fishermen may cruelly practice “livering” – removing the organ and discarding the carcass overboard, throwing injured animals back to sea suffering and still alive.
Non-shark squalene can be created synthetically or extracted from vegetable sources like amaranth seed, olives, palm, rice bran and wheat germ. Look for the words '100% plant-derived,' 'vegetable based' or 'vegetable origins.' If the label doesn’t indicate its specific source, ask the manufacturer if a product contains squalene derived from sharks.
When in doubt, you don’t have to do without.
