Psst: I Found a Secret SkinCeuticals Sale on the Brand's Cult-Favorite Products (Yep, Including the C E Ferulic Serum)

Backed by decades of rigorous testing and academic research, this serum is continuously praised for minimizing signs of aging and evening out complexions. It's packed with 15% pure vitamin C, after all, which studies suggest can combat signs of aging and hyperpigmentation, along with vitamin E and ferulic acid, which have been shown to help reduce skin inflammation and preserve firmness so your skin stays snatched. All it takes is four to five drops of this stuff per day to start reaping the benefits, and according to buyers, it may start working its magic sooner than you think. "Noticed immediate effects in the same week," writes one reviewer. "[It gave] a nice glow to my skin... also, after a [few] weeks, my spots were noticeably more faded."

If our wellness director, Sarah Stiefvater, gave this aforementioned cream her stamp of approval, rest assured that it does what it claims to. In fact, countless buyers have said it's the reason their skin feels softer and more supple than ever. Here's why Stiefvater is obsessed: "After about a month, I noticed that some of the fine lines on my forehead that had been bothering me were less defined, and my skin overall feels both smoother and plumper." That's likely thanks to its hefty supply of proxylane, a potent ingredient that's been shown to significantly reduce the look of wrinkles and sagging, as well as improve the overall appearance of skin. The bonus is that the 1.7-ounce jar goes a loooong way, which is all the more reason to grab two jars on sale and be set through the year.

In case you haven't heard, the Skin Cancer Foundation highly recommends that you wear sunscreen *every* day year-round, including in the fall and winter. If there's one sunscreen you won't mind incorporating into your skincare routine each morning, it's this guy. It's formulated with 1% tranexamic acid, 2% niacinamide and 0.3% phenylethyl resorcinol, ingredients which all come with the potential benefits of brightening and evening skin tone, so you can expect this SPF 30 formula to do more than just protect you from the sun. "I am amazed at how much my sunspots have faded after faithfully using this product for four months," one reviewer shares. "I love that it is multi-purpose. It's both an effective sunscreen and fades skin discoloration. I won't be without it."

This bright green gel has earned hundreds of glowing reviews, with many buyers claiming that its cooling effect helps calm their skin better than their prescription skincare. Um, that's all I needed to hear, but the product is also meant to hydrate skin and deliver a "fresh-looking" complexion, thanks to hero ingredients like eucalyptus leaf and hyaluronic acid. Better yet, the brand says it works for all skin types (even those with acne-prone skin), so I wouldn't be surprised if it sells out before anything else—especially since it's marked down for as low as $68.
