The best vitamin C serums will feel comfortable to wear while slowly brightening the skin over time to fade away dark spots and leave skin overall less dull and more glowy.
Vitamin C is one of the most essential a building blocks for healthy skin and a good skincare routine, as it has been scientifically proven to improve signs of sun damage. Whether you're choosing between sunscreen vs sunblock, look to vitamin C when working out how to fade dark spots and even out skin tone—whilst protecting against pollution and free radicals too.
From vitamin C serums that received tonnes of great reviews to ones that have whipped up a cult frenzy, our team of expert contributing beauty editors put several serums to the test to find the very best.

Naturally, there are some that have risen to the top of our best list, so honorable mentions go to Medik8's Super C30 because it combines efficacy with an accessible price point.

Our pick of vitamin C serums will help you see improvements with everything from pigmentation, dullness and discoloration to how to get rid of dark circles, uneven texture and fine lines.
How we tested the best vitamin C serums
When testing vitamin C, they were each used for around a week, taking into account the following factors.
- Texture—thinner formulas tend to work best for vitamin C serums, as they soak into the skin more easily
- Type and strength of vitamin C used—a higher strength will obviously yield faster and more obvious results, but a lower strength is best for those starting out or those with more sensitive skin
- Cost—there are various different price points for vitamin C and while some of the best ones can be quite expensive, there are also really effective options on the lower end of the price spectrum
- Packaging—is it air-tight and does it use dark packaging in order to keep the formula stable for as long as possible?
- How it feels on skin—while it can sting a little at first, it should be generally comfortable to wear, especially after a couple of uses
It was important to take into account numerous price points—as vitamin C formulas can range hugely in price—alongside the packaging. And we also spoke to experts in order to find out what we should be looking for in a vitamin C serum and what different types of vitamin C are best to look out for and why. It's all important to consider what vitamin C serums will work with the best foundations for sensitive skin, and all skin types.
My skin can be sensitive to some ingredients but it’s generally quite hardy, is a bit blemish-prone and falls on the slightly oily side.
For me, vitamin C serums come in many different types and textures, and finding out suitable for your own skin is trial and error. Personally, I like something lightweight that doesn't feel overly oily—in fact, the more water-like, the better—and that will absorb into skin easily without leaving a trace.

I found that this lightweight, dry oil sinks into the skin without leaving it feeling greasy or slippery. A couple of drops smoothed all over your skin is all you need, and thanks to its quick absorption, it works perfectly as the first step after cleansing in your AM or PM routines.
The formula contains 30% ethylated L-ascorbic acid, meaning it’s both potent and incredibly stable. Plus, it’s free of artificial fragrance yet has a refreshing, zesty scent to it which comes from the addition of grapefruit extract (which also acts as an additional, natural antioxidant). It’s oil-based so not only will it help to brighten and protect skin but it’s also incredibly hydrating. Skin looks brighter with a couple of weeks’ consistent use.

2. Dr Barbara Sturm The Good C Vitamin C Serum

This serum takes a novel approach to vitamin C and is packed with proven hydrators. Rather than flood skin with a high concentration of vitamin C, skincare expert and aesthetician Dr. Barbara Sturm believes that 5% is the sweet spot to brighten, improve the look of hyperpigmentation and boost collagen production—all without potentially impairing the protective skin barrier and leading to inflammation. Not to mention this powerhouse contains three different forms of vitamin C, including Kakadu Plum—a potent fruit source of plant-based vitamin C—and zinc, which aids with absorption into the skin.
Unlike most vitamin C formulas that are a deep orange shade, this is white and feels more like a watery cream. And as it's a completely stable form of vitamin C, there’s no danger of the liquid turning an unsightly brown color due to oxidation. Better still, I found that it sunk quickly into my skin without leaving a sticky residue—although the brand does recommend waiting for five minutes before applying moisturizer over the top to really let it works its magic.
3. Tatcha Violet-C Brightening Serum

J Beauty is all about balance and this formula is a testament to that. Alongside a vitamin C derivative that helps to minimize attack on your collagen and DNA from free radicals, there’s Japanese Beautyberry, another rich source of antioxidants that helps to stabilize vitamin C. AHAs, derived largely from citrus fruits, have also been added at a gentle yet effective 10% to lift away uneven, dull skin. These are given an additional boost by Japanese Angelica Root, which helps to diffuse the look of excess melanin. Given the built-in AHAs, you won’t need to use any chemical or mechanical exfoliators while using this product.
Those with more sensitive skin may want to slowly introduce the serum into their routine, starting with use every other night to allow the skin to acclimate. I found that the lack of mineral oil means this serum feels lightweight, won’t clog pores, and plays nicely under makeup. It’s an all-rounder when it comes to a more translucent, youthful glow.

For those that prefer natural skincare options, this is best for you as it is free from parabens, synthetic fragrance, dyes, petrochemicals, SLS, or other additives. The antioxidant ingredients (ferulic acid, vitamin C and vitamin E) are the stars of this serum super lightweight serum.
When it comes to application, I found that the jelly-like texture soaked into my skin immediately and didn't leave the skin feeling tacky. The fact that it’s water-based is good news for oily skin types, as it’s less likely to clog pores, and is undeniably a draw in summer when we’re lightening up our skincare layers.
It’s also a beneficial serum for oily skin types and for those who normally find their skin becomes riled after using vitamin C.

In just a few weeks into using the SkinCeuticals CE Ferulic serum, my skin was noticeably much more glowy than normal. Unlike other similar serums which tend to be on the slightly more viscous side, this one is like water—so I found that it was best to press into my face from the palms of your hands, rather than dripping straight onto the skin. It absorbs quickly and doesn’t leave skin feeling sticky or tacky—instead, it’s the perfect base to apply your best sunscreen for face on top of.
It’s formulated with ferulic acid, a plant-based antioxidant that helps protect skin against free radicals and other environmental damage, as well as vitamin E which offers additional protection. It left our tester's skin looking and feeling plump, hydrated, and glowing.
"Out of the many vitamin C serums that I've tried in my career, this is no doubt my number one pick," adds My Imperfect Life's deputy editor and in-house beauty expert, Aleesha Badkar. "The first time I used it I was genuinely shocked by the results that I saw, as not only did it fade any signs of pigmentation on my skin in just a couple of weeks, but it also left my complexion with a plump, healthy appearance and a natural glow that I honestly only thought possible from cosmetic procedures".

6. The Ordinary Ascorbyl Glucoside Solution 12%
Specifications

Reasons to avoid
The Ordinary has gained cult status by democratizing the skincare industry and as the go-to skincare brand for ingredients-led and results-driven products—its aim is to simplify the overcrowded, often-confusing world of skincare and this serum is yet another great product that does exactly what it says on the bottle.
Formulated with ascorbyl glucoside, a type of water-soluble vitamin C that has a longer shelf left in terms of stability than some, it’s a true no-frills serum that glides onto the skin. I found that the non-oily texture absorbs easily but—contrary to what the brand describes—can be a bit sticky and can lead to pilling if too much is applied. It can be mixed with other antioxidants, such as resveratrol or ferulic acid, for a full 360 approach—but to get better results with this you need to do your research.

La Roche-Posay is the go-to brand for those with sensitive skin so products are developed with that in mind, and this serum is no different. Formulated with 10% vitamin C, it’s the lowest strength of the lot but it still works to even and smooth skin, while the added salicylic acid gently sloughs away surface layers of skin and hyaluronic acid deeply hydrates, leaving it plump and radiant.
It’s also infused with La Roche-Posay’s iconic thermal spring water which promises to deliver soothing, barrier-repairing benefits. I found that its texture sits somewhere between water and a lightweight gel meaning that it absorbs really easily—and it left my skin looking healthy.

Four individual vials with two compartments—one holds the ready-to-mix pure vitamin C powder and the other houses the serum. Peel the foil away at the base, click and press the powder into the serum, give it a shake and it’s ready to use, either alone or dispense a couple of drops into your favorite daily moisturizer in order to give it a boost.
The so-called ‘stay fresh’ packaging is designed to keep the vitamin C powder as fresh and as active as possible, therefore meaning maximum results and impressive efficacy. Each vial is designed to last seven days and is available to buy in boxes of four—to last a month—or one, to see you through a week.

Glycolic acid slews away dead skin cells, which clears the way for vitamin C to really get to work thus supercharging the effects. This serum, from Murad, is perfect for targeted treatment. This formula works with most skin types from normal to dry and combination.
Another favorite of deputy editor Aleesha, she says: "My first plus with this one was the packaging, as the separate compartments meant that it lasted a bit longer than other vitamin C serums due to preventing oxidation. The texture is a little thicker than I usually like in a vitamin C serum though, but it does still absorb quite well and leave the skin feeling and looking fresh and bright.
"I have relatively robust skin, but I did find that I sometimes felt a slight sting or tingle when using this—nothing too uncomfortable or that couldn't be remedied with a quenching hyaluronic acid serum or calming moisturizer for dry skin—but it's probably one for sensitive skin types to avoid and that would best for experienced vitamin C users."

Suitable for all skin types, you only need a few drops as it’s not very viscous. The texture is quite loose and can be compared to that of the Skin Ceuticals C E Ferulic. That being said, it soaks into the skin like a dream.
To activate this product, you have a separate sachet of vitamin C powder which you carefully add to the bottle. You then need to shake it for 30 seconds to ensure the product is completely mixed through and leave for 2 minutes before application. But, you only have to do this once.
I found that my skin was definitely noticeably brighter after the first use, and this continued with solid use, both in the morning—followed by SPF, of course—and at night.
They say the product is at its most efficacious up to one month after using, so in terms of price, it is definitely at the top bracket of products. But even so, if you're looking for an instant boost, this is the one to try. It does have a tendency to sell out quite quickly, so definitely one to add to your wishlist so that you can snap it up ASAP.
How to choose the best vitamin C serum for you
Whilst we can acknowledge that vitamin C is undoubtedly an incredible addition to any skincare routine—the vitamin C serum benefits are seriously impressive—it's worth noting that not all products were made equal. If you're wondering how to fade dark spots, vitamin C can do this and it also works to help even out skin tone while improving the appearance of post-inflammatory hyperpigmentation. It can also help to protect against pollution and free radicals, both of which can cause premature aging.
Despite being considered one of the best antioxidants by almost all dermatologists and skin experts, vitamin C is notoriously difficult to formulate because it’s extremely unstable in water-based products. That means it’s always best to choose a vitamin C serum that’s oil-based to ensure maximum efficacy for the longest possible time.
Vitamin C serums tend to come in different strengths and can range anywhere from 2% through to 20 or 30%—the optimum is around 10-20%. The higher the number, the more potent the product will be. However, there’s no need to choose something higher for the sake of it. If you have sensitive skin, it's always advisable to start lower and gradually work your way up. That way, your skin is able to adapt and is less likely to react.
"Formulation matters, particularly with vitamin C as the active ingredient is relatively unstable and in time, the vitamin C becomes less “active”," advises dermatologist Dr Bernard Ho. "I would suggest looking at the manufacturers or product details as it will tell you how long they expect your vitamin C product to last and when to use it up by."
There are also various types of vitamin C, and while they will all have the same end result, some are easier for brands to formulate with than others. The most popular and most common form of vitamin C is L-ascorbic acid—it’s the most potent but it’s also the most unstable. Other forms include tetrahexyldecyl ascorbate, which is the most gentle and least likely to cause irritation; and ascorbyl glucoside, which is a stable form of vitamin C that’s been combined with glucose, making it more tolerable in sensitive skin.
Can you use vitamin C everyday?
As for how to use vitamin C serum, it's fine for daily use, but best not to use with retinol—so we'd recommend alternating between the two or using them at different times of day.
"I would suggest not layering vitamin C with retinol, as it can cause irritation when used at the same time," explains Dr Ho . "I would advise using any product (providing it's not causing irritation or unwanted side effects) for 4-6 weeks before deciding if it has done anything to your skin. I would suggest looking for vitamin C product that combines other hydrating ingredients such as glycerin and hyaluronic acid."
And if you're wondering whether you should use your vitamin C serum morning or night, it's actually suitable to use both morning and night—or one or the other, depending on your skin’s needs.
