Want Reese Witherspoon's gorgeous glow? Her favorite vitamin C oil is nearly 40% off at Amazon

Reese Witherspoon has been dazzling Hollywood for over two decades. She also has her own book club, as well as lifestyle and clothing brands. With Apple TV+'s The Morning Show heading into its fourth season, it doesn't look like she'll be slowing down anytime soon. So how does she do it all and still look that good? She's got a few tricks up her sleeve, and one of them is on sale at Amazon: Biossance Squalane + Vitamin C Rose Firming Oil, now $47 — a nice discount from its original price of $74.

This serum uses vitamin C to brighten skin, squalane to lock in moisture and chios crystal oil to improve firmness.

Why is it a good deal?

At almost 40% off, Biossance Squalane + Vitamin C Rose Firming Oil is at one of the lower prices we've seen over the last several months, making it a great time to snap up this serum for yourself. Also, with an extra $27 in your pocket, you can invest in even more quality skin care.

Why do I need this?

A quality vitamin C oil can transform your skin-care routine, especially if you're looking to brighten and firm the face and neck. There are plenty of options on the market, but Biossance's top-selling oil stands out for its clean, cruelty-free ingredients and impressive celebrity backing. Witherspoon, who uses the oil nightly after she cleanses, mists and moisturizes, is also Biossance's global brand ambassador. The actress shared her step-by-step before-bed beauty practice on Instagram.

This oil-soluble vitamin C is formulated to help revive and brighten dull skin. Sugarcane-derived squalane, a natural moisturizer, aims to restore and lock in hydration. Biossance also uses chios crystal oil to improve skin's elasticity and firmness while reducing the look of fine lines and wrinkles. Rose oil, the final ingredient, offers a light floral scent and a little extra radiance. (Don't we all want Reese's glow?)

What reviewers say

Reese isn't the only fan — plenty of reviewers say this product is top-notch.

"Love the way it feels. I carry one with me in addition to having one at home. I love it so much that I now get these as gifts for colleagues and friends," one shopper said. "Must-have item."

This five-star reviewer said that "every woman over 50 should have this product on hand. Pat it onto your face and you can almost hear your skin sigh in relief. It's fabulous under moisturizer or alone — any that's left over is lovely on your hands too."

Another fan admitted, "I use this occasionally and probably should use it daily to actually reap the stated benefits. It does moisturize nice without looking too greasy and a little goes a long way, just a few drops does the entire face and neck."

One customer raved about how the product "makes my skin glow" and added, "I'm amazed at how soft and smooth my skin feels from this oil. Just a couple of drops work for my whole face. I'm in my mid 60s and my skin looks great."

"I feel it’s expensive but worth it," said a final user. "My skin is more clear and it moisturizes my face without making it feel and look too oily. Best face oil I’ve used! Will keep buying."

This serum is simple to use: Just press a few drops into your face, neck and chest after you apply your go-to moisturizer.
