People / Kristin Kempa Vitamin C is one of the most searched skincare ingredients on the ‘net. 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.

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.

This particular serum can be used morning or night, but we prefer to use it in the morning for the light grapefruit scent and instant skin-brightening boost. However, if you prefer non-scented serums, you should opt for another pick on our list. Price at time of publish $ Size oz.

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. It has what might be described as a sour scent, akin to the smell of a hot dog. Price at time of publish $182 Size 1 oz.

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. She even noticed a reduction in fine lines around her mouth area. Price at time of publish $ Size 1 oz.

We found the Klur vitamin C serum to be super hydrating and smoothing upon application, and it was easily incorporated into our daily skincare routine.

However, this $27 dark spot serum is relatively budget-friendly and is packed with a powerful blend of 70 percent fresh green tangerine extract an ingredient that offers 10x more vitamin C than lemons, 4 percent niacinamide, and arbutin that helps improve dark spots and post-acne hyperpigmentation. We saw a difference in the texture of our skin after just a few days of use, a visible improvement in skin tone, and a reduction of dark spots.

It's like a lush smoothie for your face that won't clog pores— though our tester shared the formula didn't completely stop acne from occurring. However, the serum did help acne flare-ups dissipate more quickly than before adding this product to their routine. If you try to avoid oil-based products, this one might not be for you.

In testing, we saw brighter, dewier, and healthier skin in just a few Of all the serums we tested, this one definitely had a "wow" factor, and our tester felt that her skin looked younger after using this product for a few months. However, if you have oily skin, this might not be the best serum for you, and it's packaged in a glass bottle, which made our tester a little nervous that she might shatter it at any moment.

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. Also, one of our testers noted an odd smell upon application but said it quickly faded. Price at time of publish $78 Size 1 oz.

If scent is a vital factor in your skin products, you'll love that this serum wakes up your senses and brightens the skin. Formulated with vitamin C, skin barrier protecting niacinamide, and hydrating peptides, the citrus-scented formula is clinically proven to help skin look visibly more hydrated in one day and brighter after one We loved that this serum resulted in visible hydration and brightening effects and even after several hours, our skin felt refreshed. It had an immediate glowing effect, but it faded within an hour, so if glowing skin isn't your top priority, but feeling refreshed and hydrated is, this is a great value pick.

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?

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.

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.

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.

With 23% L-ascorbic acid—paired with moisture-boosting hyaluronic acid—this product combats uneven tone, boosts radiance and gives an overall plumping effect. The texture, however, can be divisive. It’s somewhat watery but also has a gritty feel, almost like an exfoliant. The right play here may be to use this one before bed, because when I tried to wear it under makeup, it pilled.

How To Choose A Vitamin C Serum Vitamin C is one of those antioxidants that’s especially compelling because it has so much potential to deliver complexion-enhancing results. There are many factors to consider when looking for the best vitamin C serum. “Choosing the right one can be tricky,” says Pritzker. “Beyond the efficacy of the [ingredient], it’s important to find a formula that works with your skin.” Clinical Data “There are many factors that go into formulating an effective vitamin C because it can be hard to stabilize,” says Pritzker. “These factors include pH, concentration and other ingredients. It’s important to make sure that the manufacturer has clinical data to back up its claims.” Ingredients Not all of them are created equal. Certain formulations offer higher concentrations, or they’re coupled with other star ingredients that give major benefits. Companies use various forms of vitamin C in their formulations, and the two most common are L-ascorbic acid and THD ascorbate. L-ascorbic acid is 100% pure vitamin C. It’s water-soluble, well-researched and effective, but extremely unstable. It begins to oxidize and change color over time and can be irritating to some people’s skin. Tetrahexyldecyl THD ascorbate is stable and fat soluble, so it can be used in oil-based products. It tends to be well tolerated and permeates the skin easily. Separately, vitamin E and ferulic acid are ideal antioxidants to be paired with vitamin C, according to Pritzker. Hyaluronic acid and squalane can also be vehicles within various vitamin C serums as well. Formulation “Vitamin C products have different vehicles that may or may not agree with your skin. There are creams, serums, oils, and depending on these factors some skin types react differently than others,” says Pritzker. Serums, for their part, are typically characterized by highly concentrated ingredients that penetrate deep within the skin. Packaging Because vitamin C is often an unstable ingredient and can start to oxidize in the presence of light, heat and air, it’s a good idea to seek out serums with dark, opaque packaging. If the formula itself has turned brown, it has lost its potency. Which Brand Of Vitamin C Serum Is Best? When it comes to skincare, choosing a formula largely depends on your skin type, goals and budget. Luckily, the vitamin C serum category runs the gamut in ingredient concentration, price point and consistency. Identifying the right concentration for your skin type will determine how effective your serum will be, and starting slow could help ease your skin into this new regimen. Consider starting with a lower dose of 10% before increasing to 15% or 20%. Additionally, if you have normal or oily skin, consider using L-ascorbic acid, the most potent form of vitamin C—found in our best overall pick, SkinCeuticals’ C E Ferulic. However, if your skin is dry or sensitive, opt for magnesium ascorbyl phosphate, a water-soluble vitamin C, which can be less irritating. Do Dermatologists Recommend Vitamin C Serum? The results for vitamin C speak for themselves. “From clinical data as well as anecdotal evidence, we know that it works,” says Pritzker. “You can start to appreciate the results of a topical vitamin C in as little as a month.” If your skin is dull or lackluster, vitamin C is the gold standard of brightening ingredients because of its ability to inhibit the production of pigmentation, even skin tone and fade dark spots. When applied topically, the potent antioxidant neutralizes free radical damage and protects the skin against UV light and other environmental aggressors. And while it’s best known for brightening, it also promotes the synthesis of collagen, the protein that builds your skin structure. This makes vitamin C instrumental in firming and preventing the loss of elasticity, as well as the healing of acne wounds. What’s The Best Way To Use Vitamin C In Your Skincare Routine? Experts recommend using it as a first step. “As with most actives, I recommend using a vitamin C after cleansing but before non-active topicals,” says Pritzker. “So you should use it before you moisturize and always before SPF, which you should be using every day. We typically recommend using it in the morning.” It can also be used daily, “as long as it is tolerated well and not irritating the skin or causing an adverse reaction,” says Pritzker. However, if you’re new to the vitamin C serum scene, it may be best to start at a lower concentration or apply it less frequently because it can cause irritation. “You should not use vitamin C on compromised skin,” she says. You also need to be cautious using it with other actives, such as retinol. For even more great deals on skincare products, check out Forbes Coupons.
