The 12 Best Vitamin C Serums + Benefits & Application Tips

This is my personal favorite vitamin C serum—the one I keep going back to and have recommended countless times. It contains four different kinds of vitamin C (l-ascorbic acid, l-ascorbyl palmitate, tetrahexyldecyl ascorbate, magnesium ascorbyl phosphate) that help provide a wide range of benefits. Then it's combined with vitamin E and ferulic acid, which help bolster the antioxidant's collagen-producing abilities. It's a genius formula that seriously delivers.

What users say: 

Not only is this my personal favorite, but it’s a bestseller at Credo and has been highlighted by the likes of New York magazine, Harper’s Bazaar, and more. Users agree that if you can tolerate the smell—it’s well worth it: “It’s my favorite Vitamin C serum. I find it really does improve my complexion and make it brighter.”

This has a bouquet of antioxidants—including 12% ascorbyl glucoside—as well as kakadu plum, acerola cherry, orange peel, lemon peel, and noni fruit. Translation? This is like a morning superfruit smoothie for your skin. But it doesn't stop there. It has the humectant sodium hyaluronate to help skin hold on to water and olive leaf extract to soothe irritation. 

What users say: 

Yet another vitamin C serum I keep in regular rotation, I’ve made my way through at least two of these bottles. It’s a solid formula that folks who prioritize organic ingredients will love—one user notes they're a repeat user too: “Third time I bought this vitamin c serum—certainly worth a repeat.”

If your main goal is brightening dullness, reach for this powerful option that comes with a potent dose of 15% stable Ethyl ascorbic acid as well as 5% polyhydroxy acids. PHAs (sometimes called gluconolactone) are an innovative alternative to AHAs that helps even skin tone via chemical exfoliation and are super gentle. There's also hyaluronic acid to help hydrate and plump skin for a dewy affect.

What users say: 

The illuminating serum gives an instant vibrant lift upon application, but users love it for the long-term results too: “Helps even out and brighten skin. I've gotten so many comments from people telling me I'm glowing since I started using it.”

OK this isn't a serum, however, if you're looking for an oil version vitamin C this is your best bet. It uses lipid-soluble vitamin C called Tetrahexyldecyl ascorbate, and it's blended with the brand's signature squalane. An application tip: This should be used to top your skin care routine as it's thicker, and other items won't be able to penetrate the skin as easily. Consider this your option if you have extra-dry skin and need to trap in moisturizer—however, it will likely be too thick for those with easily clogged skin.  

What users say: 

This award-winning oil has racked in over 2K reviews on their site, including 1.7K 5-star comments like this one: “I wake up to see my skin looking better than ever before. Bought it as a present to myself on my 62nd birthday. I wish I had it 20 years ago.”

A more potent option, this combines 20% Bis-Glyceryl Ascorbate and a 10% AHA blend. This will provide serious brightening, exfoliating, and smoothing properties. Consider this your ideal formula if you have breakouts, acne marks, texture concerns, or wrinkles. However, if you have sensitive skin—this can be irritating, so I recommend avoiding it.  

What users say: 

As someone with sensitive skin, I can’t use this regularly—however, I count it as a staple overnight treatment when I need to wake up glowing. As for folks with a bit more durable skin than I, one user says: “Thanks to Tatcha, I cried happy tears this morning because I woke up to 100% clear skin for the first time since I was 13 years old (I am 29 now). I have used this product morning and night for the past 1.5 months.”

For those with sensitive skin, ingredient lists can be a landmine of irritation. There are a few ones that standout as common triggers, such as retinol and AHAs. However, did you know that many types of vitamin C can be hard to tolerate, too? This option uses a lower concentration of 5% vitamin C, alongside super calming and hydrating ingredients like hyaluronic acid, aloe vera, and zinc.  

What users say: 

Lots of folks struggle with finding a vitamin C product that doesn’t make their skin go haywire. But this hydrating blend has proven to be the right fit for many folks: “This is one of the first Vitamin C’s I can use that doesn’t leave me red and irritated. Lightly hydrating also.”

This award-winning serum has rave reviews across the internet, making it a natural cult favorite. We know why: This smart formulation has a solid mix of actives to bring your skin serious all-over benefits. There's the vitamin C (as sodium ascorbyl phosphate), hydrating glycerin, stabilizing vitamin E, soothing aloe, and plumping hyaluronic acid. 

What users say: 

The hard truth is that vitamin C serums are an expensive category—and one in which you get what you pay for. This is because vitamin C is a hard active to formulate with, and requires high-quality ingredients alongside it. However, one user notes that this is a standout amongst other more expensive formulas: “I’m sure I’ve spent a small fortune on my face over the last 15-20 years and between all the random OTC products, dermatologist visits and prescriptions, this is one I am very pleased with so far!”

We love the plant actives and botanicals in this blend. Of course there's the vitamin C, but there's also rosehip seed oil (high in vitamin C in its own right), aspen bark (a natural source of salicylic acid to help deal with oil production and acne), aloe (for soothing and hydrating; it can also fade dark spots), and rose (for balancing tone and texture).  

What users say:

A lightweight formula that won’t clog pores and will help treat breakouts with botanical extracts. What more could you ask for? Users agree: “It makes my skin clear and bright. Keeps my completion smooth too.” Another says: “For about 25 years I felt like I needed to hide my skin behind tints or concealer…now I let it glow and let it go!”

The base is a 10% blend of two forms of vitamin C that help deal with dark spots and dullness. Additionally, the serum gets extra antioxidants from turmeric and camu camu extracts. We particularly love turmeric, as it's known as a famous anti-inflammatory and can tame angry skin.

What users say:

With almost 9K reviews and a near perfect score of 4.9, this serum has inspired a loyal fan base. One writes: “The application is like silk and absorbs quickly into my skin. I am 78 and I get compliments on my skin all the time. People always think I am much younger.”

This ultra-moisturizing facial serum feeds skin antioxidants from vitamin C, E, and green tea, while conditioning skin with jojoba oil, shea butter, and sea buckthorn oils. Put that all together and you've got seriously hydrated, glowing, happy skin. 

What users say: 

What makes this so appealing for people with dry skin? The texture, as one user described it as “halfway between a serum and an oil,” explaining that “there's usually unabsorbed product on my skin, but I don't mind the extra hydration” and “spreading this serum across my skin feels so luxurious.”

This starts as a powder blend of vitamin C and ferulic acid—just sprinkle a bit into your serum of choice and you'll bring loads of antioxidant benefits into the base formula. Basically you can make any serum a powerhouse vitamin C option with this powder!

What users say:

This powder is an option I always have on hand—who doesn’t want semi-DIY vitamin C serum they can create in a pinch? And because it’s powder, it’s travel-friendly! Other users love that they can mix-and-match as well: “I like this vitamin c because it feels like I’m a chemist and it’s good to mix with my serums.”

A perfect option for your morning vitamin C serum, this combines the vitamin with caffeine (caffeine is a great option for skin as it encourages circulation to the skin) from superleafs yerba mate and guayusa to immediately brighten, visibly reduce morning puffiness, and hydrate. 

What users say:

Just like people cherish their morning cup of coffee, users cherish their morning dose of this serum: “I’ve used this product for a couple years now and have yet to find anything that compares. I love the glow that it gives my skin in the mornings.”
