If you were to hand out skincare superlatives, antioxidant serums would win Most Popular, and for good reason. These concentrated formulas are just so freaking effective when it comes to maintaining a healthy complexion.

“Antioxidants help protect skin from oxidative damage due to free radicals formed through UV rays and pollution,” explains Howard Sobel, MD, a cosmetic dermatologist in New York and founder of Sobel Skin. “Plus, antioxidants can improve dull-looking skin and work with SPF to boost sun protection.”

It’s crucial to apply an antioxidant serum during the day and in the evening. “In the morning, layer it under a moisturizer with a sun protection factor of at least 30,” says Dr. Sobel. While you snooze, your body naturally builds up a storage of antioxidants, so using a serum at night can help ensure that your skin has enough ready to go in the morning, he adds.
