You’ve probably heard that you should be incorporating a vitamin C serum into your skin care routine, but aren’t quite sure why. Vitamin C is a powerful active ingredient that not only protects your body from environmental aggressors and boosts your immune system, but it can also have an incredibly beneficial impact on the health of your skin, including addressing common aging concerns (think dark spots, fine lines) and dullness.
Naturally, our skin changes as we get older. For instance, our skin reaches peak collagen production in our 20s, but slowly declines through the decades. That's why vitamin C is historically labeled by dermatologists as one of the best anti-aging ingredients we can use for our skin. By helping our skin build more collagen, the ingredient has proven results that all ages and skin types can benefit from.
Keep reading to discover the best vitamin C serums for anti-aging, brighter skin and more, according to dermatologists and Shop TODAY editors.

What does vitamin C do for your skin?
The benefit of using a powerful antioxidant like vitamin C is that it can help your skin build new collagen while preventing the loss of collagen and addressing dark spots and hyperpigmentation. "When applied topically, vitamin C reduces damage to our cells by neutralizing free radicals — which are highly reactive — and harmful molecules formed by exposure to environmental stressors (think pollution, UV light, etc.),” explains Dr. Corey L. Hartman, a board-certified dermatologist. Excessive exposure to free radicals can degrade collagen, which can lead to dull, saggy skin, according to the dermatologist.
Dr. Joshua Zeichner, Director of Clinical and Cosmetic Research in Dermatology at Mount Sinai Hospital in New York City, echoes this, adding that vitamin C is the best-studied antioxidant we have to treat the skin. In addition to the neutralization of free radicals, Zeichner says vitamin C serves two other main functions:
“It blocks the production of abnormal pigmentation to help lighten dark spots and even skin tone ... [And] it is an essential co-factor in the production of healthy collagen,” Zeichner explains.
What to consider in a vitamin C serum
When it comes to shopping for a top-rated vitamin C serum, our experts recommend the following features for consideration:
- Percentage: When on the hunt for a great vitamin C serum for your skin, you first want to look at the percentage of the ingredient in the product. “The sweet spot tends to be between 10 to 20% —anything below 10% won’t be as effective, and anything over 20% would be too irritating to the skin,” explains Hartman.
- Other ingredients that pair well: Vitamin C pairs well with other popular skin care ingredients. Hartman recommends looking for vitamin C products with complementary active ingredients to get the most bang for your buck. These include ferulic acid, caffeine, vitamin E and hyaluronic acid. “Vitamin C does not pair well with retinol or AHAs,” explains Hartman. “Most people will use a vitamin C serum in their morning routine, so leave the retinol and AHAs for your evening skin care routine.”
- Proper packaging: Pure vitamin C (aka L-ascorbic acid) is the least stable form of vitamin C and can lose its effectiveness if exposed to light and air. “A dark or tinted bottle is best to reduce light and airless delivery; a pump is ideal,” explains Hartman. “If you choose a vitamin C serum with a dropper delivery system, just make sure you tightly secure the bottle after use each day to prolong its effectiveness.”
The best vitamin C serums, according to dermatologists and editors
Best budget vitamin C serum:
While it doesn't always hurt to splurge on quality skin care, E.l.f.'s Bright Icon Vitamin C serum is proof that you get a whole lot of bang for your buck. According to editor Vivien Moon, the serum is a lightweight option that "layers beautifully with other products." Additionally, commerce editor and producer Julie Ricevuto attests to its non-greasy texture. Both editors complimented its size for its value and fast absorption, leading it to a perfect score in our previous Beauty Awards.
Best vitamin C serum for mature skin:
TruSkin’s vitamin C serum is an affordable vitamin C pick with a large following, including us (read our review here), as it was a recent winner in our 2025 Mature Beauty Awards.
“It’s on the higher end in terms of concentration, so I’d recommend using this serum if you know your skin can tolerate a higher concentration,” suggests Hartman. “It also has vitamin E and hyaluronic acid, which will help add moisture to the skin.” These are also helpful ingredients to address common signs of aging (dullness, improving suppleness), which, when paired with vitamin C, can boost their benefits.
Skin barrier-boosting:
This spa-grade serum is packed with a high concentration of vitamin C and tri-peptides, making it a powerhouse anti-aging product. But that’s not all: The formula is vegan, cruelty-free and non-comedogenic, too.
Zeichner likes the Bliss Bright Idea Vitamin C serum because it delivers a stabilized form of vitamin C, along with a peptide. “At the same time, it helps even skin tone and strengthens the skin itself,” he says.
Best vitamin C serum for sensitive skin:
The RoC Multi Correxion Revive + Glow Vitamin C serum is a great option for all skin types, but especially if you are sensitive.
“The ultra-gentle formula can be used even by people who are dry or who have previously experienced irritation with other vitamin C formulas,” says Zeichner. Plus, the addition of peptides helps boost luminosity and address dryness.
Best drugstore vitamin C serum:
Using 10% pure vitamin C, this drugstore, dermatologist-approved staple restores radiance to the skin in just one week. The brand also boasts that users can see visible anti-aging benefits at the two-week mark, too.
Hartman is a big fan of this product. “L'Oréal Revitalift Derm Intensive Vitamin C Serum is a nice option for first-time vitamin C users,” he explains. “At 10%, it will still be effective, but mild enough so that it does not cause irritation.”
"I used to use this and it's a great price point, really helps with texture and fades dark spots. It's thick so can actually be used as a moisturizer," says associate editor Shannon Garlin.
Results without irritation:
“Vitamin C was something I’ve avoided using for the past few years after a bad experience,” chimes associate editor Kamari Stewart-Jackson. “I’ve been using [this product] for two weeks, about twice a week, and I have experienced zero irritation and absolutely glowing skin!" even with a high potency of 15% vitamin C.
Best vitamin C serum for oily skin:
Both Hartman and Zeichner recommend this classic to their patients regularly. Hartman likes this serum because it leaves skin protected and radiant without irritation. “It combines a unique triple anti-aging ingredient complex with concentrated 10% pure vitamin C, salicylic acid and neurosensine [an active molecule known for soothing and anti-aging properties] for optimal effectiveness, while also being suitable for even the most sensitive skin," he explains.
Zeichner agrees, adding that the formulation gives an exfoliating effect. He adds, “This is a great option, especially if you have oily or acne-prone skin.”
Noticeable glow:
Though the brightening benefits take time, the luminosity after applying the Origins Ginzing Glow-Boosting Serum is definitely noticeable upon application. With ingredients to exfoliate, improve texture and smooth pores, this formula is a true hero for dull skin looking to boost radiance.
I [San Miguel] have experienced more texture due to winter dryness, and the serum improved my skin’s overall appearance after just one use. This makes it a great choice if you have normal to combination skin, but those with sensitive skin might experience some sensitivity due to the chemical exfoliant blend, per reviews.
If you're new to vitamin C:
The keyword to look out for in Summer Fridays CC Me Serum lies in its ingredient list: 3-O-Ethyl ascorbic acid, a modified and more stable version of pure vitamin C, according to research from Paula's Choice. The slower modification process makes it more tolerable, slower-reacting and easier to absorb compared to higher strengths of vitamin C. So if you're new to vitamin C or have experienced previous issues, this serum is worth adding to your routine.
"I get nervous to mix new skin care into my line-up, as I have sensitive, easily irritated skin, but I’m so glad I tried this serum," raves partnerships associate editor Erica Marrison. "It leaves my skin feeling both brighter and smoother."
Best vitamin C serum for dry skin:
“This serum includes powerful antioxidants, including vitamin C and niacinamide to brighten skin and help improve the appearance of dark spots,” explains Jeannette Graf, board-certified dermatologist and assistant clinical professor of dermatology.
The serum also contains polyglutamic acid, plant adaptogen extracts, among other hydrating ingredients, that left Stewart-Jackson "looking and feeling plumper after I apply it."
Great for acne scars:
“My favorite thing about this serum is how absorbent it is on the skin,” Garlin praises. “As soon as I apply it, my face immediately drinks it up, which allows me to apply moisturizer almost immediately ... I haven’t seen hyperpigmentation benefits yet, but I have been experiencing brighter and plumper skin. I look forward to using it more and more to see if the dark spots on my face fade in time.”
Best high potency vitamin C serum:
A higher concentration of vitamin C can easily provide noticeable results (though, like all products, you should do a test application first), just like the high potency of vitamin C in Saint Jane's Vitamin C Drops. With a 20% vitamin C blend, SEO writer Jannely Espinal noticed "my skin looks more hydrated and supple since using it" and calls it a quick fix if your skin needs an "instant glow."
Most gentle formula:
With just 5% vitamin C, this serum is one of the more gentle formulas out there. Aloe vera, zinc and hyaluronic acid in its line-up of ingredients help the product easily absorb without irritation. I [San Miguel] found the serum more hydrating compared to other vitamin Cs I've tried, so it has been a great addition to my morning routine, where I typically apply fewer products for better makeup application.
Best medical grade vitamin C serum:
You might've heard the term 'medical grade' skin care thrown around online, but it refers to products with high concentrations of clinically-proven ingredients, just like this multi-expert loved serum from SkinCeuticals.
“I love this serum because it is also a combination of ferulic acid and vitamin C, and this duo is amazing!” board-certified dermatologist Dr. Mina Amin previously told us. "These ingredients work to protect the skin barrier, increase firmness, and help promote a smooth and radiant complexion."
For a spa-like treatment:
One of the more luxury vitamin C serums I [San Miguel] I own, this brightening vitamin C serum from RéVive Skincare is like a spa treatment in a bottle. There's not a single ingredient in the formula that I don't love and that my skin type (dry), in particular, doesn't benefit from, including hyaluronic acid, snow mushroom and peptides, which naturally boost my skin's glow because of how hydrating they are.
Worth the splurge:
"I will say, this is super pricey, but I go through one bottle a year probably," claims social media editorial assistant Annie Shigo. "My skin feels so much better after using this, and I notice a visible difference in how awake I feel. I use it with a gua sha [tool] and love how smooth it is."
Frequently Asked Questions
According to Zeichner, vitamin C can be used across all skin types and is generally considered to be safe during pregnancy. That being said, it’s always a good idea to consult with your doctor or dermatologist before using any skin care products you’re unsure of.
“I typically recommend using a vitamin C serum in the morning,” explains Zeichner. “The morning is a time of protection and prevention of damage. I recommend layering vitamin C underneath your sunscreen every morning,” he adds.
Thankfully, vitamin C serums are actually a useful ingredient in treating acne and should not cause breakouts, according to Dr. Zeichner, who adds, “Vitamin C can be used every morning, even if you have acne.”
If you are worried about breaking out from a vitamin C serum, try to choose one that has a low percentage of vitamin C in the formula, or look for products with magnesium ascorbyl phosphate.
The good news: Yes, you can use vitamin C serums if you have sensitive skin.
“L-ascorbic acid is pure vitamin C, which is the most potent and refined version of vitamin C,” explains Hartman. “Skin care products with higher concentrations of L-ascorbic acid tend to be higher in price and may not be suitable for people with sensitive skin or for someone who has never tried vitamin C before,” he adds.
If you have sensitive skin, look for skin care products that use magnesium ascorbyl phosphate, a water-soluble and less potent version of vitamin C — meaning it will be less irritating on the skin.
“It’s also a good idea to do a patch test if you have sensitive skin or haven’t used vitamin C before,” suggests Hartman. “Put a small drop of your vitamin C serum on the skin on the underside of your wrist. Let it sit there for 24 hours, and if you do not experience any kind of irritation, slowly start to incorporate the product into your skin care routine,” he explains.
