If you're not already familiar with skin-care super ingredient squalane, here's a catch-up on the basics: Derived naturally from sugar cane, this moisturizing active hydrates your skin, promotes elasticity, diminishes fine lines, and serves as the main ingredient in Reese Witherspoon's go-to skin-care treatments. (

In an interview with PEOPLE, Witherspoon shared her passion for skin care and all the reasons that led her to team up with Biossance, a brand renowned for its squalane-based products. "I noticed Biossance at Sephora over the holidays and started using the products. I was blown away by not only how effective they were, but also the sustainability and science built into the brand's skincare line," said the star.

Designed to mimic squalene (found naturally in the human body), Biossance's squalane locks in moisture for softer, more youthful looking skin. While Witherspoon named the Squalane + Vitamin C Rose Oil as her favorite Biossance item of the moment, she also mentioned that the brand's Squalane + 10% Vitamin C Spot Serum has helped her skin combat signs of aging.

"The vitamin C products have been really helpful brightening those darker spots and the pigmentation. I just try to be really good about taking care of my skin twice a day… we all know those signs of aging, but it's really about, 'How do I feel?' Not about how it's perceived but, "How am I taking care of myself?' And I think when you talk about using products that are good for your skin, your largest organ, you are making that investment in yourself."

With a combination of squalane and vitamin C, the Squalane + 10% Vitamin C Spot Serum acts as a brightening agent to fade sun damage, hyperpigmentation, acne scars, and fine lines while delivering a healthy-looking glow. In a clinical study conducted by the brand, nearly all testers found that the serum reduced the appearance of dark spots. (

"I've never had calm, even, smooth, glowing skin in my entire life until now," commented one user, who noted struggling with uneven skin texture. "Generally one product might fix one of these issues but exacerbate the others. However, this resolves all of my issues."

"I've tried many different vitamin C serums and products, but this is the first product that is making a difference on my dark spots and they are finally lightening and going away! I love all the Biossance products I have used and am passing it on to my friends and family," wrote another shopper.

If you (or someone on your holiday gift list) struggles with dark spots, this celebrity-endorsed serum is worth a try. For a limited time, you can shop Biossance's entire site for 30 percent off with the code EXTRA30 at checkout.
