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.

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, 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.

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.

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.

The epidermis turns over approximately every 48 days and the turnover time increases as we age,” explains Dr Ginni.“For this reason it will take time to see effects. Plus giving vitamin C the entire job of correcting skin brightness, fine lines and wrinkles is a huge ask. We suggest combining it with niacinamide, vitamin A and Alpha Hydroxy Acids AHAs for best effects. We find our customers will have better FEELING skin within a week, but you will start to SEE changes in three weeks. Pigmentation takes much longer – usually months.”CAN YOU USE VITAMIN C SERUM EVERYDAY?Yes, you can use vitamin C serum everyday. “There is evidence from trials in using it once daily, especially in the morning where it works to prevent sun damage. There is no evidence for using it more often than that,” says Dr Ginni.“As a serum, it is your thinnest product so would be applied straight after cleansing. Your SPF product should be applied last.

Byrdie / Marcus Millan With so many different types of serums and skincare actives on the market, it can be tricky to navigate what each one does and whether or not it should hold a place in your skincare routine. When it comes to vitamin C serums, board-certified dermatologist Diane Madfes, MD, is a fan of them, citing their efficacy. "They work to stimulate collagen, lighten dark spots, and protect against sun damage," Madfes tells Byrdie. "They're also great for fine lines, melasma, and rosacea." Vitamin C in serum form is so effective because it attacks free radicals that can damage skin DNA. But with so many to choose from, it can be tricky to decide which one is best for you. So, after putting dozens of them to the test in our lab and choosing our favorites based on various attributes, we decided to send them home with our testers so that they could gain even more meaningful insights over the course of six weeks. They each evaluated one vitamin C serum during that time period based on ease of use, absorption, skin texture, skin glow, firmness, and overall look. Those that scored the highest appear on this list. Target Our Ratings Ease of Use 5/5 Absorption 5/5 Skin Texture 5/5 Skin Glow Firming 5/5 What We Like Packaging is functional and makes dispensing ideal amount of product easy Doesn’t leave sticky residue behind Improves skin’s radiance with time Helps to smooth skin texture What We Don't Like Doesn’t leave the skin looking immediately glowy Good skincare shouldn’t be difficult to find, and we love that this extremely accessible product is more than just available in your local drugstore and relatively affordable—it’s also highly effective. Over time, our tester noticed a significant improvement in the radiance of her complexion, noting that after the six weeks, her skin appeared brighter and more smooth. She was also pleasantly surprised that although wrinkles and firmness were not a big concern for her, she did see a noticeable difference in the firmness of her skin. “I'm a huge fan of this product and will definitely be buying it over and over again when I run out. My overall complexion is way brighter and smoother, and I love how the product melts into the skin when applied,” she shared. As for the texture of the product, it’s not liquidy nor oily; rather, it almost feels like a lightweight paste. While this might not sound super appealing, it spreads easily and sinks into the skin quickly. Our tester also noted that she appreciated the squeeze-tube packaging, saying it made dispensing the right amount of product easy. The one con of this product is that, unlike some other vitamin C serums that immediately leave the skin looking radiant due to oily or luminous formulas, this one doesn’t. But given how effective it is over time, this isn’t a major downfall. Price at time of publish $33 Benefits Radiance-boosting, wrinkle-reducing Skin Type All Dosage Apply a dime-size morning and evening Size 1 ounce Cruelty-Free No Byrdie / Samantha Jones Bluemercury Our Ratings Ease of Use 5/5 Absorption 5/5 Skin Texture 5/5 Skin Glow 5/5 Firming What We Like Lightweight formula is fast-absorbing Doesn’t create a greasy residue Improves fine lines and textures over time What We Don't Like While it doesn’t contain fragrance, it has a naturally unpleasant scent Sometimes the most buzz-worthy products don’t live up to expectations, but this one does. It has a lightweight, fast-absorbing formula that doesn’t feel sticky or drying on the skin, it’s easy to apply and layer in a skincare routine, and it creates some really impressive results. While our tester has been using vitamin C serums consistently for many years, she explained that when she switched to this one, she noticed a very real improvement in the texture of her skin, as well as a reduction in the appearance of fine lines. After six weeks of using it, her skin looked and felt softer and smoother. She also mentioned that it did contribute to the glowiness of her skin, but not significantly more so than other, more affordable options she's used. There’s no denying that our tester, as well as several of our editors, adore this serum, but it’s worth noting that while it doesn’t contain fragrance, the ingredients mixed together do create an unpleasant scent. However, the scent doesn’t linger on the skin for long, so it’s not a dealbreaker for us.

The formula is packed with antioxidant-rich grapefruit and vitamin C, as well as polyhydroxy Acids PHAs, which work to gently break down dead skin cells. Our tester adored this serum, saying it sunk into her skin with ease while leaving it feeling moisturized, and she also noted that after each application, her skin looked radiant. In terms of the long-term results, she was thrilled with how well this serum worked to brighten her complexion and smooth her skin texture. She noticed a visible improvement in texture in just a few days, and at the end of the testing period, she said her skin felt soft and slightly more firm, and her skin tone looked even.

This one is fantastic for beginners because it contains vitamins C and E, as well as marine peptides known for their firming effect. The formula is also foolproof—it absorbs quickly, leaves the skin feeling comfortable, and layers nicely under other makeup and additional skincare products. Our tester, who was weary of using this type of product, was really pleased with her experience using it, as well as the results it gave her. She explained that the dropper was intuitive, and the formula sunk into her skin quickly without leaving behind a sticky or greasy residue. After just a week or two, she recognized a real difference in the brightness of her skin, noting that her complexion looked more radiant even when she wasn’t wearing it. It helped her achieve more luminous, healthy, and youthful-looking skin. While it doesn’t have hard claims on firming benefits, we would love it if it provided a bit more of a firming benefit, especially considering that it contains marine peptides. However, it’s an excellent product overall, and we think it’s the perfect pick for vitamin C beginners.

This one is just that, and our tester loved it. Not to mention, tons of our Byrdie readers adore this one. Our tester has fairly sensitive and acne-prone skin, and she raved about how comfortable this serum felt as she applied it. While it took about 30 seconds to dry, which is slightly longer than some other options, it dried down to a moisturizing and non-greasy finish. She even noted that she could get away without applying a moisturizer on top of it, and her skin would still feel hydrated. Another bonus? It didn’t clog her pores. As for the results after the testing period, our tester was really pleased with them. She explained that her post-acne marks were noticeably lightened, and her complexion looked radiant. Considering that it’s effective, non-irritating, suitable for all skin types, and doesn’t contain harsh acids, we think it’s a great choice for people with sensitive skin.

Our tester with acne-prone and oily skin absolutely loved her experience testing this serum, claiming that the formula, which is suitable for all skin types, didn’t contribute to breakouts; rather, it helped to improve the appearance of her skin overall. The formula contains L-ascorbic acid, the purest form of vitamin C for powerful antioxidant protection, as well as hyaluronic acid for an added boost of hydration. While she struggled a bit to set up the dispensing part of the packaging for the initial use, once it was complete, she said the product was easy to use moving forward. She appreciated that the serum had a lightweight texture that didn’t feel greasy on her already oily skin, and she noticed that after a few weeks of using it, her post-acne marks were visibly lightened. She also loved that her skin looked slightly brighter after consistent use, and the fine lines near her mouth appeared to have smoothed out a bit.

It’s not a harsh formula that contains potentially irritating acids; rather, it’s a gentle product that actually makes a noticeable improvement in the texture and tone of the skin. Our tester, who’s in her sixties, raved about how much this product helped firm her skin. Not only that, but she noticed a real improvement in her skin texture, saying that after the six-week testing period, her face looked and felt smoother and softer overall. While she didn’t see a major difference in the radiance of her skin, the texture and tone improvements are so great that this isn’t a deal breaker for us. We also love that it’s housed in an amber glass bottle which helps to prevent UV oxidation and therefore protect the potency of the product and ensure it lasts.

This one, in particular, is great for brightening because it leaves the skin with a glow right after application, and it helps to improve the skin’s radiance over time with consistent use. We appreciated how user-friendly the packaging is, that the texture is absorbs into skin quickly and that it leaves you feeling moisturized and looking glowy. It also layers beautifully with other skincare and makeup products. After the six-week period, our tester's skin was left looking hydrated, glowing, and refreshed. While the serum claims to help with skin plumpness, thanks to the inclusion of hyaluronic acid in the formula, we didn’t notice a visible improvement in this area. But given how brightening this serum is, we highly recommend it if you’re dealing with dull skin.

But if you have fairly surface-level dark spots, we highly recommend incorporating a vitamin C serum into your routine because the powerful antioxidant has been known to help lighten hyperpigmentation. This one is excellent for that because, in addition to containing vitamin C, it’s also formulated with niacinamide, another ingredient known for its spot-fading capabilities. This formula is suitable for all skin types, has a lightweight and non-oily finish, and the packaging is simple and effective. Over time, our tester recognized a significant reduction in the appearance of her post-acne marks, saying her complexion looked generally more even in tone. She also noted that her skin texture felt more even to the touch. While our tester didn’t complain about it, beware that some online reviewers noted that the citrus scent of this serum is a bit overpowering.

The formula feels like a typical, lightweight facial oil—as opposed to some vitamin C serums that have more gritty textures—and it nourishes the skin in addition to providing all of the wonderful antioxidant benefits. Despite having oily skin, our tester didn’t feel that this formula made her face look or feel greasy, rather, it provided the necessary hydration and a bit of glow. Over time, she noticed a real improvement in the radiance and texture of her skin, even saying that it seemed to blur the look of her pores and uneven texture with continued use. The one thing we think is missing? It didn’t do much in terms of firming the skin, but if improving radiance and skin texture is your goal, we don’t think you’ll be disappointed with this product.

It has a lightweight texture that’s packed with vitamin C for antioxidant protection, pomegranate stem cells to aid in dark spot reduction, and a blend of greens to nourish the skin. Once applied, it doesn’t make the skin look immediately radiant, but our tester shared that over time, she did notice an improvement in the overall brightness of her complexion. She also noted that it helped to visibly reduce some of her hyperpigmentation, resulting in a more even, less dull-looking skin tone. Price at time of publish $32 Benefits Brightening, firming, texture-smoothing Skin Type Balanced, dry, combination, oily Dosage A few drops daily Size 1 ounce Cruelty-Free Yes Final Verdict The L’Oréal Paris Revitalift Derm Intensives Vitamin C Serum is our top pick due to its accessibility, functional packaging, and effectiveness at improving skin tone and texture. If you prefer an oil-based product that will really boost the radiance of your skin and keep it hydrated, we recommend the Biossance Squalane + Vitamin C Rose Firming Oil. And if you’re totally new to using vitamin C in your skincare routine, the Sephora Collection Glow + Strengthen Vitamin C Serum is a great choice for you. How We Tested Over the course of six weeks, each tester incorporated one vitamin C serum into their beauty routine per the directions on the packing of their product. They evaluated their serum based on ease of use, absorption, skin texture, skin glow, firmness, and overall look, and those that scored the highest earned our Byrdie stamp of approval and appear on this list. Other Options We Tested Paula’s Choice C15 Super Booster While our tester appreciated that this liquidy serum absorbed quickly and layered nicely in her skincare routine, she didn’t see a noticeable difference in the brightness of her complexion or a reduction in dark spots. Sunday Riley 15% Vitamin C Brightening Serum Despite enjoying the results of this popular vitamin C serum, our tester had trouble recommending it because there are other more affordable options on the market that yield the same results. Hyper Skin Brightening Dark Spot Vitamin C Serum Though this brightening serum did a nice job of boosting the radiance of our tester’s skin, she didn’t see an improvement in hyperpigmentation or firmness after the six-week testing period. Meet the Expert Jessie Cheung, MD is a board-certified dermatologist specializing in dermatological surgical and cosmetic procedures based in Willowbrook, IL. Jennifer Herrmann, MD is a board-certified, fellowship-trained dermatologist and dermatologic surgeon based in Beverly Hills, CA. Diane Madfes, MD, is a New York City board-certified dermatologist and assistant professor of dermatology at the Mount Sinai School of Medicine. What to Look for in a Vitamin C Serum Opaque Packing Vitamin C is inherently unstable and quickly broken down when exposed to light and/or oxygen. For that reason, board-certified dermatologist Jessie Cheung, MD suggests looking for a product that comes in an opaque bottle—like the SkinCeuticals CE Ferulic Serum or the Klur Brilliant Light—or have an air-tight pump dispenser. Similarly, always make sure to store your vitamin C serum in a cool, dark place. L-Ascorbic Acid To get the most value from your vitamin C serum, Dr. Cheung suggests looking for this type of vitamin C, the most potent and active version. That being said, it is often pricey and comes with the highest likelihood of irritation. Other less intense versions include sodium ascorbyl phosphate and magnesium ascorbyl phosphate. The Skinceuticals C E Ferulic is a great option with L-ascorbic acid as is the CeraVe Skin Renewing Vitamin C Serum. Other Antioxidants Vitamin C works synergistically, meaning it plays very nicely with other antioxidants. Common antioxidants found in vitamin C serums include vitamin E and ferulic acid, says Dr. Cheung. In particular, she says these two increase the efficacy of vitamin C and help stabilize it. The Klur Brilliant Light is a great option that includes vitamin E. FAQ What does vitamin C serum do? According to board-certified dermatologist Jennifer Herrmann, MD, vitamin C has three main functions. The first is protecting against environmental stressors and free radicals, an antioxidant benefit that slows signs of aging and reduces damage overall. Vitamin C also promotes collagen production, giving skin more support and structure. Finally, it’s a radiance-boosting agent, so a serum that features it can work to even skin tone and fade hyperpigmentation. When should you apply vitamin C serums? There has been much debate about whether it’s better to use the ingredient to protect skin during the day, or replenish it at night, but Dr. Herrmann says you can choose which time of day to apply— just be consistent. How should you apply vitamin C serums? Dr. Herrmann recommends applying your serum after cleansing. Additionally, avoid using it at the same time as certain other active ingredients such as benzoyl peroxide. For example, if you use a benzoyl peroxide product at night, it’s best to apply your vitamin C serum in the morning. How often should you apply vitamin C serums? According to Dr. Herrmann, you should apply vitamin C serum either daily or every other day, depending on your routine and the result you want. If you already alternate several other actives, you might apply it every other day; if you’re looking to dramatically fade hyperpigmentation, you may want to use it daily.
