Skincare experts explain why you need to add this ingredient to your beauty routine.

Finding the best beauty products has never been easier thanks to Pia’s Picks, our weekly curated list. As the senior beauty editor at HelloGiggles, I test and examine the latest skincare, makeup, hair, and nail products so I can confidently recommend the best ones to you.

By this point we all know that vitamin C is the powerhouse ingredient behind the best brightening skincare ingredients. It’s found in our favorite face oils, serums, and moisturizers, and it’s deemed by dermatologists to be the best ingredient to get brighter, glowier skin.

However, there’s a plethora of skincare products to choose from, and it can be overwhelming to evaluate which ones work best. Who among us hasn’t spent hours in a beauty shop unsure of which vitamin C serum to invest in? To get past the confusion and uncertainty, we tapped several dermatologists and skin care experts to find out all there is to know about vitamin C—and learn about the best skincare products to help us get our glow on.

What is vitamin C?

Vitamin C is a natural antioxidant found in the skin, and it neutralizes free radicals on the skin. Ashley Magovern, M.D., a board-certified dermatologist and the medical director for Dermstore, explains that it’s important to protect the skin from free radicals since they can damage the cells’ DNA. “This can lead to premature aging and skin cancer,” she explains.

What is a vitamin C serum?

Studies show that when applied topically, vitamin C reduces hyperpigmentation and is anti-aging—and a serum is just one type of vehicle to apply topical vitamin C. “Serums are popular because they’re thin and feel silky going on—I like them because it’s easy to layer other products on them,” says Dr. Magovern.

How does vitamin C serum work?

“The antioxidant properties of vitamin C means it scavenges free radicals caused by UV exposure that would otherwise cause sun damage,” explains Sarah Biggers-Stewart, CLOVE + HALLOW founder and CEO. “It’s also acidic and reduces melanin production in the skin, which in turn triggers collagen production and reduces hyperpigmentation or other damaged skin spots.”

What are the benefits of a vitamin C serum?

It’s all about the collagen. According to Dr. Magovern, vitamin C “boosts collagen production and reverses cell damage, which helps keep the skin firmer and looking younger, and even helps fade and prevent brown spots or pigmentation.” The best part? A vitamin C serum doesn’t need to be applied every day. As Dr. Magovern explains,

“The receptors get saturated, so unless you love the way it feels on your skin, you could probably make it last a little longer by using it every other day.”

With that in mind, vitamin C serums can be used every 48 to 72 hours since, as Dr. Magovern notes, its “effectiveness may reach a plateau with daily use, so you may be able to stretch your dollar.” We’re all for spending a little less.

Now that you’ve got the scoop on vitamin C serums, here are the 11 best ones.
