The 11 Best Vitamin C Serums We Tested and Recommend For Glowing Skin

With so many different types of serums on the market, it can be tricky to just figure out what each one does, not to mention whether it deserves a place in your skincare routine. If you’re going to invest in just one, board-certified dermatologist Diane Madfes, MD recommends opting for a vitamin C serum.1One of the main benefits of vitamin C is that itprotects against environmental stressors, like UV light and pollution, which can cause free radical damage to the skin. It’s a powerful antioxidant thatpromotes a smooth, clear, and even complexion with consistent use.

We love that this product is available at your local drugstore, relatively affordable, and highly effective. Over time, we noticed asignificant improvement in the radiance of our complexion. After six weeks, our skin appeared brighter and smoother. We also saw anoticeable difference in the firmness of our skin.

As for the texture of the product, it’s not liquidy nor oily; rather, it almostfeels like a lightweight paste.While this might not sound super appealing, itspreads easily and sinks into the skin quickly. We also appreciated the squeeze-tube packaging, which made dispensing the right amount of product easy. The one con we found is that, unlike some other vitamin C serums that immediately leave the skin looking radiant due to oily or luminous formulas, this one doesn’t. But given how effective it is over time, this isn’t a major downfall.

Who Its For

This is a great all-rounder for anyone in need of a radiance boost, though it’s best for those with a bit of patience, asresults may take time.

Other Options We Tested

Sunday Riley C.E.O. 15% Vitamin C Brightening Serum

Despite enjoying the results of this popular vitamin C serum, our tester had trouble recommending it because there are other more affordable options on the market that yield the same results.

Though this brightening serum did a nice job of boosting the radiance of our tester’s skin, she didn’t see an improvement in hyperpigmentation or firmness after the six-week testing period.

What to Look For in a Vitamin C Serum

Opaque Packing: Vitamin C is inherently unstable and quickly broken down when exposed to light and/or oxygen. For that reason, board-certified dermatologist Jessie Cheung, MD suggests looking for a product that comes in an opaque bottle—like the SkinCeuticals CE Ferulic Serum or the Klur Brilliant Light—or have an air-tight pump dispenser. Similarly, always make sure to store your vitamin C serum in a cool, dark place.L-Ascorbic Acid: To get the most value from your vitamin C serum, Dr. Cheung suggests looking for this type of vitamin C, the most potent and active version. That being said, it is often pricey and comes with the highest likelihood of irritation. Other less intense versions include sodium ascorbyl phosphate and magnesium ascorbyl phosphate. Skinceuticals C E Ferulic is a great option with L-ascorbic acid as is the CeraVe Skin Renewing Vitamin C Serum.Other Antioxidants

: Vitamin C works synergistically, meaning it plays very nicely with other antioxidants. Common antioxidants found in vitamin C serums include vitamin E and ferulic acid, says Dr. Cheung. In particular, she says these two increase the efficacy of vitamin C and help stabilize it. The Klur Brilliant Light is a great option that includes vitamin E.

FAQ

What does vitamin C serum do?

According to board-certified dermatologist Jennifer Herrmann, MD, vitamin C has three main functions. The first is protecting against environmental stressors and free radicals, an antioxidant benefit that slows signs of aging and reduces damage overall. Vitamin C also promotes collagen production, giving skin more support and structure. Finally, it’s a radiance-boosting agent, so a serum that features it can work to even skin tone and fade hyperpigmentation.

When should you apply vitamin C serums?

There has been much debate about whether it’s better to use the ingredient to protect skin during the day, or replenish it at night, but Dr. Herrmann says you can choose which time of day to apply— just be consistent.

How should you apply vitamin C serums?

Dr. Herrmann recommends applying your serum after cleansing. Additionally, avoid using it at the same time as certain other active ingredients such as benzoyl peroxide. For example, if you use a benzoyl peroxide product at night, it’s best to apply your vitamin C serum in the morning.

How often should you apply vitamin C serums?

According to Dr. Herrmann, you should apply vitamin C serum either daily or every other day, depending on your routine and the result you want. If you already alternate several other actives, you might apply it every other day; if you’re looking to dramatically fade hyperpigmentation, you may want to use it daily.
