Hey, gorgeous! Welcome back to Worth It , a breakdown of the absolute best new beauty products we\u2019ve tried. We \u2019 re talking that post-it-up-everywhere-and-sing-its-praises-from-the-rooftops kind of love. Keep reading to find out why you can\u2019t miss out on the Biossance Squalane and Vitamin C Dark Spot Serum, and catch up on all the latest Worth It breakdowns here . The Promise While the whole \u201cmilk does a body good\u201d sentiment may hold some truth, I prefer to kick my day off with generous amounts of vitamin C\u2014from my morning smoothie to the antioxidant-loaded skincare I layer on. The vitamin, a robust antioxidant, has been considered a powerhouse for treating sun damage and hyperpigmentation , and Biossance combined it with eco-conscious, sugarcane-derived squalane (an anti-inflammatory) and white shiitake mushroom to create their Squalane and Vitamin C Dark Spot Serum . The brand claims this formula can help quickly degrade existing dark spots while preventing new ones from forming\u2014minus any negative reactions. According to dermatologist Dhaval G. Bhanusali, MD, irritation is a common issue when products employ a high percentage of vitamin C, but the addition of squalane in this serum directly counteracts that. He adds that squalane can help retain hydration and it's usually well-tolerated by all skin types. This is because it is a natural emollient with very similar content to our skin\u2019s own natural oils, cosmetic chemist Ginger King explains. Factor in the white shiitake mushroom and you\u2019ve got one lean, mean, dark spot-fighting machine. \u201cWhite shiitake mushroom is a natural form of kojic acid, which can help brighten skin, exfoliate, and prevent further darkening,\u201d King adds. Why I\u2019m Obsessed I\u2019m always trying to stay ahead of the changes to my complexion that come with getting older. I\u2019m both Filipino and Ukranian, and have a medium skin tone. While signs of aging haven\u2019t manifested in the form of wrinkles quite yet, battling post-breakout spots has become more of a struggle. I didn\u2019t realize my marks were actually post-inflammatory hyperpigmentation until Dr. Bhanusali told me. \u2018They\u2019re super common for people with richer skin tones,\u201d he says. I was already using a retinol-infused serum to break up the more-concentrated-pigment spots and boost collagen production, but the spots would still linger for weeks. Once I started incorporating the Biossance Squalane and Vitamin C Dark Spot formula into my routine, it seemed almost as if I hit the fast-forward button on the overall fading process. I applied two pumps twice a day, and within a few days, I noticed that my complexion felt softer and more hydrated. After two weeks, the post-breakout marks I used to fixate on during video calls had faded completely. Even my soul-crushing, hormonal pimple that came and went during this period of time didn\u2019t have a chance to leave its mark. While Dr. Bhanusali notes that the more tangible results would come after the four-week mark, the halfway point is already looking pretty promising. On top of my visibly fading hyperpigmentation, my skin looked plump, smooth, and glowy (even in bad lighting). Between its spot-fading powers and soothing hydration, this formula was the one-two punch my skin needed; and I'm constantly singing its praises to everyone I know.
