Kristen Stewart put it best when she said that the key to beautiful skin is moisture, but even layering your favorite products in cold weather sometimes isn’t enough. That’s why you always need a powerhouse ingredient to deliver hydration and protect your skin—especially if you live in a climate that freezes. Our suggestion? Squalane! What is it, what's the difference between squalene and squalane, and what are the best products to try? Keep reading to find out.
What is it?
Squalene is a colorless poly-unsaturated hydrocarbon liquid that’s found naturally in many animals and plants, including human sebum. Yes, the word ‘sebum’ sounds gross, but it’s incredibly important to your skin. Essentially, it’s one of the many natural lipids your body produces to lubricate and protect your skin. (It’s estimated to make up about 10 to 12 percent of your skin’s oil.) Unfortunately, because of its efficacy, it's often harvested in unethical ways—however, as long as you're responsible about where you get it, it's all good. It can be, and is commonly, harvested from plant sources like olives, wheat germ oil, and rice bran. The ingredient comes in two forms: squalene and squalane, a more common, lighter, hydrogenated version. They're both equally effective, but squalane has a longer shelf life because it's more stable.
What does it do?
Squalene and squalane are used in skincare products as a highly-effective emollient and natural antioxidant. Historically, they’ve been used in the medical field to treat wounds and skin problems. Over time, using squalane in skincare can reduce wrinkles, eliminate scars, reverse UV damage, lighten freckles and erase skin pigmentation, all while fighting free radicals. On some people it can even be used as a spot treatment.
Who should use it?
Squalene and squalane both make great skin moisturizers. They’re natural emollients, so they lock moisture into your skin, help prevent fine lines, and ease dry patches. Anyone can use either version, but squalene is heavier, making it helpful for extra-dry or mature skin, while squalane is great for acne-prone or oily skin.
Looking for a body lotion that is non-tacky but still does what it promises? Kiehl’s Creme de Corps ($30) has been a top seller since the 1980's, and it's full of hydrating, moisture-locking ingredients like squalene, beta-carotene, and sesame oil.
Celebrity facialist Joanna Vargas calls this her "red-carpet cornerstone for glowing skin," and after trying it, we get why. It combines all the things you want in a serum—Vitamin C, moisturizing squalane, fatty acids and antioxidants—and none of the stuff you don't, as every product is vegan and cruelty free.
The issue with most tinted moisturizers is that they're, well, not moisturizing enough—particularly if they have SPF. But there's a reason bareMinerals' Complexion Rescue Tinted Hydrating Gel Cream ($32) is a favorite of off-duty celebs. Thanks to squalene, it provides the perfect mixture of hydration, SPF, and coverage to give your face a natural-looking, even glow.
Tatcha is one of those brands where you can pick anything up and use it without doing any research, and the product will blow you away. They use squalane, but the real hero of the product is red algae extract—it both restores and hydrates the skin around your eyes, which can feel life-saving after a long night.
Okay, the packaging for Patrick Ta's Major Glow Body Oil ($52) may be a bit hard to get the hang of. But the product inside—a nourishing, brightening formula with Vitamin E as well as squalane—is so great that it's worth just finding a way around it. It's not tacky, and the shimmer is not for the faint of heart. Use an applicator like Patrick Ta's Body Brush ($35) for maximum glow.
Because squalane is such a hydrating ingredient, it makes sense that it would be included in this super-hydrating overnight mask from Youth to the People. Hyaluronic acid and glycerin help round out the hydrating effects, and a stable form of Vitamin C lets you wake up with glowing, happy-looking skin.
Tata Harper's all-natural ethos extends to their squalane, which is plant-derived. Combined with Alfalfa and Vitamin A, this cleanser keeps your face hydrated and nourished while eliminating free radicals and damaging chemicals. It's perfect for anyone who double-cleanses or gets dry skin from their face masks.
Biossance loves squalane so much that they've based their entire brand around it, making them one of the few fully EWG-certified beauty brands out there. But with their Glycolic Renewal Facial ($68), they've created something not only moisturizing but renewing. Fans of Drunk Elephant's Babyfacial ($80), meet your new favorite mask.
Squalane is an admitted favorite ingredient of skincare master Indie Lee (she once said she doesn't go a day without it,) so naturally, we had to include a product from her eponymous line. The brand's Daily Vitamin Infusion ($65,) uses squalane as its main ingredient but blends it with rosehip seed and avocado oils, and Vitamins A, E, and C, for a true one-and-done facial oil.
