This Vitamin C Serum is Dermstore's No. 1 Best-Selling Product (Here's Why It's So Good)

We've written about vitamin C at length. TL;DR: It's one of two skincare ingredients that nearly every dermatologist we've ever met has recommended for fending off signs of aging. (The other is retinol, in case you were wondering.) Used diligently, vitamin C can soften fine lines, firm skin, brighten your complexion and provide environmental protection against future damage. It's basically the closest thing you can get to an actual fountain of youth.

And when it comes to vitamin C serums, there is one that is unparalleled in popularity and praise, and that's Skinceuticals C E Ferulic. Launched in 2005 after 40 years of rigorous testing and academic research, this potent powerhouse was one of the first—and remains one of the best—out there. 

What makes it so great? Well, for starters, see above re: 40 years of research. In a world where new launches are coming out daily, that amount of testing is hard to come by. Unlike others on the market, C E Ferulic has a lot of data that supports its safety and efficacy. Plus, the formula itself features a high concentration of stabilized L-ascorbic acid (vitamin C's sexy scientific alias), as well as 1 percent vitamin E, and 0.5 percent ferulic acid. Together, this blend works to neutralize free radicals and encourage cell turnover. To put it to you another way, it's like when Beyoncé sings with Destiny's Child. She's a queen on her own—no doubt—but there is something undeniably special that happens when Kelly and Michelle add their harmonies, right? 

Uh, $166 is a lot of money. How can I use C E Ferulic efficiently? We're right there with you. It is a hefty chunk of change. The best consolation we can offer is that a few drops (three to four to be precise) are enough to cover your entire face, which gives each bottle some mileage. Pat it over clean skin, top off with sunscreen and marvel in your slow and sustained glow.
