Vitamin C is a staple ingredient in my skincare routine, so whenever I can get my hands on a high-end version for a fraction of the price, I pounce. Which is exactly why I'm running to shop the cult-favorite Obagi Vitamin C 20% serum ($150; $105) while it's available for a rare markdown. That's right, you can grab the coveted formula, along with the rest of Obagi's professional-grade serums, for 30 percent off at DermStreet when you use the code TREAT30 at checkout as part of the brand's fall sale. You're welcome.

The serum is made for all skin types and claims to offer antioxidant, anti-inflammatory and anti-aging benefits that leave complexions bright and glowy. Indeed, Vitamin C in its active state (aka L-ascorbic acid) has shown promise for hyperpigmentation. Certain types can also boost the production of collagen in your skin, as Dr. Whitney Bowe told PureWow in March 2022.
Shoppers say this particular version, which boasts 20 percent L-ascorbic acid, is efficient in its absorbency and produces fast results. "I absolutely adore this serum; it has quickly become my favorite. My esthetician recommended it to me, and I am so glad she did. It absorbs into my skin effortlessly, leaving no greasy residue behind. After using it a few times, I have noticed a remarkable improvement in the health, brightness and smoothness of my skin. I will definitely be repurchasing this serum and I highly recommend it to anyone dealing with pigmentation issues like myself," raves one reviewer.
