The Best Vitamin C Serums Recommended by Dermatologists – 2023

There are a lot of serums out there, from eyelash serum to hyaluronic acid serum to anti-aging face serum. If you only have room in your makeup bag for one, experts say to go with a vitamin C serum. “Vitamin C is a powerful antioxidant that fights fine lines by stimulating collagen, brightens your complexion by blocking excess pigment creation, and protects your skin from damaging free radicals and other environmental stressors,” says Michelle Henry, MD, board-certified dermatologist at Skin & Aesthetic Surgery of Manhattan. “As we age, though, the skin’s natural levels of antioxidant vitamin C decrease, which is why it’s so important to add it to your skincare routine.” The one downside? Compared to most products, it often costs more per ounce.

To make sure you get the best return on your investment, here are a few things to keep in mind: Skip creams spiked with vitamin C and instead choose a serum, which is more effective at penetrating the skin barrier, says Brooke Jackson, MD, a board-certified dermatologist at Skin Wellness Dermatology Associates. Additionally, there are several forms of vitamin C—and not all are created equal, says Henry. Check the label for L-ascorbic acid, which is considered to be the vitamin C that’s best for skin. (Even better: if it contains 15 to 20 percent L-ascorbic acid, which is the most effective.) “Vitamin C is notoriously unstable—especially when it’s exposed to air and light,” says Jackson. “So it’s best to pick a formula that comes in an airtight pump or opaque bottle, and keep it away from direct sunlight.”

So, which ones are worth it? Dermatologists say these face-brightening-and-tightening formulas—suitable for a wide range of skin concerns, including acne, hyperpigmentation, oiliness, dryness, and sensitivity—are the best vitamin C serums money can buy.
