Vitamin C is an ingredient that should be part of everyone's skincare routine—regardless of age or skin type. It's known and loved for its brightening and anti-aging abilities, and dermatologists also tout it for being one of the strongest protective antioxidants out there.

While budget-friendly vitamin C serums certainly do exist, the majority of formulas skew on the expensive side. That said, they are totally worth the investment, as a highly concentrated vitamin C serum will ward off harmful environmental aggressors like UV rays, pollution, and smoke, while also reversing existing damage. They're also ideal for brightening and evening out a mottled complexion. "Vitamin C is a multi-tasking brightening agent as its antioxidant properties provide protection from ultraviolet light exposure, and it also inhibits tyrosinase, the enzyme that fuels melanin pigment production," explains Dr. Jessie Cheung, a dermatologist.

As a topical ingredient, vitamin C is volatile and breaks down when exposed to light or oxygen. So on that note, airtight, opaque packaging is a must to preserve product potency. Vitamin C also works well with other antioxidants, so products that combine it with other actives could work double-duty on your skin concerns. And don't forget to consider your skin type—stronger forms of the vitamin, like L-ascorbic acid, are potent but potentially irritating, while milder forms are ideal for sensitive skin.

Behold: The best brightening vitamin C serums to add to your skincare routine.

Our Cyber Monday vitamin C serum pick is the TruSkin Vitamin C Serum, which is currently $20 at Amazon, down from $30.

What Our Editors Say

"If I had to pick one skincare product to rave about, this is the one. The combination of ferulic acid and vitamin C and E works to protect against environmental damage caused by free radicals, improves signs of aging and photodamage, reduces the appearance of lines and wrinkles, and brightens my complexion each time I use it. It's a thin, watery serum and it doesn't smell great—but it works better than any vitamin C product I've ever used. Over the years, I've noticed an immediate (glowy, even skin the day after) and long-term (healthier, happier, smoother skin) result." —Hallie Gould, Associate Editorial Director

What We Like

• Plumps and hydrates as it brightens and smoothes

The best part? It's super effective, which is why scores of reviewers on Amazon can't get enough. And for the price, you really can't go wrong.

It also contains hyaluronic acid, which helps to hydrate and plump fine lines and wrinkles. Overall, it's a solid choice for improving uneven texture and tone, smoothing out the complexion, and protecting against environmental stressors.

What We Like

• Non-greasy formula is great for oily skin types

• Contains phloretin to neutralize free radicals and improve discoloration

What We Don't Like

• It's pricey

Say hello to the lesser-known cousin to SkinCeuticals C E Ferulic, Phloretin CF. Despite its insane following, many don't realize that C E Ferulic is actually best suited to those with dry and normal skin types. However, if you veer oily, this serum is actually a better option for your specific skin type.

"For normal to oily skin types, we recommend using this product over the C E Ferulic. Many people read rave reviews about C E Ferulic and don't realize that the Phloretin is a better match for their skin type!" explains Helen Koo, senior marketing manager of Dermstore. So what makes it so special? This serum contains a mix of vitamin C, ferulic acid, and 2% phloretin to help neutralize free radicals, encourage cell turnover, and lessen discoloration.

Benefits: Even skin tone, anti-aging, hydration | Skin Type: All skin types | Dosage: 4-5 drops once daily | Size: 1 fl. oz. | Cruelty-Free: No | Byrdie Clean: Yes

What We Like

• Formulated with a stable, oil-soluble form of vitamin C

• Contains glycolic acid to exfoliate

• Fades acne scars while preventing future breakouts

What We Don't Like

• It's pricey

While most vitamin C serums contain L-ascorbic acid, this one is made with the gold standard tetrahexyldecyl ascorbate, which is a stable, oil-soluble form of vitamin C. Albeit expensive, we highly suggest adding this mighty vitamin C serum to your lineup if you have acne-prone skin. In addition to its fancy strain of vitamin C, it also contains glycolic acid, which is known for its exfoliating ability.

The unique blend helps retouch discolored acne scars while also preventing future breakouts. Unlike most liquid vitamin C serums, this one has a thicker, richer consistency—almost like a moisturizer. That said, the formula melts right into the skin leaving you absolutely glowing.

Benefits: Even skin tone, anti-aging | Skin Type: Dry, combo, normal skin | Dosage: 2 pumps once or twice daily | Size: 1 fl. oz. | Cruelty-Free: Yes | Byrdie Clean: No

What We Like

• Contains pumpkin and pomegranate enzymes to gently exfoliate

• Has a soothing, cooling sensation

• Continues to work for 72 hours after applying

What We Don't Like

• Slightly sticky texture

This vitamin C serum contains a laundry list of high-quality ingredients. Pumpkin and pomegranate enzymes help with cellular turnover and gently exfoliate the skin while vitamin C and ferulic acid naturally brighten skin and help protect against damage. What's more, the cooling sensation of this clear gel soothes even the most inflamed, sensitive skin. After cleansing in the morning, spread a pea-sized amount all over your face, neck, and chest.

Fun fact: C-Firma has a reservoir effect on the skin, which means it continues to work for up to 72 hours and cannot be washed or rubbed off (we like to justify the price with this).

Benefits: Even skin tone and texture, anti-aging | Skin Type: All skin types | Dosage: 2-3 pumps once daily | Size: 1 fl. oz. | Cruelty-Free: Yes | Byrdie Clean: Yes

What Our Editors Say

"I've been using this vitamin C serum every morning for years now. The naturally amber-colored formula gives my skin a lovely, lit-from-within glow immediately upon application, and over time my skin has become more luminous and healthy-looking (even when I'm not wearing it). I'm prone to the occasional breakout, but I don't have any lingering acne scars, and I give 100 percent of the credit to C-Firma." —Holly Rhue, Editor

Overall, this serum boosts radiance and shine while creating long-term changes to the way your skin looks and feels. With regular use, the serum works to minimize fine lines, lighten dark spots, and overall increase the skin's brightness.

What We Don't Like

A favorite brand among the best dermatologists in the world (and often the brand of choice used in-office for more intensive treatments like chemical peels), PCA Skin is lesser-known on a commercial level. (Although it shouldn't be.)

We also love that this all-natural product is gentle enough to use morning and night.

Vitamin C, known for its brightening, antioxidant, and anti-aging abilities, is an ingredient that should be a part of everyone's skincare routine.

Don't want to spend so much money on a vitamin C serum? We (along with thousands of happy reviewers) are big fans of TruSkin Vitamin C Serum as well, and it clocks in at less than 40 bucks.

What To Look for in a Brightening Vitamin C Serum

An Opaque Bottle

Vitamin C is inherently unstable, quickly broken down when exposed to light and/or oxygen. For that reason, Cheung suggests looking for products that come housed in opaque bottles (bonus points if they 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 bang for your buck, Cheung suggests looking for this type of vitamin C, the most potent and active version. That being said, it is the priciest and comes with the highest likelihood for irritation. Other less intense versions include sodium ascorbyl phosphate and magnesium ascorbyl phosphate.

Other Antioxidants

Vitamin C works synergistically, meaning it plays very nicely, with other antioxidants, such as vitamin E and ferulic acid, says Cheung.

FAQ

• What does vitamin C serum do?

  According to 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 our skin more support and structure. Finally, vitamin C is a brightening agent, so a serum that features it can work to even skin tone and fade hyperpigmentation.

• When should you apply vitamin C serums?

  Many people have strong preferences on when to apply vitamin C serums, debating whether it's better to use the ingredient to protect skin during the day or replenish it at night. Herrmann says you can choose which time of day to apply, but notes that consistency is key.

• How should you apply vitamin C serums?

  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 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.
