Medik8 C-tetra luxeBest OverallSize 30mlScented YesThe instructions for this serum call for six drops to be massaged over the face and neck, but our tester found around three or four actually worked perfectly and, of course, made the product last a bit longer too. When applying, the soft citrusy smell is a great morning wake-up scent, while the silky feel is instantly luxurious and very easy to apply thanks to a precise small brand revolves around a CSA strategy – vitamin C, sunscreen by day and vitamin A by night – emphasising just how core an element vitamin C plays within the brand ethos and skincare in general. The catchily named, tetrahexyldecyl ascorbate THD is the vitamin C of choice for this serum, meaning it’s gentler on the skin, easier to store and more stable in squalane, vitamin E, F, maracuja oil and red ginseng are also included for a deeply moisturising treatment helping to protect the skin barrier, stimulate collagen production and nourish cells. For anyone who wants to strip their skincare routine back even further, the brand’s two-in-one moisturiser vitamin C cream was also loved by our reading...RoC multi correxion revive and glow capsulesBest Vitamin C loversSize 30 capsulesScented N/AWe’ve emphasised how difficult it can be to store certain vitamin C serums already and even had a real-life example of just how easy they can be to spoil with Bondi Sands. So, coming in capsule form, this RoC option is one of our favourites for fuss-free, easy use whether at home or on the 20 per cent ascorbic acid, it’s on the higher end of concentration and luckily the capsule has already dictated the exact amount needed, meaning there’s no need to worry about overdoing it and causing irritation. Although, in saying that, beginners would be better suited to lower levels before moving on to is the main ingredient, an intense moisturising ingredient known to help with conditions such as eczema, so it is intensely hydrating too. While rubus idaeus leaf cell cultures hydrate and work to reduce signs of ageing, polygonum aviculare extract helps protect against UV and infrared rays, and terminalia ferdinandiana soothes inflammation. Fine lines were notably reduced, skin felt hydrated, and it instantly absorbed with no greasy residue. For well-versed vitamin C users looking for a change, this is one to go reading...Revolution skincare vitamin C glow serumBest Budget buySize 30mlScented YesRevolution is quickly becoming one of the most popular go-to’s for bargain beauty buys, and we can see why. At just £10, this per cent vitamin C serum is a great option for anyone who has already started using it and is looking to take one step up without breaking the acid is the type of vitamin C used, with water, glycerin, grape seed oil and orange peel oil all adding hydrating, skin-nourishing benefits to the formula. The scent isn’t too strong and reminded us more of a fake tan smell than punchy citrus, but our self-tan-loving tester didn’t mind this at all. Our tester’s skin texture did appear smoother and the silky, lightweight formula did feel quite luxurious when applied to the skin. And, even better, for those looking for a smaller concentration, there is also a three per cent option reading...Omorovicza daily vitamin CBest Luxury loversSize 30mlScented YesLuxury skincare lovers rejoice, as of course we’ve included Omorovicza in this round-up, how could we not? Firstly, we have to note that it is quite the expense. The Hungarian brand prides itself on its ingredients, history, results and science-led design, so our tester was more than excited to give this vitamin C serum a sodium ascorbyl phosphate as the form of vitamin C – the same structure as used in the Aesop version – it’s again very stable with no chance of oxidisation, a huge relief when spending over £100. The main ingredient is water – which seems like quite a shame when considering the price – but it’s not just any water, it’s Hungarian thermal water, which is said to have impressive healing properties and a high mineral concentration. Niacinamide, nasturtium officinale flower/leaf extract, radish root ferment filtrate and actinidia arguta fruit extract work to nourish and protect the skin while keeping it clear and free from acne-inducing packed with skin-boosting ingredients and with a boujee bottle to match, we can see where the price point comes in. But, if you do have the money to spend then definitely give it a go – one drop was enough to cover our entire face so it’s sure to last you a very long reading...Olay vitamin C + AHA 24 day gel serum for bright and even toneBest Dark spotsSize 40mlScented YesOlay has been backing its vitamin C range for a while now with Amelia Dimoldenberg, aka host of Chicken Shop Date, as the face of it. But, it takes more than a celeb face to sway us here at IndyBest so we put this product through its paces, just like the others, to see if it really is worth parting the cash first thing to note is the scent, a fresh citrus banana whiff that reminded us of that yellow medicine as kids – both a good and a bad thing. The pipette is very easy to use, and only a few drops cover the whole face. Do note this product is cloudy, so don’t be thinking it has spoiled if the scent is still was slightly sticky compared to other options but did absorb into the skin quickly with long-lasting moisture. It’s the 3-O-ethyl ascorbic acid that is used here along with glycerin, niacinamide, dimethicone and lactic acid for a moisturising yet exfoliating treatment that can be used both morning and night, making it a great option for anyone looking to reduce dark spots and brighten reading...Bondi Sands gold’n hour vitamin C serumBest For beginnersSize 30mlScented NoWorking as a sun protection agent when combined with SPF, it’s unsurprising that sun expert Bondi Sands has brought out its own vitamin C serum. With 10 per cent ascorbic acid and a touch of vitamin C-filled kakadu plum fruit extract, this is a great option for beginners. Easy to use, simply drop three to four drops into the palms and massage into the skin post-cleansing and before moisturising and it’s an extra skincare step that won’t take more than a few root extract has been added to help reduce inflammation along with microcitrus Australasica fruit extract for exfoliation, giving it extra skin-enhancing properties. But, being an active form of vitamin C, it did spoil, turn bright yellow and smell rancid after around three weeks of being open – which could’ve been user error of not tightening the lid enough, or could be a downfall of the unstable ascorbic acid reading...Trinny London boost upBest High concentrationSize 30mlScented YesWe know we’ve already said that 20 per cent is really the maximum recommended concentration of vitamin C when going by general consensus, but Trinny has blown everyone out of the water with this 30 per cent concentrate. Once again, 3-O-ethyl ascorbic acid is the vitamin C of choice and the main ingredient in this serum, meaning it is incredibly strong. But, even after a couple of weeks of use, we experienced no irritation, sensitivity or burning. Perhaps this could be due to the other potent and nourishing ingredients, jojoba oil, olive oil, plankton extract, lemon peel ferment, lactococcus ferment and meadowfoam seed with the majority of the Trinny London range, this serum has been created with older skin in mind, so anyone in that category is sure to love this product. But, if new to vitamin C, be sure to train your skin for a couple of months beforehand with one or two of the lower concentrate options in this round-up first, just in skin appeared brighter, smoother and more even in tone after continued use which is sure to increase as time goes on. And, best of all, it’s also refillable meaning less reading...Aesop lucent facial concentrateBest All-rounderSize 60mlScented YesNot strictly just a vitamin C serum, but marketed as such, the Aesop lucent facial concentrate is the brand’s take on a classic vitamin C product. In the classic aesthetic Aesop packaging, we loved having this sit pride of place on our bathroom shelf and the pipette was easy to use and large enough that just two drops covered most of the face and neck with the silky, instantly absorbing ascorbyl phosphate is the vitamin C of choice here and being the most stable option it won’t oxidise, so there’s much less worry about spending this much money on a product that could quickly go off. Niacinamide, hydrogenated castor oil, boswellia carterii oil, fusanus spicatus wood oil and rosa damascena flower oil closely follow in the ingredient list providing a blend of moisturising, conditioning and nourishing ingredients that really are worth their weight in any skin type will soak this up and look radiant with a glowy yet semi-matte finish our tester fell in love reading...Catrice glow vit C power shots pack of 5Best Something differentSize NoUnlike any of the other serums, these Catrice vitamin C shots come individually portioned in a pack of five small glass tubes. Unscented and non-pigmented, each one contains of serum, which actually is quite a lot when viewed in the case. Annoyingly it needs to be used at once for an intense treatment and we actually ended up using the excess on scars and marks across the body type of vitamin C included here is the 3-O-ethyl ascorbic acid – a stable, water and oil-soluble derivative of ascorbic acid that offers all of the benefits without the unstable nature. At 12 per cent, it’s a good level for those who already use a gentle vitamin C serum and beginners are encouraged to use it every two or three days. For anyone using it every day the price is sure to rack up to be higher than that of most other serums, so maybe keep this one for a spa-like treat every now and reading...Ole Henriksen banana bright vitamin C serumBest BrighteningSize 30mlScented YesFamous for its banana bright eye crème, Ole Henriksen is a beauty lover’s go-to for brighter eyes. And the main ingredient? Vitamin C. What many people don’t know is that the brand also has a pretty impressive vitamin C serum for the whole face, and that’s what we put to the 15 per cent vitamin C – stemming from 3-O-ethyl ascorbic acid – and five per cent polyhydroxy acids PHA’s stemming from fruit acids, this serum works to instantly brighten and boost skin for a fresh-faced glow. Hyaluronic acid is included for added moisture while banana powder-inspired pigments nourish the skin from the tester fell in love with the fresh citrusy scent and the silky feel of the product immediately. Although it feels a little heavy on the skin at first, it absorbs within around ten seconds with a semi-matte finish while feeling hydrating for hours afterwards. Do note, unlike most other options in this round-up that are best applied in the morning, due to the level of PHA exfoliants, this one is best to be used at night to avoid instant sun reading...Trilogy vitamin C booster treatmentBest Quick fixSize NoThe majority of at-home skincare products don’t work wonders overnight. And vitamin C serums are no different, with a usual recommended usage of between six and eight weeks before results start to become visible. So, this two-week at-home treatment promising to improve skin tone, brightness and glow was something we just had to in many ways from all of the other products in this round-up, this serum includes six per cent ascorbic acid in powder form – reducing its risk of spoiling – which can then be popped into a hyaluronic acid, aloe vera extract concentrate for a fresh, potent serum that lasts for a maximum of four weeks. Alongside the vitamin C, hyaluronic acid and aloe vera is daisy flower extract, orange peel oil and rosehip seed oil which create a cocktail of nourishing, antioxidant properties that hydrate and plump the the two weeks, our skin appeared brighter and more luminous, but the daisy flower extract is also known to lighten skin too – so be mindful of this if lightening is something you’d rather not opt for. Although, if you’re after a quick fix and almost instant results, this may be the one for reading...Simple booster serum 10% vitamin C+E+FBest Everyday useComing in at under £10, this Simple serum really is a great budget buy for an everyday essential. Incorporating vitamins C, E and F, it’s a bit of an all-rounder. But, if you’re now wondering why some of the other options in the round-up are considerably more expensive, let’s take a closer to be ten per cent concentration of all of those vitamins, this product actually breaks down to include two per cent vitamin C, one per cent vitamin E and seven per cent vitamin F. So, while it still will provide some goodness to your skin, you’re unlikely to see many of the key vitamin C benefits occur anytime soon if solely using this. The vitamin C used is again sodium ascorbyl phosphate, making it very stable, and aside from water the other hero ingredient is cannabis sativa seed oil, bringing in the moisturising properties of vitamin it felt instantly cooling on the skin with a milky-looking odourless formula, we would only recommend this to those at the very beginning of their skincare journey rather than beauty buffs looking for serious reading...La Roche-Posay pure vitamin C10 serum for sensitive skinBest For sensitive skinSize 30mlScented YesLa Roche-Posay is quickly becoming one of our skincare favourites with a huge range of affordable products that do exactly what they say on the tin. And, if it’s growing on you too then you may want to add this vitamin C serum to your basket. Combining 10 per cent ascorbic acid, salicylic acid and hydrolysed hyaluronic acid, it’s built to reduce signs of ageing – tackling fine lines and wrinkles and plumping skin with pipette wasn’t our favourite and is a bit tricky to get the liquid drawn up into it, but the light citrusy scent, weightless feel and instant absorbency of the serum had our tester reaching for this over and over reading...

Rightfully so, given the number of products on the market and the numerous internet skincare gurus sharing their advice about the how-to’s of getting the most out of the antioxidant, given the fact the powerhouse ingredient actually yields visible results. These results aren't anecdotal. They're scientifically backed. Vitamin C is clinically proven to protect against free radical damage caused by pollution, sunlight, and even alcohol while effectively evening skin tone and promoting collagen production. Even with all of the above mentioned, you may still have questions about selecting a vitamin C serum for your routine. Let's start with some expert-backed information about this ingredient. "Translated to real life, vitamin C is a workhorse for looking great," Christina Lee Chung, MD, FAAD, board-certified dermatologist at Schweiger Dermatology Group in King of Prussia, tells PEOPLE. However, to get benefits like improving wrinkles, evening out skin tone, and helping with skin sagging, Chung says consistency is key. So using vitamin C daily can be a game-changer for your skin. Below you’ll find 13 serums that were PEOPLE Tested for six weeks and scored on attributes like ease of use, absorption, skin texture and glow, firming ability, overall look, and value.

This fragrance-free anti-aging serum features 10 percent vitamin C, with over 3,000 users writing five-star reviews of the fast-absorbing, skin-mattifying formula after seeing visible results. During our tests, we found that while the serum didn’t yield immediate results like other serums we tried, it offered longer-lasting results. Over the course of a few months, this L'Oreal serum drastically improved our tester's skin's radiance. “I've paid this much for other vitamin C serums that were half as effective, so I think this is a great price for this product," she said. On top of that, this serum melted into our skin without any stickiness or added weight and had an immediate glowing and smoothing effect. Plus, unlike pump containers, the L'Oreal Revitalift tube shape prevents you from wasting any serum because you can squeeze every last drop out of this affordable product.

Why you ask? Firstly, the science and clinical testing behind the brand's products In this serum's cases, it's patented and clinically proven to reduce combined oxidative damage from free radicals generated by UV, Ozone, and diesel exhaust by up to 41 percent. Additionally, the serum improves signs of photodamage, lines, and wrinkles while brightening the skin and even fading dark spots. Though this didn’t earn our highest score — it was close at — we found that this product is worth the hype. Not only is it brightening and glowifying, but it smoothes fine lines and texture on our skin. We do want to call out that our tester, who has used vitamin C daily in her morning routine for eight years, wasn’t expecting a notable difference. However, they were pleasantly surprised “I ended up seeing a difference in the texture of my skin and fine lines during this six-week test. Everything is a bit smoother and softer — this is the only product/step that One other thing we noticed about this product the odor.

For sensitive or breakout-prone skin, this dermatologist-developed, allergy-tested, non-comedogenic formula has all the necessities that lead to healthier, brighter skin, including 10% L-ascorbic acid, hyaluronic acid, skin barrier-protecting ceramides, and soothing vitamin B5. Our tester absolutely loved this product and said she will continue to use it at home until she uses the very last drop. She did note that the packaging can be tricky because while it's securely packaged for delivery, there are a few steps to opening the cap that took a second to figure out. But her acne-prone skin with post-breakout hyperpigmentation saw a reduction in the appearance of those spots while the formula felt light on the skin.

The brand's proprietary C-Firma is designed to be mixed by you before its first use. This helps maximize potency and keep the antioxidant complex of the L-ascorbic and ferulic acids fresh; each bottle is proven to maintain almost 95 percent efficacy up to one year after mixing. As for real-world results, we found that our skin was softer and plumper by the end of the six weeks, and our monthly chin breakouts were significantly reduced. One of our testers even started receiving compliments on her skin and said after three to four weeks of use, she'd catch herself in the mirror and think, "Wow, my skin looks so bright and smooth!" That self-confidence boost helps justify the price tag. However, this Drunk Elephant serum has a 15 percent vitamin C concentration, so if you're just starting out with a vitamin C step in your skincare routine, it's better to start with a 10 percent concentration.

Star ingredients 15% Vitamin C Ethyl Ascorbic Acid, PHAs, and hyaluronic acid People / Ivy Ford Things to Consider Before Buying Vitamin C Serum Concentration Level and Skin Type Most everyone can benefit from layering vitamin C into their routine. However, if your skin is reactive or sensitive, Chung says to avoid high-concentration formulas as they may cause irritation. So what exactly is a high dose? Formulas with 15-20 percent vitamin C are considered a higher dose. So, stick with a 10 percent concentration if this is your first experience with the antioxidant or if you have more reactive skin. You can always work your way up. Our top pick, L'Oreal Revitalift Vitamin C Serum, has a 10 percent vitamin C concentration. Other Ingredients Vitamin C is usually thoughtfully formulated with complementary ingredients. The reason for this? "Vitamin C products often need oiler vehicles to maintain stability," Chung tells PEOPLE. However, she notes this can be problematic for some skin types think acne-prone skin. But luckily, brand founders and chemists are considering a range of skincare needs. So if you are acne-prone, seek formulas with squalane and rosehip oils, as they are And as far as the actual vitamin C goes, Chung recommends products that use L-ascorbic acid as its active ingredient, preferably with vitamin E, for the best stability. This is because L-ascorbic acid is the most potent and effective form of vitamin C. Our best daytime serum, Drunk Elephant C-Firma Fresh Vitamin C Day Serum, contains both L-ascorbic acid and vitamin E. Retinol Products When should you apply vitamin C serum? That depends on what other products you’re using as well as your skin sensitivity level. Chung recommends her patients use Vitamin C in the morning. However, she tells us it can be applied at night with another skincare must-have "If I'm going to use either retinol or Vitamin C, I'll take retinol," she shares. However, Chung does note this pairing can be a dynamic duo that gets you a little more bang for your buck if your skin isn't prone to irritation. "Retinol is your gold standard for increasing collagen and improving the turnover of skin cells while Vitamin C acts as a supporting cast," she explains. Prone to irritation? No problem. Instead, stick with vitamin C for the daytime and retinol at To find the best vitamin C serums on the market, our team used them over a period of six weeks. We tested 32 vitamin C serums altogether on a variety of different skin types. Of the 32 serums tested, seven earned a or above, and the ratings ranged from a 2 to a We rated each serum on ease of application and absorption. Then we noted how it interacted with our skin texture and whether it produced a glow or had firming capabilities. We then gave it a general rating based on the overall look of the applied vitamin C serum. Finally, the prices were revealed and we compared the retail price against the quality of the product to get our value rating. All in all, we selected 13 vitamin C serums we feel confident would work well for a variety of people. Frequently Asked Questions How often should I use vitamin C? Darden says a slow start is best if you're starting a vitamin C serum for the first time or adding a new vitamin C serum you haven't tried. "Vitamin C is a very active ingredient, and it can cause irritation," she explains. "Introducing it slowly will allow time for your skin to acclimate to the product without causing any irritation. Additionally, adding the product in slowly and by itself will make it easier to pinpoint how well it works for your skin. If you're adding in too many products at the same time, it can make it difficult to understand whether or not a product is working." So, how and when should I use vitamin C serum? Learning how to layer products and when to use them is a science, but once you get your routine down, it’s super simple. Chung encourages her patients to use vitamin C serum in the morning, but you can also apply it at night with a retinol. If your skin isn’t prone to sensitivity, the combination of vitamin C and retinol may give you faster results. In you are susceptible to irritation, use a vitamin C serum in the morning and a retinol at is one must when using vitamin C and caring for your skin in general SPF. "I recommend using vitamin C every morning before sunscreen," Los Angeles-based celebrity esthetician Shani Darden tells PEOPLE. "During the day, you want to protect your skin while you're out and exposed to environmental stressors. The combo of vitamin C serum and sunscreen is perfect for daytime protection." Among her favorite vitamin C-infused serums is iS Clinical Pro-Heal Serum. She notes it's an efficacious yet nourishing serum formulated with L-Ascorbic acid, a pure and potent form of vitamin C. It is also usually well-tolerated by most skin types, including those with sensitive skin. Why Trust PEOPLE?

What We Like Absorbs quickly into the skin Wears well underneath makeup and doesn’t pill No sticky residue What We Don't Like Product can build-up in the dropper Strong fragrance Might cause skin irritation or breakouts If you’re looking for an affordable vitamin C serum that will hydrate the skin and absorbs well, this is a great product to incorporate into your daily skincare routine. We put the InstaNaturals Vitamin C Serum to the test after receiving a complimentary sample from the brand. Keep reading for our full product review. Dermatologists can’t rave enough about vitamin C serums and there’s good reason for it. From brightening your skin to helping in reducing dark spots and uneven texture, vitamin C serums have been widely used in daily skincare routines and aren’t going away anytime soon. If you’re in the market for a new vitamin C serum or you’ve never tried it for yourself, we’ve tested one of the most popular and affordable serums out there, and the results are absolutely worth testing it out for yourself. Ahead—our real thoughts on InstaNaturals Vitamin C serum and all the reasons why it might be worth space in your skincare regime. About My Skin I'm a daily vitamin C user I have combination and sensitive skin with type 1 rosacea. I use a vitamin C serum every single morning after cleansing and before sunscreen. I don’t have any texture issues at the moment, but it’s important for me to continue to protect my skin at all costs and help brighten up my complexion. The most notable vitamin C serum I’ve used in the past is Skinceuticals C E Ferulic Acid Serum. One of the greatest attributes of the serum is how well it wears under makeup and it absolutely doesn’t pill. My skin looked hydrated and bright, which are two incredible results. Byrdie / Ashley Rebecca How To Apply Pat it in with your fingers After cleansing you’ll want to dispense a dropper full on the palms of your hands and pat all over the face and neck if you choose until the serum is absorbed. While a lot of people tend to rub skincare products in, you can also choose to do that if you’re more comfortable with it. I will say that patting the serum helps the skin to absorb it well. Wait until the serum has fully dried before moving onto your moisturizer. If you only want to wear the serum, it’s best practice to follow up with sunscreen as your last step. Byrdie / Ashley Rebecca The Results My Skin Felt Hydrated A few things I noticed after applying the serum were how quickly it absorbed into my skin and that it wasn’t sticky or greasy. I am not the biggest fan of strong fragrance in my skincare products, so it’s important to keep in mind this serum does have fragrance for anyone who might be sensitive. There are some days that I applied makeup right after the serum, and others that I applied sunscreen and then my makeup to test out how well it worked with foundation and concealer. Byrdie / Ashley Rebecca The Value Too good to be true For the ingredients this serum contains and how well it wears on the skin, the price of $22 feels almost too good to be true. It’s an incredible value for the results it gives and is incredibly budget-friendly for skincare making it a total win in our book.
