Shoppers Call This Anti-Aging Oil 'Gold in a Bottle,' and It's Under $20 for 72 Hours Only

If you have dry skin, it may seem at times like no skincare product in the world can provide enough moisture. But according to shoppers, squalane oil might be what your routine is missing—specifically this high-quality version that's on sale and less than $20 before Black Friday.

Biossance's hydrating oil's ingredient list is right in its name: 100 percent squalane, an emollient that locks in hydration. The body's natural production of squalene decreases with age, which can lead to dryness. That's where the sugarcane-derived oil comes in, keeping the skin's microbiome healthy and helping the products you layer on top of it penetrate even further for better results.

To buy: $19 (was $32); biossance.com.

It also works to improve elasticity and plump up skin (read: fill in fine lines) for a more youthful appearance.

The Biossance Squalane Oil is a skincare multitasker that shoppers can't get enough of. "This stuff is gold in a bottle!" one said, before adding, "I have sensitive skin that is oily. Squalane hydrates without clogging my pores, and my sensitive skin loves this stuff. Biossance as a whole has turned into my holy grail skincare regimen."

Another shopper reported, "I have dry skin, and as I'm now in my late 30s, I'm noticing lots more fine lines, and my skin is just dull. I've tried lots of products… After two weeks of using this line, I've noticed significant differences. Reduction of fine lines, plumping and brightening of skin, and the dullness is gone."

"I use this for my face, hair, and body," a final customer wrote, adding, "I like it because the oil is not very heavy, and it keeps my skin and hair very soft."

Don't miss out on hydrated and dewy skin. Head to Biossance to snag the squalane oil while it's on sale for 40 percent off and only $19 through November 20.
