The 7 Best Vitamin C Serums We Tested and Recommend for Glowing Skin
With so many serums on the market, it can be hard to know what each product does and decide if it deserves a spot in your skincare routine.
If you want to invest in just one product, board-certified dermatologist Dr. Diane Madfes recommends a vitamin C serum.
One of the main benefits of vitamin C is protecting the skin from environmental factors like UV rays and pollutants, which can damage the skin through free radicals.
It’s a powerful antioxidant that can lead to a smooth, clear, even-toned complexion with regular use.
“They stimulate collagen production, reduce dark spots, and protect against sun damage,” Madeface told Birdie. “They’re also very effective for treating fine lines, melasma, and rosacea.”
We tested dozens of vitamin C serums in our lab and at home for six weeks as part of our daily skincare routine, evaluating each product on ease of use, absorption, skin texture, radiance, firmness, and overall appearance.
Finally, we asked two nationally certified dermatologists, Dr. Jessie Cheung and Dr. We consulted with Jennifer Herrmann to pick out the seven best products for glowing skin.
Best Overall: L’Oréal Paris Revitalift Derm Intense Vitamin C Face Serum
We love that this product is available at the drugstore, relatively affordable, and highly effective. Over time, we noticed a significant improvement in the radiance of our complexion.
After six weeks, our skin looked brighter and smoother. The firmness of our skin was also noticeably improved.
The texture of the product is neither liquid nor oily. It feels more like a light paste. This may not sound particularly appealing, but it spreads easily and absorbs quickly into the skin.
We also love the squeeze tube, which makes it easy to dispense the right amount of liquid.
The only downside: Unlike other vitamin C serums, which leave skin instantly glowing due to their oily or shine-inducing formulas, this product doesn’t. However, considering the long-term effectiveness, this isn’t a major downside.
Who’s it for?
This product is a great all-rounder for those who need a little more oomph. However, it’s best suited for those who are patient, as results take some time.
Best Treatment: SkinCeuticals C E Ferulic
As big fans of vitamin C serums, we knew a good formula when we tried it. Sometimes the most hyped products don’t live up to expectations, but this one certainly did.
The lightweight, fast-absorbing formula doesn’t feel sticky or dry on the skin. It’s easy to use and incorporate into your daily skincare routine, and it delivers impressive results.
Using SkinCeuticals C E Ferulic, we noticed a noticeable improvement in skin texture and a reduction in fine lines. After six weeks of use, our skin felt softer and smoother.
However, we’re not convinced that this product brightened our complexion any more than other, cheaper products we’ve used.
We undoubtedly loved this serum, but it’s worth noting that while it’s fragrance-free, it doesn’t have a particularly appealing scent. However, since the scent doesn’t cling to the skin, it didn’t bother us.
Who’s it for?
This SkinCeuticals serum is a great choice for those who are concerned about fine lines and photoaging. Vitamin E (alpha-tocopherol) and ferulic acid enhance the formula’s protective properties against environmental damage caused by free radicals.
Best Budget: Yes Grapefruit Daily Brightening Serum
This serum proves that you don’t have to spend a ton of money on skincare to make a positive difference in your skin.
The formula contains antioxidant-rich grapefruit and vitamin C along with polyhydroxy acids (PHAs) to gently exfoliate dead skin cells.
We loved this serum. It absorbed quickly and hydrated the skin. We also noticed that our skin looked radiant after each use.
We were happy to see that this serum was effective in brightening our complexion and smoothing our skin texture over time.
After just a few days, we noticed a noticeable improvement in the appearance of our skin. At the end of the test period, our skin felt softer, firmer, and our skin tone was more even.
Who is it for?
If you’re looking for an affordable vitamin C serum, the Yes To Grapefruit Daily Brightening Serum is your new favorite.
Best for Beginners: Sephora Collection Super Radiance Serum with Vitamin C + E
If you’re using a vitamin C serum for the first time, it’s best to start with one that has a simple formula, is easy to apply, and doesn’t contain harsh ingredients that could cause irritation.
We love this one for beginners because the formula is so easy to use—it absorbs quickly, feels comfortable on the skin, and blends well with makeup and other skincare products.
It contains vitamins C and E as well as marine peptides, which are known for their firming benefits.
We found application with the pipette to be very intuitive, and the formula absorbed quickly into our skin without leaving any sticky or greasy residue.
After just a week or two, we noticed a noticeable difference in the radiance of our skin,
noticing that our complexion looked more radiant even without using a serum. Overall, it’s helping us achieve brighter, healthier, and younger-looking skin.
While there are no specific claims about firming effects, we’d expect this product to achieve a slightly stronger firming effect, especially considering the marine peptides it contains.
Still, it’s a great product overall.
Who’s it for?
This product is ideal if you’re using vitamin C for the first time and are concerned that your skin might be a little irritated during the adjustment period.
It doesn’t contain any additional active ingredients, so you can start a new treatment regimen with ease.
Best for Sensitive Skin: TruSkin Vitamin C Face Serum
If you have sensitive skin, you know how important it is to have a gentle yet effective product. That’s exactly what we value. Many of our Birdie readers are thrilled.
This product is perfect for sensitive and acne-prone skin. Although it only dries in about 30 seconds – a little longer than other products – it’s hydrating and non-greasy.
We even found that our skin felt moisturized even without using moisturizer.
Another plus: it didn’t clog our pores.
We were very happy with the results of our testing phase. Acne spots were visibly lighter, and our complexion became radiant.
Who is it for? Since it’s effective, non-irritating, suitable for all skin types, and contains no harsh acids, we think it’s a great choice for people with sensitive skin.
Best for Acne-Prone Skin: CeraVe Skin Renewal Vitamin C Serum
Anyone with acne-prone skin knows that trying new skincare products can often lead to breakouts and irritation. We found that this product really helped improve the overall appearance of oily skin.
The formula contains L-ascorbic acid (the purest form of vitamin C) for powerful antioxidant protection and hyaluronic acid for extra moisture.
While we had some trouble opening the dispenser in the packaging the first time we used it, the product was easy to use after that.
We were also pleased to see that with regular use, our skin looked more radiant and the fine lines around our mouth were smoother.
Who is it for?
This is a great option for acne-prone skin. We appreciated the lightweight texture of this serum, which didn’t make our already oily skin feel greasy.
After only a few weeks of use, we noticed a noticeable reduction in our acne spots.
Best for Firming Skin: Klur Brilliant Light Multi-Correction Repair Serum
Rather than a harsh formula with potentially irritating acids, Klur Brilliant Light Multi-Correction Repair Serum is a gentle product that visibly improves skin texture and tone.
We were thrilled with how well this product firmed our skin.
Additionally, we noticed a significant improvement in our skin structure; our face looked and felt smoother and softer after a six-week trial.
While we didn’t notice a huge difference in skin radiance, the improvement in skin texture and tone was so noticeable that we had no reason to worry.
Who is it for?
We recommend this vitamin C serum for all skin types, tones, and age groups, and it’s a top choice for anyone looking to firm and smooth skin.
