8 Vitamin C-Infused Products That Will Actually Improve Your Skin

For a step above the 7.5 percent concentration — and for an antiaging boost — reach for Drunk Elephant C-Firma Day Serum ($80). This beauty-guru fave quickly brightens skin thanks to its antioxidant complex, which includes 15 percent vitamin C, one percent vitamin E, and ferulic acid (an antioxidant that helps stabilize vitamins C and E).

It also contains an antiaging ingredient called chronocyclin, which promotes cell turnover and mimics vitamin D skin benefits, as well as pumpkin ferment extract and pomegranate enzyme to slough off dead cells. Finally, C-Firma contains a hyaluronate crosspolymer for an instant dose of moisture that reduces the appearance of fine lines.
