In fact, the dermatologist we consulted said it’s the “OG of antioxidants.”
The ultra-powerful nutrient, impressively, is incorporated into many types of skincare and, like an Oreo, is the “good stuff” in the middle (following your best cleanser and preceding your creamy moisturizer, of course).

“Serums are great because they are vehicles for the actives that you use on your skin for intentional skincare — the practice of using a product to make a change in your skin,” board-certified dermatologist and founder of Visha Skincare, Purvisha Patel, MD, told the Post.
Best known for its natural brightening effects, vitamin C has been put through clinical trials and proven to aid in a variety of feel-good benefits, too, which Dr. Patel outlines — along with everything to know about using a vitamin C serum — ahead of listing the best vitamin C serums we tested.
Be sure to check out our in-depth FAQ section for more.
Best Overall: TruSkin Vitamin C Serum
The TruSkin Vitamin C Serum isn’t only a celeb favorite that has garnered more than 10,000 purchases in the past month but it’s the trifecta of vitamin C serums for the face. It contains hyaluronic acid and vitamin E, and I noticed a quick brightening effect from the first time I started using the super-serum.
More than 145,000 shoppers rave about this product, and I can see why. It helped even out my skin tone, so much so that it’s one of my go-to products each morning because I don’t feel like I have to wear any foundation! (It’s a large mountain to climb for a skincare product to reach that level.)
Additionally, it’s fragrance-free, contains skin-loving nutrients and has a thoughtfully curated ingredient list. To top it all off, it absorbs quickly and is a cosmetically elegant vitamin C serum that is an incredible option for less than $40.
Key Ingredients: Sodium Ascorbyl Phosphate (gentler on the skin than L-ascorbic acid), Hyaluronic Acid, Aloe Vera | Size: 1 fluid ounce
Best Budget: Olay Vitamin C + Peptide 24 Serum
Don’t skip the drugstore. The Olay Vitamin C + Peptide 24 Serum is proof that you can pick up an ingredient-first formulation that’ll do what it’s intended.
This product is an iconic skin brightener that led to noticeable results. It contains peptides to create that bright, bouncy effect, along with lactic acid to help eliminate that unwanted dull skin feeling. It’s no B.S., a great price, and excellent to use daily.
Key Ingredients: Vitamin C, Vitamin B3, Lactic Acid | Size: 1.3 fluid ounces
Best Splurge: Dr. Barbara Sturm The Good C Vitamin C Serum
If I could bottle up Dr. Barbara Sturm’s The Good C Vitamin C Serum and take it with me everywhere, I seriously would.
Though up there in price, this serum is impeccable and has a luxurious quality I didn’t know existed. Featuring aloe vera, hyaluronic acid and vitamin C — the major triage of skin soothers, per dermatologists — it’s best designed for sensitive skin types.
Key Ingredients: 5% Vitamin C, Zinc, Aloe Vera | Size: 1 fluid ounce
Best L-Ascorbic Acid: SkinCeuticals C E Ferulic with 15% L-Ascorbic Acid
Meet the cult-favorite of all vitamin C serums. SkinCeuticals’ C E Ferulic with 15% L-Ascorbic Acid is a tried-and-true favorite of many and it made our cut because of its inclusion of L-Ascorbic Acid — the most tangible form of vitamin C.
It feels incredibly raw and real when using, as if a dermatologist was dispensing the best of the best onto my skin at the clinic. It made my skin truly glisten and the on-the-dot application was one of the best I’ve seen.
Key Ingredients: 15% L-ascorbic Acid, 1% Alpha Tocopherol, 0.5% Ferulic Acid | Size: 1 fluid ounce
Best for Bouncy Skin: Sunday Riley C.E.O. Glow Vitamin C + Turmeric Face Oil
“I have been repeat purchasing the C.E.O Glow serum from Sunday Riley for several years now,” Jackie Goldstein, VP of commerce, shared about using the formula religiously. “I love the smell, I find the texture just right, and after I’ve used it, my skin immediately looks brighter and healthier.”
The oil itself has turmeric and vitamin C as its dominant ingredients, the turmeric helping to give its “glow” orange color. “A little goes a long way, so it lasts a while, which is good because I don’t love the price point. It’s discounted fairly often, so you should try to catch it on sale,” Goldstein added. “Either way, you won’t be disappointed. The consistency of the product is kind of like a thicker olive oil with more heft (it’s not going to roll right off your face!).”
Each morning after washing her face, Goldstein uses about a half-dime sized blob of it, followed by a moisturizer and of course sunscreen, which is necessary with vitamin C. Oh, and other Post Wanted editors are obsessed (myself included!)
Key Ingredients: Vitamin C (THD Ascorbate), Turmeric, Evening Primrose Oil | Size: 0.5 or 1.18 fluid ounces
Best Cruelty-Free: Mad Hippie Vitamin C Serum
If you’re aiming to be mindful with your next vitamin C serum purchase, the Mad Hippie Vitamin C Serum is both cruelty-free and won’t break the bank. How great is that? With a purposeful formulation containing ferulic and hyaluronic acids, it’s an incredible skin hydrant, too.
More than 4,000 shoppers purchased this skincare superstar on Amazon alone, which speaks to its great quality. It contains antioxidants, is excellent for anti-aging, giving my skin a youthful and natural glow whenever I use it. Overall, it’s a wonderful brightener and one of my most-used on this list.
Key Ingredients: Vitamin C, Konjac Root, Hyaluronic Acid, Ferulic Acid | Size: 1.02 fluid ounces
Best for Hyperpigmentation: Glow Recipe Guava Vitamin C Dark Spot Serum
Glow Recipe’s Vitamin C Dark Spot Treatment Serum isn’t worth the buy merely for its pretty pink packaging and the word “glow” in its name. This is the crème de la crème of serums to help correct hyperpigmentation — it nourished my skin and left it balanced with no irritation.
Not only does it come out pink (!!!) but it’s also a certified Clean at Sephora product, vegan and includes guava, tranexamic, ferulic acids and five forms of vitamin C to naturally brighten the skin.
Key Ingredients: Vitamin C, Ferulic Acid, Vitamin E | Size: 1 fluid ounce
Best for Beginners: The Ordinary Ascorbyl Glucoside Solution 12%
What I love most about The Ordinary is its accessibility while still proving effective on the skin. Each of its serums are like little beauty potions that are difficult to ignore. Enter the Ascorbyl Glucoside Solution 12%, a skin brightener with a keen focus on anti-aging and allowing the skin to feel revitalized. I love its silky consistency which is impressive for its less-than-$20 price point.

What’s more, its water-based formula makes it easy to dispense and blend and it’s an option I consistently recommend to any beginner vitamin C serum users. Plus, it’s hydrating and non-irritating.
Key Ingredients: Vitamin C (Ascorbyl Glucoside), Vitamin C Derivatives | Size: 1 fluid ounce
Best for Sensitive Skin: Herbivore NOVA 15% Vitamin C + Turmeric Brightening Serum
When I first realized the Herbivore Botanicals NOVA 15% Vitamin C + Turmeric Brightening Serum existed, I jumped for joy. Turmeric is a superfood ingredient that my cousin adds to his oatmeal each morning, and I had a good hunch this formulation was going to be a “superfood” for my skin — and I was right.
Notably, this gentle vitamin C serum helps target dullness and dark spots, along with an uneven skin tone, bringing a cocktail of benefits to your skin’s surface. It’s worth every penny and a wonder for sensitive skin.
Key Ingredients: 15% THD Vitamin C, Turmeric, Arbutin (to help fade dark spots) | Size: 1 fluid ounce
Best for Dry Skin: CeraVe Skin Renewing Vitamin C Serum
Oh, CeraVe, how I love you so. I’ve been using the brand’s Hydrating Facial Cleanser ($15) for years and wasn’t surprised at the slightest when its Skin Renewing Vitamin C Serum was one of the ones to come up on top. Notably, its fresh scent just makes you want to use it every day.
It effectively brightened and nourished my skin. It hydrates where it’s supposed to and has a moisturizer-like effect. For less than $40, you can’t go wrong.
Key Ingredients: 10% L-ascorbic Acid, Hyaluronic Acid | Size: 1 fluid ounce
Best for Oily Skin: La Roche-Posay 10% Pure Vitamin C Serum
La Roche-Posay’s Pure Vitamin C Face Serum is delightful. I was impressed with its ability to instantly nourish my skin and absolutely loved its roller application that’s a step-up from the potion-like serum dispensers that tend to be too runny. It contains salicylic acid which is great for those with acne-prone skin.
This serum has a fresh scent that even those who prefer no fragrance would love. Oh, and I reviewed the lion’s share of La Roche-Posay, and this product is one of my favorite hero products from the brand.
Key Ingredients: 10% Vitamin C, Hyaluronic Acid, Salicylic Acid | Size: 1 fluid ounce
Best for Acne-Prone Skin: Drunk Elephant C-Firma Fresh Vitamin-C Day Serum
I’ve been one of Drunk Elephant’s No. 1 fans for years and have been using the C-Firma Fresh Day Serum regularly since I wrote a review on the product. It turns you into a bathroom mixologist and has one of the freshest, high-quality formulations yet.
Aside from its revitalized feel, it always leaves my skin plump and healthy, which is the ideal texture before catching those ZZZs. Better yet, you’ll notice some pesky blemishes dying down after only a few uses of this all-over skin brightening agent.
Key Ingredients: 15% L-ascorbic Acid, Ferulic Acid | Size: 0.94 fluid ounces
Best for Darker Skin Tones: Farmacy 10% Waterless Vitamin C Serum
When I first came across Farmacy’s 10% Waterless Vitamin C Serum, I knew I was going to like it. A serum that includes vitamin C and up-cycled tangerine peel? Sounds like facial heaven.
As someone with dry skin, this is the best for this skin type because it includes ascorbic acid and 1% alpha arbutin (a brightening active that targets dark spots) that nourished my skin to the T. Though it’s not the only serum in this edit that works well on dry skin, it’s a thirst-quenching one I kept resorting back to.
Key Ingredients: 10% L-ascorbic Acid, Upcycled Tangerine Peel, 1% Alpha-Arbutin + Ferulic Acid | Size: 1.01 fluid ounce
Best with SPF: Supergoop! Daily Dose Vitamin C + SPF Sunscreen Serum
Your vitamin C serum just got an upgrade. With the Supergoop! Daily Dose Vitamin C + SPF Sunscreen Serum, you don’t have to choose between a facial SPF and a vitamin C serum, or a makeup primer or a moisturizer. This versatile product is a little bit of everything, making it worth the cost.
Though holding a more moisturizer-esque consistency, the product is a staple in my routine whenever I want to cut down on some of the products I use. As mentioned, its multi-purpose formulation is both thoughtful and effective, and I love the natural glow I find after each use. Though not as satiny of a finish, it’s one of my top favorites on this list.
Key Ingredients: Vitamin C, SPF, Aloe | Size: 1 fluid ounce
Best Korean: COSRX The Vitamin C 23 Super Vitamin E + Hyaluronic Acid Serum
Glass skin, anyone? After reviewing COSRX, I can safely say that the brand behind the TikTok-viral snail mucin is worth every penny.
The Vitamin C 23 Super Vitamin E + Hyaluronic Acid Serum is another winning product from the brand that boasts a soothing, brightening nature that’ll have your skin baby-soft with each use. It helps dwindle down fine lines and uneven texture, refreshing the skin and rendering it less dull.
For the price, it’s a little bit of everything that’s one of the best in Korean vitamin C serum skincare. My thoughts? Purchase it alongside the Snail Mucin 96% Repairing Power Essence ($15). You won’t be sorry.
Key Ingredients: 23% Ascorbic Acid, Hyaluronic Acid, Vitamin E | Size: 0.7 fl. oz.
Best for Large Pores: Biossance Squalane + Vitamin C Dark Spot Serum
Biossance’s Squalane + 10% Vitamin C Dark Spot Serum features luxe packaging fit for your bathroom counter, but it’s what’s on the inside that counts.
It makes my skin look incredibly balanced and bright whenever I use it. This serum even had a firming effect near the outer corner of my eyes, which may be effective for anyone with crow’s feet. Additionally, its moisturizer-like consistency and impressive eradication of dark spots make it lovely for sensitive skin types.
Key Ingredients: 10% Vitamin C, White Shiitake, Squalane | Size: 1.01 fluid ounce
Best for Dull Skin: TULA Brightening Treatment Drops Vitamin C Serum
Tula’s Brightening Treatment Drops are literal drops of ocean-cool refreshment onto your skin. It’s the serum I would choose if I need to really wake up in the morning and over time, gives some of the best, glowy results.
Not to mention, this is one of the best vitamin C serums as far as absorption and layering before moisturizers and makeup primers. It’s like a quick brightening solution for my skin, which is why I love using it when I want to add quick simplicity to my routine.
Key Ingredients: Two forms of Vitamin C, Probiotic Extracts | Size: 1 fl. oz.
Best for Anti-Aging: StriVectin Multi-Action Super-C Retinol Brighten & Correct Vitamin C Serum
StriVectin has gained a fan following for its anti-aging formulas. Its Super-C Retinol Brighten & Correct Vitamin C Serum, contains — you guessed it — retinol, a powerhouse ingredient to help reverse and correct signs of aging.
Though I’m in my early 20s, I enjoy using a retinol-based product every now and then to protect my skin. I enjoyed the serum’s natural glisten. It wasn’t too shimmery either.

Key Ingredients: Vitamin C, Retinol | Size: 1 fluid ounce
Best for Quick Results: Kiehl’s Since 1851 Powerful-Strength 12.5% Vitamin C Serum
Kiehl’s Since 1851 has a Powerful-Strength Vitamin C Serum that lives up to its confident name. Despite it not being the most hydrating, it applies super smoothly and, in turn, helps minimize the appearance of pores and treat problem areas (fine lines, we’re looking at you) simultaneously.
It’s also infused with hyaluronic acid to give a bouncy skin effect. Because it’s void of fragrance and serves as a smoother for large pores, it’s one of the quickest-working serums I’ve tested.
Key Ingredients: 12.5% Vitamin C, Hyaluronic Acid, Vitamin E | Size: 1.7 fl. oz.
Best Skin Brightener: Mario Badescu Vitamin C Serum
Mario Badescu certainly knew what he was doing when his Vitamin C Serum was born. Wow is an understatement; I expected it to work well, but I was floored when I noticed how bright and glowy it left my skin.
It did, however, also leave it a bit shinier than I’d like, but if you want to see great brightening effects, this serum is your best bet. While it’s a bit thin in consistency and may be deemed runny by some, I find its absorption absolutely fantastic, allowing me to layer moisturizers beautifully after application.
Key Ingredients: Vitamin C, Collagen, Sodium Hyaluronate | Size: 1 fluid ounce
Best for Normal Skin: innisfree Green Tea Enzyme Vitamin C Brightening Serum
If your skin isn’t dry or oily, or doesn’t see acne all too often, the innisfree Green Tea Enzyme Vitamin C Brightening Serum is a state-of-the-art vitamin C serum that’s straightforward and soothing.
With green tea, your skin will become more soothed while glowy at the same time. Like the Farmacy 10% Waterless Vitamin C Serum, it contains tangerine peel extract which speaks to its light-as-air texture.
Plus, I noticed my skin became more even-toned right away. To help reduce oil and hydrate the skin, this brightener is great for anyone to use.
Key Ingredients: Vitamin C, Green Tea Enyzme | Size: 1 fluid ounce
An FAQ on Vitamin C Serums
What are vitamin C serum benefits?
You’ve heard of the ingredient but may be unclear about what does vitamin C serum actually do.
“Vitamin C is a potent antioxidant that prevents free radicles from breaking down collagen and elastin,” Dr. Patel explains. “You can tell if your serum is working after a week of using.”
She adds that your skin should be “smoother, softer and more glowy” and “maybe a few dark spots lighter, as if you have had an exfoliation” upon consistent use.
“Over months there should be a decrease in dark spots and a thickening of the skin,” she adds. “There may be fewer breakouts as well.”
What is L-ascorbic acid?
No, not all vitamin C serums are on the same level of efficacy. This is because vitamin C is labeled as an “unstable ingredient,” with serums containing L-ascorbic acid being the most active form of the vitamin.
“L ascorbic acid is the water-soluble form [of vitamin C],” Dr. Patel explains. “It’s most easily absorbed by the skin, unstable in sunlight and air (oxidizes) and is tricky in formulation; this results in the different qualities of vitamin C serums.”
Dr. Patel adds that esterified vitamin C is “much more stable in air and sunlight and not as irritating, but not as strong as L ascorbic acid.” That said, the difference in serum qualities “depends on concentration, formulation and packaging,” according to Dr. Patel.
How do I choose a vitamin C serum suited for my skin type?
Dr. Patel outlines different skin types and key ingredients to look for in a vitamin C serum:
- Dry or sensitive skin: Use a vitamin C serum with rose hip seed extract, sea buckhorn oil or vitamin E to help soothe the skin
- Oily skin: Use a non-water-based serum (opt for a creamier one instead) to help prevent the serum from evaporating
- Acne-prone skin: Look for retinol, AHAs and BHAs, along with anti-bacterial properties
- Mature skin: Look for ferulic acid, retinol, vitamin E and skin discoloration correctors
When to use vitamin C serum
For those curious about when to apply vitamin C, Dr. Pattel recommends doing so twice, daily, after cleansing the skin. Follow it up with a moisturizer, and don’t forget your sunscreen.
What percentage of vitamin C serum is the most effective?
Most skincare experts agree that the most effective percentage of vitamin C is between 10% to 20%. Products with a higher concentration can be irritating to the skin, and in very high doses can be toxic.
Is it okay to use vitamin C serum everyday?
It’s absolutely okay to use vitamin C every day. In fact, according to Dr. Patel, it can safely be used twice a day for the best results.
What we looked for while testing vitamin C serums
I’ve been testing 26 vitamin C serums for months on my dry to sensitive skin. Though — and confirmed by Dr. Patel — using a vitamin C-infused moisturizer is a less irritating formulation than a serum, I found 17 of the best serums that didn’t irritate my skin, highlighted pros and cons to help guide your decision (recommendations we would give IRL) and a list of some serums we tested that didn’t make the cut.
That said, my skin has never been brighter.
Aside from switching off from one vitamin C serum to the next, I didn’t use any new cleansers, moisturizers or face masks. I’ve used my two favorite products, as of late, with each test: Alpyn Beauty’s Creamy Bubbling Cleanser with Fruit Enzymes and AHAs and the brand’s PlantGenius Melt Moisturizer.
Here are some helpful things to note before reading our tried-and-true favorites:
Everyone has different skin types: As highlighted by Dr. Patel above, skincare ingredients depend on the skin type itself. This review is based on my skin (dry and sensitive) though, using Dr. Patel’s expertise as a compass, we grouped some of our favorites into other skin types.
You don’t have to splurge to confer benefits: The best vitamin C serum isn’t necessarily the most expensive, per Dr. Patel. “A lot of times the extra cost of a skincare product has to do with exorbitant or fancy packaging, with packaging not being a good indicator of the quality of the product inside.”
Talk to your doctor if you’re experiencing any serious issues: Though we consulted with a dermatologist to give an edit of the best vitamin C serums, everyone’s skin is different. Speak with your doctor if you have any underlying conditions or concerns before using a serum.
How we tested
After testing vitamin C serums for four years straight, here’s the criteria I kept in mind with each formula reviewed:
- Consistency: Some vitamin C serums are more lightweight than others, which may add to its appeal.
- Absorption: Going hand in hand with consistency, how quickly the brightening agent sinks into the skin is a key area to note.
- Price point: Typically, you get what you pay for, but each “dose” of vitamin C is different. L-ascorbic acid is typically more expensive because it’s the more natural form of the ingredient, though cruelty-free and thoughtfully formulated options can be as low as $14.
- Scent: For sensitive skin, specifically, a vitamin C serum with too strong of a scent is likely unwanted. This was noted for each serum tested.
