10 Best Vitamin C Serums We Tested 2025, Dermatologist-Approved
All products featured on Glamour are independently selected by our editors. However, we may receive compensation from retailers and/or from purchases of products through these links.
Iâve been a beauty editor and writer for nearly a decade, so take it from me when I say that the best vitamin C serums are my secret weapon to minimizing dark spots, hyperpigmentation, acne scars, and getting my glow on all year-round. What exactly does the ingredient do, you might wonder? Vitamin C works against free-radical damage from the environment or sun, meaning itâs great for antiaging. Itâs also widely touted by dermatologists as one of the key ingredients for brightening, plumping, and protecting skin all at once.
To help you find the right formula for your skin type, Iâve tested dozens of vitamin C serums myself, and tapped dermatologists and Glamour editors for their favorite picks. During this time, we evaluated everything from consistency and scent (itâs known to smell, well, kinda funky), plus short- and long-term efficacy. Our top pick overall is the SkinCeuticals C E Ferulic, a formula that Iâve personally used for more than three years. Though Iâve tried over a dozen options, I always come back to this one for its brightening effectsâeven though itâs on the pricier side. If you want something cheaper that offers similar results, I love e.l.f.’s new launch, the Bright Icon Vitamin C + E + Ferulic Serum, which has a potent blend of similar ingredients. We also reviewed top-rated options that address a variety of skin concerns from acne to dryness and more.

How we tested the best vitamin C serums
We tested the best vitamin C serums for glowing skin by evaluating three categories: ingredients, format and texture, and long-term efficacy.
We started with about 25 of the most popular vitamin C products, all recommended by dermatologists and Glamour editors and testers. We narrowed down this list to 15 total products based on their availability, ingredients, and recommendations from dermatologists, then had our editors rigorously test them over the past year. During this time we evaluated everything from consistency to scent, plus monitored both short- and long-term efficacy. We also tapped dermatologists for tips to understand how to get the most out of these serums. The best vitamin C serums met the following criteria:
Best Overall: SkinCeuticals C E Ferulic

What we love: Offers visible results a lot faster than other vitamin C serums because of its three hero ingredients; can be used every morning; pleasant consistency that absorbs quicklyWhat could improve: Pricey; has that traditional vitamin C smell that some find unpleasantTLDR; This vitamin C serum is best for someone who can splurge on an efficacious formula that will minimize discoloration and dark spots with continued use.This top-selling vitamin C serum is considered one of the best by dermatologists. Morgan Rabach, MD, a board-certified dermatologist in New York City, likes that it packs the perfect triple threat against damage: L-ascorbic acid (15%), vitamin E, and ferulic acid. Kenneth Howe, MD, a board-certified dermatologist in New York City, says this particular skin care product âdelivers the greatest amount of antioxidant power of any product availableâ thanks to its careful combination of activesâwhich is reflected in the price, but you get what you pay for (and then some).
Our testerâs review: âIâm rarely one to splurge like this on a beauty product, but I truly think SkinCeuticals C E Ferulic is worth its weight in gold. Iâve been using the product on and off for a number of years (at least three!) and can really see a difference, particularly in the tone of my skin, when Iâm consistent. My skin skews dry, and this product helps take that dull look away, making my skin look overall brighter and more hydrated. Like most vitamin C serums, it does have a bit of a stink and that deep amber color that comes along with it, but it doesnât bother me all that much and certainly doesnât linger. As far as consistency and absorption, the formula feels nice and silky on skin and readily sinks in, so you can move on with your morning skin care routine. Also, a little bit goes a long way, helping to justify the overall value here,â says Glamour contributor Brigitt Earley.

Itâs also less messy than a liquid serum thanks to its gel-cream consistency that absorbs in a snap, and Iâm a big fan of the fact that itâs a serum that contains both vitamin C and hyaluronic acid.â

On the downside, she says, âthe added fragrance may not suit sensitive skin types.
Our testerâs review: âThis vitamin C serum is one of my favorites that I always turn back to,â says Glamourâs Kilkeary. âIt has a silky texture that sinks right into the skin so thereâs no need for a ton of rubbing or patting, and it always makes me look radiant and fresh.â She also likes that it doesnât have a funky smell and has a thicker consistency she finds easier to work with. âIâve used this serum on and off for about two or three years now, and I definitely think itâs played a part in how much clearer and even-toned my skin looks to this day.â

I would highly recommend this one if youâre just starting to dip your toe into vitamin C, because it has a lot of other ingredients (read hyaluronic acid, tranexamic acid) that make your skin increasingly hydrated and even-toned, too.â

What we love: Great for those with acne-prone skin; no sticky residueWhat could improve: Lower concentration of vitamin C than some other productsTLDR: This more affordable serum is a great choice for sensitive or combination skin, according to one of the dermatologists we spoke with.âIt offers a balance between exfoliation (salicylic acid) and soothing properties (neurosensine), which can help improve skin texture and tone without irritation,â says Dr. Collins. And while more seasoned users may yearn for a heftier punch of the active ingredient, the lower concentration of vitamin C is ideal for newbies.
Our testerâs review: âWhenever I need to inject some life into my skin, I reach for this serum,â says Ariana Yaptangco, Glamourâs senior beauty editor. âIt gives me an instant glow thanks to the concentrated 10% vitamin C, while salicylic acid helps clear and minimize my pores.â
Best Vitamin C Serum for Mature Skin: Clinique Fresh Pressed Daily Booster With Pure Vitamin C 10%Clinique Fresh Pressed Daily Booster With Pure Vitamin C 10%
Original video from Charlotte Twine testing Clinique Fresh Pressed Daily Booster With Pure Vitamin C 10%
What we love: Single dose application to mix into moisturizerWhat could improve: Expensive; best used within 7 daysTLDR: This 10% booster can be mixed into your moisturizer to help even out mature skin concerns like melasma, hyperpigmentation, and age spots, and improve skin resilience altogether.A vitamin C serum can help address mature skin concerns like melasma, hyperpigmentation, and age spots. This 10% booster can be mixed into your moisturizer to help even out these areas of discoloration and improve skin resilience altogether.
âThe main character of this show is definitely the applicator, which, to keep the vitamin C âfresh pressed,â has to have a foil lid removed and a button pressed, then be shaken for 15 seconds. Then you combine it into your daily moisturizer. I did this on the back of my hand, and the rich serum made my moisturizer feel more silky and luscious, and provided an instant gleam and a plumpness to my complexion once applied. Once you get the hang of the applicator, the mixed-in booster does make for a convenient way amp up your skin care routine for aficionados who donât want to layer in yet another serum,â says Glamour contributor Charlotte Twine.
Best Budget: The Ordinary Vitamin C Ascorbyl Glucoside Solution 12%The Ordinary Vitamin C Ascorbyl Glucoside Solution 12%
Original video from Alanna Martine Kilkeary testing The Ordinary Vitamin C Ascorbyl Glucoside Solution 12%
What we love: The price; the consistency; efficacy after just a few usesWhat could improve: The smell isnât greatTLDR: The serum contains a whopping 12% vitamin C for effective antioxidant protection at under $20, which makes us huge fans.You wonât want to skip out on this pick from The Ordinary that works to even out and protect the skin. The formula is a lightweight clear gel that absorbs upon contact, and weâve found it to be just as effective as some of the more expensive options on this list.
Our testerâs review: âI really liked this formula from the minute I tried it,â says Glamourâs Kilkeary. âMy skin simply drank it up, and I noticed less discoloration in my problem areas (especially around my nose) after using it for around two weeks. The only critique I have is that the smell isnât the best, but between the price and how well it works, thatâs easily forgivable.â
Best Value: e.l.f. Cosmetics Bright Icon Vitamin C + E + Ferulic Serume.l.f. Cosmetics Bright Icon Vitamin C + E + Ferulic Serum
Original video of Alanna Martine Kilkeary testing the e.l.f. Cosmetics Bright Icon Vitamin C + E + Ferulic Serum
What we love: Has a potent blend of vitamin C, E and ferulic acid for under $20What could improve: StickyTLDR: If you want to reap the benefits of a vitamin C serum with ferulic acid without spending over a hundred dollars, this under $20 serum is just as effective at minimizing discoloration, hyperpigmentation and dark spots.Although this serum is a bit heavier and slightly stickier than the luxury vitamin C with ferulic acid on this list, it definitely gives the expensive formulas a run for its money when it comes to efficacy. It manages to target dark spots, fine lines and dullness, and gives you an almost instant radiance in just a few uses.
Our testerâs review: âIâm a long time fan of the more expensive vitamin C plus ferulic acid serum on this list, so I was skeptical to try this cheaper version. Itâs definitely a bit more goopy than the OG, but I was particularly impressed with how well it worked. The acne scars that like to hang out around my nose and chin look a lot less noticeable after trying this for a few weeks, not to mention, my skin has an overall glow that actually shines through my makeup a bit all day. Needless to say, Iâm pleasantly surprised,â says Glamourâs Kilkeary.
Best for Dry Skin: YSE Beauty ââVitamin C Brightening SerumYSE Beauty ââVitamin C Brightening Serum
Original video from Alanna Martine Kilkeary testing YSE Beauty ââVitamin C Brightening Serum
What we love: Silky texture; skin absorbs the product easily; gives a nice glowWhat could improve: PriceyTLDR: Fighting both dry skin and hyperpigmentation can feel like an uphill battle, but this antioxidant brightening serum both hydrates and evens out texture and tone.This pick has a blend of vitamin C, niacinamide, squalane, and hyaluronic acid to help address dark spots and areas of discoloration, and it makes your skin feel soft and plump.
Our testerâs review: âI deal with hyperpigmentation and acne scars around my nose and on my chin, so Iâm always on the hunt for a serum to help mitigate the discoloration. I find that sometimes vitamin C serums or other brightening exfoliants tend to dry my skin out a lot, especially in the colder months, so I was excited to see that this one addresses both dryness and discoloration,â says Glamourâs Kilkeary.
Other vitamin C serums we tested:
Drunk Elephant C-Firma Fresh Vitamin-C Day Serum: Glamourâs Kilkeary notes that this is best for those already well-versed in skin careânot only for its potency, but also because you have to mix the formula together yourself before getting started. âThis pick comes with the formula in two separate piecesâa liquid and powderâthat you have to compound together to create your serum,â she says. âItâs certainly a fun little experience, but you have to make sure the serum is really mixed well to ensure that itâs actually effective.â But boy, does it work, she says. âMy skin drank it up, and I was pleased with how glowy I looked after application, which was a major plus,â she told me. âIn the long-term, I found this one gave me a more even-toned and overall brighter complexion.â On the downside, she found the smell off-putting and the texture a bit sticky.The Inkey List 15% Vitamin C & EGF Brightening Serum: âIâve had this vitamin C serum on my radar for quite some time now, and while Iâve only used it regularly (in both a.m. and p.m.) for about a week now, thereâs already a lot I love about it. While I canât speak to long-term results just yet, I love the consistency of the product. Itâs a clear liquid that has cooling effects upon application, which wakes up skin, especially first thing in the morning. And despite the fact that itâs very liquidy and a little goes a long way, it absorbs very quickly, so itâs not messy to work with. Skin feels soft and silky while it absorbs rather than tacky or wet. I also appreciate the lack of smellâitâs nothing funky, but itâs not overtly fragrant either,â says Earley.COSRX Pure Vitamin C 23% Serum with Vitamin E & Hyaluronic Acid: This anti-aging pick has a blend of 23% vitamin C, vitamin E and hyaluronic acid and is not here to mess around. It will even out your complexionâs skin tone and help minimize dark spots quickly, not to mention, youâll also see an improvement in your skinâs elasticity (think: fine lines and wrinkles) after regularly incorporating it into your routine.Youth to the People 15% Vitamin C + Caffeine Energy Serum: This vitamin C serum is particularly good for dry skin types thanks to gentle fruit extracts and squalane that help lock in moisture for hours. Glamourâs Kilkeary could go on and on about how it instantly energizes and depuffs her face. âOn mornings when Iâm looking particularly red or puffy, I always reach for this serum to help even out my skin tone and texture. Itâs a lightweight gel that absorbs into the skin basically upon contact, and it never makes my other skin care or makeup products pill, which is a huge plus.âPaulaâs Choice C15 Super Booster: Charlotte Birnbaum, MD, a board-certified dermatologist at Spring Street Dermatology in New York City, recommends this for younger patients who are looking to introduce the ingredient into their skin care routines. It has 15% vitamin C in the formula, which is less than the usual 20% we see in other options. Glamour contributor Leilani McQuay is in her 30s and likes to keep her skin care routine minimal because of her dry and acne-prone skin. âThe bottle features a dropper, so itâs easy to dispense the right amount,â she says. âAnd even though the consistency was a bit watery, it felt very hydrating and absorbed nicely into my skin.âTruSkin Vitamin C Facial Serum: Glamour senior commerce editor Jenifer Calle approached testing this Amazon pick with trepidation but was pleasantly surprised by how well this affordable vitamin C serum worked. âI know this antioxidant has a ton of skin care benefits (namely, brightening skin and minimizing dark spots), but Iâve never noticed any major improvements when using it in the past. I thought the same would be the case for this TruSkin product. But after more than four months of consecutive testing, I can see itâs actually been workingâalbeit slowly.â She used the recommended five drops every morning on a clean dry face before proceeding with the rest of her beauty routine (toner, moisturizer, and sunscreen). âI noticed my overall complexion did look brighter and my skin felt smoother. Itâs not like my freckles or dark spots completely disappeared, but thereâs no denying my skin looks more radiant, especially in the mornings.â A nice bonus? Calle says this product doesnât have the same off-putting smell as others sheâs tried in the past. It was also quick to absorb and entirely nonirritating. âI donât have extremely sensitive skin, but harsh products tend to cause redness. Iâm happy to report that I didnât experience any itching, burning, or redness.âInnisfree Green Tea Enzyme Vitamin C Brightening Serum: If youâre looking for a Korean vitamin C serum that will help minimize redness and post-acne marks, we love this brightening pick. âFun fact: Innisfree was one of the very first K-beauty brands I tried, and this vitamin C serum remains one of my favorite products from their lineup. I love its glow-boosting properties and the fact that, despite its potent formula, it doesnât irritate my skin whatsoever,â says Glamour contributor Denise Primbet.RoC Multi Correxion Revive + Glow Daily Serum + Vitamin C: Glamourâs Calle uses this vitamin C serum when traveling. âThis is a tiny but mighty vitamin C serum. I like to carry it in my travel bag because itâs so small. But trust me, itâs effective. I feel like my skin is radiant when Iâm using it, and it layers well under makeup, which is great because I have oily, combination skin.âFrequently asked questions
Vitamin C is an antioxidant, and our bodies need it to function properly. You might associate it with citrus fruits like oranges, lemons, kiwis, and grapefruit, but its health perks extend to your skin too.
In terms of skin care, when ultraviolet light penetrates your skin, it causes lasting damage by producing free radicals. Vitamin C can prevent that damage by âquenchingâ the free radicals as they form, says says Kenneth Howe, MD, a board-certified dermatologist in New York City. The brightening serum also inhibits a key enzyme in melanin production, so it can act as a dark spot corrector too. The end result? A more radiant complexion and smoother texture over time. (Think glass-like skin.)
What does vitamin C serum do?
âVitamin C helps defend against free radical damage caused by environmental stressors like UV exposure and pollution,â says Corey L. Hartman, MD, a board-certified dermatologist and founder of Skin Wellness Dermatology in Birmingham, Alabama. âVitamin C also aids in reducing hyperpigmentation and dark spots caused by acne scarring or sun exposure. Research has also shown that vitamin C helps stimulate collagen production, which makes skin appear firmer and reduces the appearance of fine lines and wrinkles.â
What to look for in a vitamin C serum
The key ingredient in these serums is L-ascorbic acid, a pure form of vitamin C, says Joshua Zeichner, MD, a board-certified dermatologist in New York City. This type of serum penetrates more deeply than other forms, making it more likely to reach the layers of skin where you actually need it to work. Another popular one? Tetrahexyldecyl ascorbate, which tends to be more stable than its counterparts (read âit lasts longerâ).
Pay attention to the concentration too. âLook for serums that contain 10% to 20% vitamin C,â says Morgan Rabach, MD, a board-certified dermatologist in New York City. âLess than 10% is not as effective, and over 20% can cause skin irritation.â A supporting cast of active ingredients, such as vitamin E and ferulic acid, can also boost its efficacy. Some vitamin C serums may even boast nice-to-haves including hyaluronic acid, squalane, and other hydrators.
In addition, peep the packaging that houses any vitamin C products youâre considering. Vitamin C is notoriously unstable, so it can oxidize with light and heat. You want darkly tinted glass bottles with airless delivery, since air can also cause pure vitamin C to degrade, says Dr. Rabach.
When to use vitamin C serum
âI recommend using vitamin C serum in the morning, once daily, followed by face sunscreen,â says Dr. Hartman. Because vitamin C is a powerful ingredient, itâs best to separate usage from other strong ingredients, like retinol. âTry your retinol during your evening skin care routine and a vitamin C product in your a.m. routine,â says Dr. Hartman. âDoing so will ensure you get the maximum benefit without risking irritation.â
How often should you use vitamin C serum?
We know you want to see results right away, but for the most dramatic outcome, you really need to use vitamin C serum daily, targeting one application each morning, for a number of weeks. Remember to always follow the application with sunscreen. And if you have an allergy or experience a reaction such as burning or stinging, you should avoid putting the product on your face, says Nava Greenfield, MD, a board-certified dermatologist at Schweiger Dermatology in New York City.
What percentage of vitamin C should you look for?
According to Brooke Jeffy, MD, a board-certified dermatologist based in Arizona, you should start with a vitamin C in the 5% range and build up your tolerance to something stronger (up to 20%). âStronger percentages will be more likely to cause irritation, so itâs best to start lower,â she says.
How to apply vitamin C serum
Apply vitamin C serum once daily in the morning after cleansing your skin. Consult package directions for specifics, but in general, put a few drops of serum into your palm and pat it onto your face. Allow it to sit for a few minutes for maximum absorption. As mentioned, always follow with a broad-spectrum face sunscreen with SPF 30 or higher since vitamin C becomes unstable when exposed to light.
Does vitamin C serum expire?
Vitamin C serums do expire, typically within three to six months after opening (but always check the product label for specific guidelines), says Dr. Collins. âVitamin C [ascorbic acid] is highly sensitive to light, air, and heat, which can lead to oxidation,â she explains. âOnce oxidized, the serum turns a brownish or yellowish color and becomes less effective at delivering its skin-brightening and collagen-boosting benefits. Oxidized vitamin C may even cause skin irritation for some individuals.â
To maximize the shelf life of your vitamin C serum, choose a product with opaque or airless packaging, and store it in a cool, dark place. Formulations that stabilize vitamin C (like our top overall pick, which is combined with ferulic acid) also tend to last longer than pure vitamin C.
Can you use niacinamide, retinol, or other acid serums with vitamin C products?
Yes, you can use the niacinamide serums with vitamin C products. Overall, vitamin C pairs well with other popular skin care ingredients, says Dr. Hartman. âVitamin C pairs well with niacinamide, caffeine, vitamin E, ferulic acid, and hyaluronic acid. I recommend looking for vitamin C products with complementary active ingredients to get the most bang for your buck.â
On the other hand, vitamin C does not pair well with retinol or alpha hydroxy acids (AHAs) such as glycolic acid and lactic acid. âMost people use a vitamin C serum in their morning routine, so leave the retinol creams and AHAs for your evening skin care,â says Dr. Hartman.
Does vitamin C help with acne and acne scars?
Vitamin C doesnât help with acne, says Dr. Hartman, but âit can minimize redness and post-inflammatory hyperpigmentation from acne.â
Are vitamin C serums effective for dark spots?
Vitamin C serums can be effective for dark spots, when combined with other dark-spot fighting ingredients like niacinamide or tranexamic acid, according to the dermatologists we spoke with.
