Description

As a young girl who loved pirates, I knew vitamin C treated and prevented scurvy…and that’s about it. But as I got older, wiser and more interested in health and skin support, vitamin C began to show its true colors. From its role in collagen production, brightening skin and targeting dark spots, as well as improving skin texture, this might just be one of the most handy skincare products you can invest in.

Vitamin C serums have become a skincare staple for good reason thanks to its versatility and variety of de-aging capabilities. But just like with any skincare product, there’s no one-size-fits-all miracle worker, so it’s important to understand how vitamin C serums work, who they're suited for and a few of our top product picks.

Why Use Vitamin C Serums?

There’s a number of benefits to using vitamin C, and topical vitamin C is a favorite ingredient in many skincare products today. When used as a moisturizer or serum, vitamin C is more easily absorbed directly into the topmost layers of the skin.

The main reason vitamin C is so widely used? It’s anti-aging properties. From wrinkles to dark spots, with long-term use vitamin C can reverse certain signs of aging in the face and neck.

  1. Sun protection: According to some studies, vitamin C and E are potent antioxidants that can be additional protection against UVA and UVB damage (sunburn cell formation) when used in combination with a broad spectrum sunscreen.
  2. Collagen production: Collagen is a protein in your skin that helps it maintain structure and firmness, but will gradually reduce as you age. Vitamin C is considered vital to the synthesis of collagen – without vitamin C, the production of collagen will be slowed, causing weakened skin barrier and leading to signs of aging.
  3. Improved skin texture: According to one study, daily use of vitamin C for at least three months helped improve the appearance of fine and coarse wrinkles of the face and neck.
  4. Brightening complexion and reducing dark spots: Vitamin C inhibits melanin production. Excess melanin can lead to hyperpigmentation, age spots, sun spots and more.
  5. Even skin tone: Similar to melanin production, vitamin C is touted to reduce acne spots and scars due to its anti-inflammatory properties, as well as assist in controlling sebum production.

Best Season To Use Vitamin C Serums

The short answer: You can use vitamin C serums year round, and it has been recommended by many sources as a “summer essential” in your skincare routine. There are some application considerations between summer and winter, however, that can help take your results to the next level.

Tips for summer use:

  1. Considerations: Vitamin C serums may increase sensitivity to sunlight. You should always use at least SPF 30+ during the day. Be sure to check out our Best Sunscreen top picks for our sunscreen recommendations.
  2. Application times: In the morning apply after cleansing but before moisturizer and sunscreen. At night it can be used after cleansing and toning.
  3. Vitamin C concentration levels: The ingredient name for vitamin C is ascorbic acid, also known as L-ascorbic acid. The most effective vitamin C concentration levels fall between 10-20%. Using anything over 20% may cause skin irritation, breakouts, skin purging and itchiness.

Tips for winter use:

  1. Dry skin hydration: Layer your vitamin C serums with heavier moisturizers, especially at night. During the day, combine it with sunscreen to protect against further skin damage and irritation.
  2. Application times: Can be used both morning and evening following cleansing and moisturizing schedules, especially during lower UV months.
  3. When to use higher concentrations: If your skin is tolerant of higher concentration skincare products, you may find you’re able to use stronger formulations (15-20%+) when sun exposure is limited during the winter months.

How To Choose The Right Vitamin C Serum Based On Skin Type

Before you rush to buy a vitamin C serum, you’ll want to take stock of your skin type and consider ingredient lists before you choose. When starting a new skincare regimen, be sure to talk to your dermatologist or other specialist to make sure a vitamin C serum is right for you.

Normal to Oily Skin: Choose L-ascorbic acid (10-20% concentration)

L-ascorbic acid is the most common – and potent – form of vitamin C. If you’re not prone to skin reactivity, this is going to be the most ideal option.

Sensitive Or Dry Skin: Choose a mild formula and low concentration

If you have sensitive or dry skin, you’re going to want to use caution when it comes to ingredient lists and concentration levels to avoid irritation, skin purging, redness or itchiness. Using L-ascorbic acid on sensitive skin, especially at higher concentration levels, can cause further redness and dryness.

Start with lower concentrations ( between 5-10%), and get a vitamin C serum that also contains other soothing ingredients like niacinamide or hyaluronic acid.

For a gentler formula, you may want to consider these ingredient options instead of L-ascorbic acid:

  1. Sodium Ascorbyl Phosphate ( SAP ): Less likely to cause irritation in sensitive or acne-prone skin.
  2. Magnesium Ascorbyl Phosphate (MAP): Another effective form of vitamin C, it’s an ideal option for dry or sensitive skin, and one source does recommend it if you’re after skin brightening. It’s more stable than some of the other ingredients, though data suggests it may not be absorbed as well compared to ascorbic acid.
  3. Tetrahexyldecyl Ascorbate: An oil-soluble form of vitamin C, it’s stable and easy to use in serums, and initial data suggests it does provide antioxidant protection against UV, increases collagen synthesis and has skin brightening effects. It’s a promising ingredient option but not well-proven yet, according to Incidecoder.
  4. Ascorbyl Palmitate: Not as potent as other ingredients, but can be used on more skin types (including sensitive skin), however, according to Incidecoder, it’s one of the least favored vitamin C ingredient options – lower stability, does not penetrate as easily, and it has questionable antioxidant properties.

If you have dry skin, you’ll want to make sure you’re properly hydrating and moisturizing your skin when using vitamin C serums, as it can cause further dryness or irritation.

If you have extremely sensitive or reactive skin, you may want to skip using a vitamin C serum entirely.

Acne-Prone Skin: May cause initial purging

Vitamin C serums are considered helpful due to its anti-inflammatory properties that are designed to help reduce redness and swelling from acne. It also claims to help improve the appearance of acne scars by promoting increased collagen production and helping to heal wounds faster.

If you have sensitive or acne-prone skin, we recommend you speak with your dermatologist or doctor before adding a vitamin C serum to your skincare routine.

How We Made Our Decision

Firsthand testing

I’ve personally tested a number of products on this list, noting what I experienced during my testing. My testing includes the La Roche-Posay Pure 12% Vitamin C Serum that I’m actively using right now, as well as the TrueSkin Vitamin C Serum and Yuzu Vitamin C Sleep Mask.

Functionality

Does it do what it’s designed to do? When pulling together our best-selling list of vitamin C serums, we measured it by a few different criteria, including: skin brightening, spot reduction, skin smoothing, hydrating and fewest reports of skin irritation. While not all products are created equal (and there are no popular skincare products on the market with zero skin reactions), we’re looking for the highest number of reviewers that note the product works for a variety of skin types.

Ingredient list

While products with L-ascorbic acid are considered king of vitamin C serums, we made sure to also include products that feature other premium ingredients, such as:

Vitamin C concentration levels

Not all vitamin C serums are created equal, and depending on your skin type and sensitivity, it will be critically important to pick the right concentration levels. If the concentration is too high, you risk skin irritation and breakouts. If concentration levels are too low, you may not see the results you are expecting. In our list, we included concentration levels starting at 12% up to 22% for a broad range of vitamin C serum effectiveness.

Price point

We did include one luxury pick (and at $185 per bottle, that’s quite a chunk of change), however the glowing reviews and product performance outweighed the price point. Other than the SkinCeutical vitamin C serum, we wanted to ensure there were price-friendly options starting at $20-25, up to slightly more costly at $40+.

Reviews

When not testing ourselves, we defer to the reviewers who use the product and provide helpful, comprehensive feedback. If a product has few or poor reviews, we make sure to include the complaints, and if the negative feedback outweighs the intended use, we will not include it in our list.
