Vitamin C has long been associated with feeling and looking better — I can’t be the only one who grew up being handed an orange at the first sign of a cold. It’s no different with skincare, where it has become the gold standard for brighter, more even-looking skin.
The latest luxury serums do far more than simply add glow, however. Today’s formulas are powered by exosomes, stabilised vitamin C complexes, NAD+, exfoliating acids and other magic ingredients designed to improve absorption, minimise irritation and maximise results. Whether you are tackling pigmentation, dullness, fine lines or a loss of firmness, your vitamin C serum may well be your new best friend.
What do dermatologists look for in vitamin C serums?
“Effectiveness, stability and skin compatibility,” Heather Wish, lead education manager at Paula’s Choice, says. “Proper formulary steps need to be taken for vitamin C to be effective and stable in skincare products, which is why not every vitamin C serum out there works.”
In general, well-formulated vitamin C serums use stabilised L-ascorbic acid at an appropriate pH, and may combine it with supporting antioxidants such as vitamin E and ferulic acid to help improve stability, brighten the appearance of skin and enhance antioxidant protection.

The best vitamin C serums for 2026
Dr Sebagh Exo C booster
While vitamin C has been the talk of the beauty world for quite some time, exosomes are this year’s buzzword. Once reserved for clinics like Dr Sebagh’s own, they are essentially tiny messengers that help transport actives directly into the skin. By incorporating plant-derived versions sourced from goji stem cells into this vitamin C serum, Dr Sebagh ensures that it does not simply sit on the skin’s surface but goes deeper. Exosomes also help stabilise the vitamin C, helping the formula to overcome oxidation and irritation. Ferulic acid and white mother of pearl help to create a luminous finish. £61.20, Dr Sebagh
Augustinus Bader serum
Augustinus Bader doesn’t add to its collection of science-backed skincare products very often. So when it does, you know it’s going to be something worth shouting about. The first vitamin C serum for the brand has been designed to help brighten the skin, even tone and add a layer of protection without causing irritation. It’s ideal for those looking to reduce dark spots or signs of dullness, while the inclusion of Bader’s signature complex Advanced TFC8, optimises the delivery and absorption of key actives. £290, Augustinus Bader
Paula’s Choice booster
After a bad night’s sleep, a cold or one too many martinis, you may well wake up and feel you need a shot of brightness as soon as possible. Paula’s Choice has a C15 super booster designed to do just that — in as little as 15 minutes, so the brand claims. This new and improved water-like formula targets dullness and uneven tone for a firmer-looking, more radiant appearance. Use it as it comes or mix a few drops into your favourite daily serum or moisturiser. £54, Paula’s Choice at Cult Beauty
Dr Barbara Sturm serum
What could be better than one form of vitamin C? How about three: one highly stable and oil-soluble, the second plant-based, the third synthetic and more stable in glucosidic form? This triple booster also includes zinc to help activate and transport the vitamin C mix into the skin more effectively, as well as aloe vera and hyaluronic acid for a hit of hydration. As with many of Sturm’s products, the Good C serum is anti-ageing — ideal for those trying to counteract the new formation of age spots and reduce the appearance of pigmentation. £125, Dr Barbara Sturm
Allies of Skin serum
Think of Allies of Skin’s daily advanced light reflecting serum as protective armour for your face. A combination of vitamin C and orange extract from citrus cells forms the basis of this shield against external aggressors such as pollution. Its unique balm-like quality may feel thick at first, but it instantly melts into the skin leaving a radiant finish enhanced by pure diamond powder. £93, Allies of Skin at Cult Beauty
Sunday Riley brightening serum
Sunday Riley’s CEO 15% vitamin C brightening serum is one of the brand’s most popular products, working to minimise the appearance of hyperpigmentation. As well as fortifying the skin barrier, it also helps reduce the visibility of pores and other skincare woes such as dullness, sensitivity and dehydration. £70, Sunday Riley at Cult Beauty
SkinCeuticals serum
SkinCeuticals is one of the most trusted anti-ageing skincare brands out there and for good reason. At the forefront of everything they do are visible and clinical results and this C E ferulic vitamin C serum is no different. With its impressive staying power (up to 72 hours after absorption) and both environmental and antioxidant protection, it is designed to help reduce the appearance of fine lines. It is expensive but a little goes a long way — you’ll only need four to five drops each morning. £169, SkinCeuticals at Look Fantastic
Omorovicza daily vitamin C
Alongside vitamin C to brighten and tone, Omorovicza’s serum also includes niacinamide (vitamin B3) to further boost the skin’s resilience, help reduce the appearance of enlarged pores and regulate the production of oil. The dry-skinned among us will be glad to see there’s also hyaluronic acid for a boost of hydration as well as the brand’s signature healing concentrate for extra nourishment. The result is a supple serum that isn’t greasy or oily. £115, Omorovicza
Westman Atelier concentrate
At £300 a bottle, you would hope that Westman Atelier, the make-up and skincare brand founded by renowned make-up artist Gucci Westman, would be a miracle worker. We can’t quite claim that, but we can tell you it’s a single-ingredient vitamin C concentrate. And while that might sound like you’re getting less for your money, the Suprême C vitamin C concentrate actually eliminates the common drawbacks of traditional serums like oxidation, tackiness and irritation. It relies on a Japanese derivative of vitamin C known for its brightening and firming yet gentle results. £300, Westman Atelier at Cult Beauty
Dr. Dennis Gross serum
Dr Dennis Gross’s Vitamin C + Lactic 15% Vitamin C Firm & Bright serum contains a combination of lactic acid and L-ascorbic acid to help reduce the visible signs of ageing frequently caused by sun exposure. Lactic acid, which is an AHA, helps speed up cell turnover and sweep away dead skin, allowing the vitamin C to penetrate deeper. The addition of liquorice root also combats hyperpigmentation while vitamin E (tocopherol) and hyaluronic acid help prevent dryness. £87, Dr Dennis Gross at Space NK
Dr Sam’s serum
NAD+ (nicotinamide adenine dinucleotide) is a vital coenzyme found in every living cell, often referred to as the skin’s “cellular battery”. It helps support the appearance of skin vitality, targeting environmental stressors and promoting a brighter complexion. responsible for fuelling cellular energy, helping to repair DNA and controlling inflammation. Like a phone battery, however, our natural cellular NAD+ levels drop by about 50 per cent by age 40. Here, the Flawless Vitamin C NAD+ serum pairs a potent 15% vitamin C complex with breakthrough sunflower shoot extract to boost the skin’s internal NAD+ levels. The result is a powerful daytime serum that helps combat environmental stressors such as UV and free radicals to produce a brighter complexion. £64, Dr Sam’s
Murad serum
Not all vitamin Cs are created equal. Many lack stability and bioavailability (how easily the skin can use an ingredient) that hinder their potency and power. Murad’s Vita-C Glycolic Brightening serum answers that common problem. The glycolic acid helps to accelerate the cell turnover process by resurfacing the upper layers of the skin and creating a visibly smoother appearance. This might sound scary but it isn’t — there’s no redness or peeling, just brightness and radiance. £88, Murad
Rodial booster drops
With so many serums to add to your routine, you can leave the bathroom feeling as if you’re wearing layers upon layers of different creams, slipping and sliding all over your face. Thankfully, Rodial Vit C booster drops are neither heavy nor sticky nor harsh. The thin, almost water-like texture absorbs almost instantly into the skin and the pipette dispenser makes it easy to add a drop straight to the face or via a moisturiser. £62, Rodial
Sarah Chapman serum
British skincare expert Sarah Chapman is one of London’s most sought-after facialists — unsurprisingly, her skincare line Skinesis is also a bestseller. Her Vitamin C power 2 face serum is special because it uses a unique delivery technology that pairs oil-soluble and water-soluble forms of vitamin C to ensure deep, targeted absorption. £115, Sarah Chapman at Space NK
Frequently asked questions
Answered by Heather Wish, lead education manager at Paula’s Choice
What are the benefits of vitamin C serums?
“Vitamin C is a skincare superhero. When applied topically, it can significantly improve persistent skin concerns such as dark spots, dull tone and the loss of firmness that result from sun damage and ageing. As a potent antioxidant, it combats the daily onslaught of free radical damage, shielding our skin from harm. In addition, it’s a master at reducing inflammation and enhancing the skin’s resilience against the ravaging effects of UV light.
“Interestingly when we’re young, our skin has an abundant supply of vitamin C, offering natural protection. However, over time with sun exposure and ageing, this vital nutrient dwindles. By incorporating vitamin C into your skincare regimen, you’re essentially replenishing what years of sun and age have taken away.”
How to apply vitamin C serums
“Vitamin C combines well with other skincare ingredients (including retinol, niacinamide and chemical exfoliants) and works well both day and night; it’s really up to you when to add it. Just make sure you always follow up with sunscreen; otherwise, the UV rays will undo what the vitamin C has corrected. Keep in mind that it can take a while to fade more stubborn discolorations. Be consistent and give it six to eight weeks of daily application.”
How do you store vitamin C serums?
“Vitamin C is extremely sensitive to air and light. For the best results, your serum or moisturiser needs to be in an opaque, air-restrictive bottle or pump container to help ensure the ingredients remain stable. A vitamin C cream that comes in a jar or clear packaging won’t remain effective for long.”
