Additionally, the serum improves signs of lines and wrinkles while boosting radiance and even fading dark spots.Not only did it make our skin glow, but it also smoothed fine lines and texture on our skin. It also pairs well with other products you may already have in your routine and doesn’t leave a sticky residue.

We do want to point out that our tester, who has used vitamin C daily for eight years, wasn’t expecting a notable difference. However, she was 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 changed.” One other thing we noticed about this product is the odor, but that won’t stop us from brighter skin.

Not great for those with oily skin

If natural ingredients are your jam, we have some good news. This fast-absorbing serum is made with 97 percent naturally sourced ingredients, including natural forms of vitamins C and E alongside peptides derived from marine algae that firm and hydrate to combat and smooth wrinkles.

In testing, we saw dewier and healthier skin in just a few weeks. Of all the serums we tested, this one definitely had a “wow” factor, andour 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. But from our standpoint, this product, which provided a vast skin improvement from a non-plastic bottle is a fantastic deal.

After six weeks our skin was softer, plumper, and more luminous, and our monthly chin breakouts were significantly reduced. One of our testers even started receiving compliments on her skin, and after just three to four weeks of use, started to notice a visible difference in her complexion’s brightness and texture.

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 lower dose (around 10 percent concentration). Also, one of our testers noted an odd smell upon application but said it quickly faded.

On the pricier end

In testing, we found that even testers with naturally oily skin loved this product, saying that the oil absorbed surprisingly well and never felt greasy post-application. The glow of this serum is excellent at combating dull skin, andone of our testers said she’d received so many compliments on her skin since incorporating this product into her daily routine. It also made her skin extra plump, as if she’d just gotten a great night’s sleep. This product is on the more expensive side, but a little goes a long way, so we think it’s worth it.

What to Know About Vitamin C Serum

Yes, you can use it with retinol products.

If your skin is not sensitive, you can apply both vitamin C and retinol at night. “If I’m going to use either retinol or vitamin C, I’ll take retinol,” Chung shares. 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 aretinol formulaat night.

Opt for a low concentration if you have sensitive skin.

Most everyone can benefit from layering vitamin C into their routine, whether it be vitamin C serum or in aneye cream for dark circles. But if your skin is reactive or sensitive, Chung says to avoid high-concentration formulas that may cause irritation. Some vitamin C products are formulated specifically for sensitive skin, likeSkinCeuticals C E Ferulic. If you have dry skin, trySephora Collection’s Ultra Glow Serum, our top pick for dry skin.

Look for dark or opaque packaging.

Vitamin C serum that is packaged in a dark glass bottle or opaque plastic tube will last longer than one stored in clear packaging. It’s also important to store your vitamin C serum in a cool, dark place to avoid UV exposure, which can make it less effective. TheKlur Brilliant Light Multi-Correctional Repair Serum, which is in a dark glass bottle, and our best overall,L’Oreal Paris Revitalift Vitamin C Serum, in an opaque tube, are examples of the ideal packaging for vitamin C serums.

Consider the 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 (like acne-prone skin). So if you are prone to acne, seek formulas with squalane and rosehip oils, as they are non-comedogenic. Vitamin C can also be quite effective inhyaluronic acid serumsand can be used in conjunction withniacinamide products.

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.

To find the best vitamin C serums on the market, we gathered top-rated products and our team used them over a period of six weeks. We tested 32 vitamin C serums altogether on a variety of different skin types. All in all, we selected 14 vitamin C serums we feel confident would work well for a variety of people.

Frequently Asked Questions

There is one must when using vitamin C (and caring for your skin in general): SPF. “I recommend using vitamin C every morning beforesunscreen,” Los Angeles-based celebrity estheticianShani Dardentells PEOPLE. “The combo of vitamin C serum and sunscreen is perfect for daytime protection.”

The best time to apply vitamin C serum depends on what otherbeauty productsyou’re using as well as your skin sensitivity level. 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 with sensitive skin to use vitamin C serum in the morning, but you can also apply it at night with retinol. If your skin isn’t prone to sensitivity, the combination of vitamin C and retinol may give you faster results. If you are susceptible to irritation, use a vitamin C serum in the morning and a retinol at night.
