It's rare that dermatologists make blanket recommendations about a single ingredient that everyone should be using, but in the case of vitamin C, it's the truth. It also could be why it's known as "the little black dress" of your beauty routine. The antioxidant serves up a two-for-one special by offering both short and long-term benefits for your skin.

Vitamin C Benefits

No matter your age, skin type, or complexion concerns, vitamin C should be a non-negotiable part of your morning regimen, in my opinion. It protects against environmental stressors, like pollution and UV damage, which cause oxidative stress that leads to signs of aging in your skin. In addition to fending off aggressors, it also helps to revive dullness, act as an anti-inflammatory, and even out the appearance of dark spots.

"It's a superstar skin-care ingredient and antioxidant," says Mona Gohara, MD, a board-certified dermatologist based in Connecticut. "I love to tell my patients to use it because it scavenges free radicals, resulting in brighter, better functioning skin."

It’s water-free so goes on smoothly, almost like a primer, and is great to use every morning as an environmental protectant. It’ll target uneven skin tone, dullness, and textural irregularities, too.

What to Look for in a Vitamin C Product

When searching for a product that you can be sure will do its job properly, derms suggest looking for products that pair vitamin C with a supplemental ingredient. Top contenders include vitamin E or ferulic acid, which will help amp up its efficacy and stabilize the molecules. Since vitamin C is sun sensitive (and can oxidize and become less effective with exposure), you should also opt for something in an opaque bottle that won't let light in.

How to use Vitamin C Serums

Vitamin C is most effective in the morning, so after you clean your face, add it to your a.m. routine before you start your day or leave the house, to protect your skin against UV rays and pollutants. And of course, top it off with sunscreen. If you use a retinol product at night, avoid using your vitamin C serum because the two don't work well together.—
