Vitamin C, also called ascorbic acid, is having a moment on TikTok, but don’t think it's all hype — vitamin C serum is a true powerhouse skincare ingredient that offers both short and long-term benefits. So if you're not already harnessing the holy-grail powers of a vitamin C serum in your skincare routine, you're missing out on some key benefits. Just like azelaic acid and niacinamide, vitamin C is an expert-approved favorite ingredient that should be in everyone's skincare routine, regardless of your skin type or sensitivity.

The Best Vitamin C Serums

The only caveat: not all vitamin C serums are created equal. Vitamin C is unstable, meaning it can quickly expire due to light and air exposure. Plus, many serums contain different amounts of vitamin C, so make sure you check the label to see if it's the right percentage for your skin concerns.

Our beauty editor, Nicole Saunders, chatted with board-certified dermatologists to discuss everything you should know about shopping for a vitamin C serum.

What is a Vitamin C Serum?

A vitamin C serum is a lightweight liquid or gel-textured skincare product that is infused with various concentrations of vitamin C. Most stable vitamin C serums, such as SkinCeuticals C E Ferulic and Vichy LiftActiv Vitamin C Serum, are sold in a container that shields them from light or an amber glass bottle, explains board-certified dermatologist Dr. Supriya Tomar, M.D.

Don’t worry: Vitamin C serums sold in other containers, including InstaNatural Vitamin C Serum With Hyaluronic Acid, are safe to use, but they might not last as long as other variations. One way to help stabilize and boost the efficacy of any vitamin C serum is to store it in a skincare fridge.

What Does Vitamin C Serum Do For the Skin?

For board-certified dermatologist Dr. Joshua Zeichner, M.D., vitamin C is undoubtedly the ultimate multitasker in skincare. “It is a potent antioxidant and neutralizes free radical damage to protect the skin,” he says. Vitamin C also lightens dark spots, promotes collagen production, and strengthens the skin.

But that’s not all: Vitamin C acts as a powerful antioxidant, especially when paired with an SPF 30 or higher, according to Tomar. “Most sunscreens only provide up to 99% protection from UV rays, and vitamin C serums can actually act as a booster to that, helping to fill in the missing protection. So not only does it help correct existing damage, but it will help prevent additional damage as well,” she explains.

How We Chose

We know how important your pores are, which is why we only featured the most trusted vitamin C serums on the market. Our beauty editor considered the potency, packaging, texture, and feel of these products, and we combed through hundreds of reviews on Amazon, Ulta, Sephora, and more. Plus, since vitamin C isn't the only ingredient you want in your overall routine, many of these formulas contain a plethora of other skin-saving ingredients, like hyaluronic acid, vitamin E, and more.

C E Ferulic

SkinCeuticals C E Ferulic serum has earned a cult following from beauty obsessives and skincare experts alike, so it’s no surprise this vitamin C serum earned our best overall distinction. This serum delivers advanced environmental protection, and it improves the appearance of wrinkles and loss of firmness.

The award-winning serum also works to improve the overall brightness of your skin's complexion. It's incredibly effective, and it's worth the splurge, according to board-certified dermatologist Dr. Alain Michon, M.D., of Ottawa Skin Clinic.

“This serum features a synergistic antioxidant combination of 15% pure vitamin C (ascorbic acid), 1% vitamin E (alpha-tocopherol), and 0.5% ferulic acid. This combination enhances the protection against environmental stress and damage caused by free radicals,” explains Michon.

Plus, it comes in an amber glass bottle to help stabilize its potency.

FAQ

Q: What concentration of vitamin C is good for your skin?

A: “The different amounts generally indicate how impactful your results will be, and most come in at 10% because it’s well tolerated by almost any skin type,” says Tomar. “20% will yield stronger results, but sensitive skin types should tread cautiously. Anything above that can lead to irritation. And the rule of thumb is to always keep the concentration above 8%, even for beginners.”

Q: In what order should you put on vitamin C serum?

A: Tomar says that vitamin C serum is considered an active product, so it should go on a freshly washed and toned face and before your moisturizer and sunscreen.

Vitamin C is considered an active product, so it is most effective after the face is cleansed and toned. After you slather on the serum, you should follow up with a moisturizer to seal it in, advises Tomar and Michon.

“Since sunscreen is the most important step of the skincare routine, it is incredibly important to apply sunscreen after applying the vitamin C serum and moisturizer in order to protect the skin against free radicals effectively,” adds Michon.
