I know I’m late to the game, but for some reason, vitamin C only recently came on my radar. Sure, I’d heard about exfoliating, retinol, hyaluronic acid, etc.—and was incorporating them into my routine—but it’s only been in the past year or so that I’ve been fully turned on to the myriad vitamin C benefits. Turns out, I was missing out on a lot. And so now, with my interest fully piqued, I went to the experts to find and test out the best vitamin C serums. Spoiler: My skin couldn’t be happier.

The Expert
Did you know that vitamin C can be used every day? I hadn’t realized that it was gentle enough for daily use. However, if you also like to use retinol, feel free to alternate it by applying it every other day or conversely, use vitamin C in the morning and retinol at night. Luckily, most skin types tolerate this popular active ingredient well, but if you have extremely sensitive skin, you may want to skip it. And as always, be sure to talk with your dermatologist about vitamin c benefits for skin if you’re concerned.
We tapped Dr. Heather D. Rogers, dermatologist, dermatologic surgeon, and founder and CEO, Doctor Rogers RESTORE, to share some information about this wonder ingredient. Not only does she recommend daily vitamin C application to her patients, but she also uses a vitamin C serum every morning on clean, bare skin. It is the first topical she applies to the face, neck, and upper chest.

What is vitamin C?
Vitamin C is an antioxidant molecule that plays a vital role in our skin’s health by protecting it against free radicals caused by pollution and the sun’s radiation. It’s also an important ingredient for the production of collagen. When free radicals penetrate the skin, Dr. Rogers says they break down our collagen, contributing to sagging skin and wrinkles. Free radicals also stimulate the formation of brown spots and skin cancer.
An antioxidant is a molecule that can collect these free radicals and neutralize them before they damage our cells. This protection is different from the protection sunscreen provides and can and should be used together daily to slow the signs of aging and prevent the formation of skin cancers.
There are several kinds of vitamin C. The most common forms used in skincare products are:
- L-ascorbic acid
- ascorbyl palmitate
- magnesium ascorbyl phosphate
- ethyl ascorbic acid
- tetrahexyldecyl ascorbate.
Another great thing about vitamin C is that it’s the most well-studied antioxidant in topical skincare products. Dr. Rogers tells me multiple studies show that antioxidant serums with vitamin C that are stabilized with vitamin E protect your skin against photo-aging. Since the skin is very good at keeping things out, these antioxidants need to be in a well-formulated, easily absorbed vehicle to ensure these essential and expensive vitamins get deep enough into the skin to protect it. Formulation is key!
Who can use vitamin C?
Vitamin C is very safe for most people, but since it is an acid (ascorbic acid), it can irritate sensitive skin types. If you have very sensitive skin, you need to pick a lower percentage of vitamin C because your skin is too good at absorbing ingredients, which makes it more sensitive.
Most studies show benefits to the skin when using serums with 10% vitamin C. Higher percentages do not mean better results but can increase one’s risk of irritation.
How long does it take to see results?
Dr. Rogers points to several factors when it comes to seeing results. Generally, you may see improvement at two weeks, however most clinical studies measure results when using a product with vitamin C after 12 weeks. But that all depends on how damaged your skin is, how consistently you use the serum, how well formulated it is, and how young you are—since that dictates how quickly your skin turns over.
Vitamin C Application Tips
- Use it in the right order. If your vitamin C treatment is a serum, use it after cleansing or toning and before moisturizing. If it’s in your moisturizer, use it as your last step.
- Use vitamin C in the morning. You can totally use it at night, but you’ll get the most benefit from applying in the morning. It heals sun damage and protects against UV radiation, so you’ll have an extra layer of protection with a morning application.
- Pick the right concentration. If you have sensitive skin, look for something around 5%. If you have more extensive issues you can handle higher concentrations.
- More is not better. It’s just more expensive in the long run. A small amount goes a long way, but be sure to use it regularly for best results.
- If the product changes color, toss it! Oxidized vitamin C tends to lose its power. It can vary in color from colorless, to straw-colored to pale orange. If it’s turned brown it might be time to say goodbye.

Squalene, Coq10, and vitamins C and E harmonize to mimic and support the skin’s natural protection mechanisms.

This balancing serum is the perfect in-between step following your cleanser and before applying a moisturizer. As someone whose skin leans on the oilier side, I’ve noticed since using the serum that my skin’s oil production is kept in check. The result is a hydrated, glowy complexion that requires little makeup—perfect for summer. Hot tip: If you are using a tinted moisturizer this season, use the serum as a primer.

Best for Face and Body: Protéger Dermal Sérum
The skincare industry has been begging for a multi-use vitamin C serum—and Protéger delivers. “Featherweight” is an apt descriptor, because while other serums feel heavy and coat your complexion, Protéger’s Sérum goes on soft and smooth, offering an effective vitamin C-boosted formulation that shows up on the skin with just a light sheen. Glowy, gorgeous skin all over? Yes, please.
Protéger’s Dermal Sérum comes in two sizes. I personally have the larger bottle, and while the price is steep ($115 for 200 ml), I find that it’s justified by the fact that I can use this serum on both my body and face. Plus, a small pump goes a long way—it’s been months since I started using the serum and I’m still not even halfway through.
