17 Best Vitamin C Serums, Tested and Reviewed for 2024

I've been using this vitamin C serum religiously since 2020. It legit checks every single box. The formulation is oil-free (which my oily, acne-prone skin loves) and uses the ideal combo of l-ascorbic acid, ferulic acid, and vitamin E to help slowly fade my acne scars and fight off free radical damage and pollution that can lead to fine lines. But most of all? It's hella affordable, at less than $35 a bottle.

I just pat it on my skin after toner in the morning. It gives my skin a ridiculous glow, but it doesn't feel greasy or heavy at all. Then, I'll layer on a moisturizer with SPF and be on my merry way—bright, dewy skin and all!

• Fragrance free? Yes

Glowing customer review: "I just started going through menopause and my skin has been just blech. Boy, I’m glad I purchased this. My skin has never looked this bright or felt so good. My dark spots have lightened up as well. My mom even said my skin is so bright and looks so healthy."

Annoyingly, most vitamin C serums I've tried have broken out my extremely acne-prone skin (they often are filled with moisturizing oils, which is great for dry and sensitive skin; bad for my personal pores). But this one actually blends L-ascorbic acid with salicylic acid, a beta-hydroxy acid that's oil soluble, meaning it can go into your pores to help dissolve the gunk and oil that tends to clog them and cause zits. It's not called the GOAT for acne for nothin'.

In this formula, the two work together v well to brighten your skin. Salicylic acid helps give you clearer pores, which can make them look a bit smaller and give your entire face a brighter look. Plus, for the lazy ppl out there (hi, it me), you only need one product to target both acne and wrinkles in the morning. We love to see it.

Glowing customer review: "I really like this. It was a little sticky at first, but absorbed right into my skin. It didn't burn or anything like that. My skin felt soft and moisturized, but also my pores seemed smaller."

You cannot scroll on Reddit without finding a mention of this affordable vitamin C serum. Literally. I read so many threads, and this one came up every single time. And after testing, I totally get why. This formula is loaded with a v-potent 20 percent dose of vitamin C, which majorly brightened my skin after a few months of use. Plus, it's also got the O.G. vitamin E and ferulic acid combo we all love to help boost the line-smoothing, antioxidant power. Redditors (and me!) swear it's a great option to try if you love Skinceuticals C E Ferulic but wanna spend a lil less cash.

Glowing customer review: "I am 50 years young and I’ve been working on all the dark spots on my face due to tanning in my younger years. This product has been very effective. My face is brighter and I’ve noticed it has reduced a lot of my dark spots. Some of them have completely disappeared. It’s a YES for me."

One of my besties said once that she'd literally sell her kidney if it meant she'd alway be well-stocked with this vitamin C face oil. Obviously, her comment made me try it immediately, and yup, I get the hype. This oil gives my skin a major glow, whether I slather it on right before sunscreen in the morning or as the last step of my routine in the evening.

This formula actually contains a less common form of vitamin C, tetrahexyldecyl ascorbate. It's a stable form of vitamin C that has a lot of promise in its ability to absorb well into your skin to boost collagen and brighten and protect skin (but it's gotta be studied more). Because of all this, it's likely a lot less irritating, which is great for those who typically find vitamin C serums to be a bit too much for their skin.

• Fragrance free? Yes* (*but contains essential oils)
• Skin types: Dry, some sensitive types
• Usage: Morning or night

Glowing customer review: "I’ve been using this oil for a year and ran out two weeks before the Sephora sale. Worst two weeks ever! I tried to use some leftover squalane from another brand, and it didn’t even compare. Finally got my new bottle and my skin feels hydrated and glowy again!"

Ask any dermatologist which vitamin-C serum they recommend to patients and personally use, and I guarantee you they’ll say it’s this one from SkinCeuticals. The serum is absolutely iconic, and contains L-ascorbic acid (one of the most stable, well-studied forms of vitamin C), as well as vitamin E and ferulic acid, which boosts the efficacy of the vitamin C. And very cool fact: The formula stays active for 72 hours after you dab it on, even after washing your face.

I've personally gone through multiple bottles of this formula over the years, because it gives my skin an immediate lit-from-within glow and helps keep my skin clear, plump, and bright over time.

But FYI: C E Ferulic isn't the best option if your skin is oily and/or acne-prone, warns Cosmo deputy beauty director Lauren Balsamo. But (!) no worries, because she actually swears by Skinceuticals Silymarin CF, a slightly reformulated version filled with vitamin C, ferulic acid, and salicylic acid to help curb breakouts and give your skin a healthy glow too.

• Fragrance-free? Yes
• Skin types: Dry, combo

Glowing customer review: "This is hands down the best vitamin C serum I've used, and I've tried a range of different brands from The Ordinary to Drunk Elephant. CE Ferulic is the only product that has made a difference in my hyperpigmentation and dark spots. The texture goes on smoothly and is absorbed by my skin quickly, making it easy to integrate into my routine."

Another cult-favorite formula, this vitamin C serum with 20 percent l-ascorbic acid and antioxidant-rich green tea extract is a must for brightening, smoothing, and firming skin. Plus, it’s free from skin irritants (like synthetic fragrances or dyes, drying alcohols, and essential oils). I personally like to smooth it over clean skin each morning (the gel-like texture layers perfectly under SPF and makeup products) as the first step in your skincare routine.

Glowing customer review: “I have tried so many vitamin C serums over the years and none compare to BeautyStat. I have some discoloration as well as melasma and this has made a world of a difference. It’s easy to apply and isn’t sticky or uncomfortable—plus, it layers well with my other skincare.”

"I kept seeing rave reviews of this vitamin C, so I decided to test it out and let me just say wow, I'm so glad I did," says deputy beauty director Lauren Balsamo. "The ultra gentle—yet effective!—formula is now a regular in my skincare lineup." It’s filled with vitamin C, turmeric, kojic acid, and fruit enzymes to fade dark spots, melasma, and post-inflammatory hyperpigmentation from old breakouts. And unlike many vitamin C serums that be too intense for certain skin types and tones, this one is formulated to be used by all, which is something you rarely see in the skin world.

Glowing customer review: “This serum is amazing. My skin is so glowy after using it and I have dry skin that tends to get dull. I am able to wear it in the day time with SPF and have no issues with burning on my sensitive skin.”

"PCA Skin’s C&E Advanced is one of my favorite vitamin C serums," says licensed aesthetician Candice Miele. “It has a creamy texture that’s hydrating but dries down to a matte finish, and the 20 percent l-ascorbic acid is fantastic for brightening dark spots and evening out your skin tone.” In my testing experience, the formula layers beautifully under SPF and makeup and really helps improve discoloration since it's combined with other brightening ingredients like hexylresorcinol and protective antioxidants like vitamin E and silymarin.

Glowing customer review: “Right away I was very pleased with how this felt on my skin, it's not sticky or tacky and it leaves a matte finish after application that feels tightening in a really good way. It absorbs fully into the skin, which gives me confidence that it is getting to work. I feel as though I am already noticing a reduction in redness and discoloration, as well as the fading of a scar I have long wanted gone."

If you’re dealing with sensitive skin or chronic redness, this ultra-gentle vitamin C serum is about to be your new go-to, thanks to its added vitamin E, colloidal oatmeal, and feverfew extract. Together, these ingredients help soothe skin and reduce inflammation while providing a brightening effect. Use it every other morning on clean, dry skin if your skin is ultra-sensitive.

Glowing customer review: “My skin has not liked other vitamin C products I have used in the past. This one is great for my sensitive skin. I have seen a difference on my dark spots on my chin.”

This is a high-potency serum that visibly brightens, hydrates, and plumps skin, says Miele. The hardworking combo of vitamin C, hyaluronic acid, and peptides stimulate collagen, hydrate skin, and smooth the look of fine lines for a supremely dewy glow.

Glowing customer review: “I started to use this product two years ago and I have seen great results in my skin. I use it day and night and it's helped me a lot with hydration and wrinkles."

This powerful serum combines vitamin C with glycolic acid (a potent AHA that helps boost cell turnover and get rid of dead skin cells) to make your dark spots lighter, your pores smaller, and your skin surface smoother and more even. It's one of the few vitamin C serums I've tested that successfully lightens dark spots *and* makes the rough, bumpy texture on my cheeks and chin less noticable.

Glowing customer review: “This product by Murad is the best stuff I ever used on my face. It smells so good but more importantly it really works. I’ve had several people tell me my face looks brighter. 5 stars for an amazing product."

You don’t need to spend a ton of money or hit up some fancy med spa to find a vitamin C serum that gives good results. This option from drugstore skincare brand CeraVe is accessible, oil-free, and contains 10 percent l-ascorbic acid to brighten your skin tone, says dermatologist Elyse Love, MD. And because it’s made with barrier-boosting ceramides and hydrating hyaluronic acid, it’s a safe choice for sensitive skin types too.

Glowing customer review: “This vitamin C serum is one of those products that I can honestly say makes a difference with my skin. My skin looks brighter and better and my dark spots and sun spots are less noticeable too.”

If your skin is too sensitive for a retinol face cream or serum but you still want the tightening and smoothing benefits, try this firming vitamin C serum from Dr. Dennis Gross. It uses 15 percent vitamin C to help repair and rebuild collagen—a protein that is naturally found in skin and is responsible for skin firmness and plumpness—plus lactic acid to nix dead skin cells and smooth the surface your skin.

Glowing customer review: “I love this vitamin C serum. It’s really helped to brighten my skin and has made it more firm too. The packaging is so pretty too. The quality is the best!!”

This vitamin C serum is def on the pricey side, but the formula is truly as effective and science-backed as they come. “The gentle, oil-free formula combines a stable form of vitamin C (tetrahexyldecyl ascorbate) with vitamin E and 17 additional antioxidants to decrease redness and discoloration,” says Dr. Love, who adds, “The formula is suitable for sensitive and rosacea-prone skin unlike other vitamin C's on the market.” I love using this under water-resistant sunscreen with SPF 50 on days that I'm exercising outside and it's been incredibly helpful at protecting my skin from environmental damage.

• Usage: Morning and night

Glowing customer review: "The serum is worth every penny, IMO. It’s never once irritated my skin and I’ve noticed a clear difference in my dark spots and overall skin tone after using it for a month."

At just $15, this is the least expensive vitamin C serum on the list—but it’s by no means the least potent. The formula combines 15 percent ascorbyl glucoside (a stable form of vitamin C) with plant-based epidermal growth factors to fade dark spots and marks and minimize lines and rough texture.

Glowing customer review: “I have been using this for a few months now, and I really like how it’s brightened my face. Plus, it’s very affordable and the tube lasts awhile.”

You don’t have to switch up your existing skincare routine just to incorporate some vitamin C. Mix a few drops of this vitamin C booster serum into your face moisturizer or SPF (in my testing experience, it blends perfectly with cream-based formulas) to give your skin some added protection against UV damage and pollution.

• Fragrance-free? Yes
• Skin types: Dry, combo, oily
• Usage: Morning and/or night

Glowing customer review: “This is so easy to use and mix with my other skincare products. It has no added fragrance and doesn’t irritate my skin either.”

Before you splurge on a pricey peel or a laser treatment (like Fraxel or Clear and Brilliant) to get rid of your dark spots, give this brightening vitamin C serum a try. It quickly fades surface discoloration and dark spots while providing your skin with much needed antioxidant protection against free radical damage,” says licensed aesthetician Brittany Blancato. “It’s a product that I can count on to do exactly what its supposed to do: give your skin an even-toned glow and protect it from future damage.”
