As someone who struggles with acne, I've never really been comfortable with people staring at my face for a prolonged period of time. So you can only imagine how bizarre it felt when my family and friends began gawking at my complexion after I started using the Biossance Squalane + Vitamin C Rose Oil (Buy It, $74, sephora.com), a celeb-loved formula that's helped Reese Witherspoon and Jonathan Van Ness, who have both partnered with the brand, get their red carpet glow.

As its name suggests, the facial oil's all-star ingredients are squalane and vitamin C, which come together to hydrate and brighten the skin, respectively. Rose oil adds an extra boost of radiance, lending its antioxidant-rich, soothing properties to assist in balancing and moisturizing skin.

The Squalane + Vitamin C Rose Oil has been a game changer for my skin's dullness and dark spots, which are mostly the stubborn remnants of maskne breakouts. But what I wasn't expecting was to see was an almost-instant improvement in my skin's overall suppleness and dewiness. That's thanks to Chios crystal oil, a collagen-boosting ingredient that helps firm and increase the skin's elasticity. (

Since the oil is so hydrating, my skin has a bounce to it that it most certainly didn't have before; it stopped my mom in her tracks and made her want to try the face oil for herself. On top of that, it leaves my skin positively radiant — so much so that friends complimented my skin after a six-hour flight that boarded at 7:00 a.m.

Honestly, I'd say that I saw results within three to five days of incorporating the Squalane + Vitamin C Rose Oil into my nightly routine. Sure, the pimples still pop up — there's only so much you can do in this time of constant KN95 mask-wearing — but a smooth, dewy glow now overpowers any spots that may come my way. After trying the face oil, it's not hard to see why it's a favorite of Witherspoon's, or why it has a near-perfect 4.7-star rating from Biossance shoppers, many of whom had a similar reaction to using the product as I did.

"I will never use another oil/moisturizer in my life," one reviewer wrote. "Never [has] my skin felt so plump and glowy. I get compliments every week on my skin and have turned on a few people to the magic that is this oil."

Whether you're battling dark spots, uneven texture, dryness, or fine lines, the Biossance Squalane + Vitamin C Rose Oil tackles it all. Grab a bottle today.
