This Holy Grail Helps With Crepey Skin & Dark Spots — Here's How To Use It

There are so many reasons to love vitamin C (both in the health and beauty space), and we could go on and on about its laundry list of skin care perks (in fact, we already have; check them out here).

Collagen literally holds your skin together—it's what gives your skin that youthful, plump bounce, and it diminishes over time for a variety of factors. As such, experts recommend supporting collagen production while you age, through topicals and supplements. 

That's because vitamin C can actually promote fibroblast production1 and regulate collagen synthesis2 (aka, the pathway in which collagen is made). "Vitamin C is a key cofactor in the synthesis of collagen and elastin, [which helps] give your skin that plump and youthful appearance," Keira Barr, M.D., dual board-certified dermatologist, told us about vitamin c in collagen supplements.

When someone mentions vitamin C, the phrase "glowing skin" tends to follow—for good reason: While antioxidants at large can manage UV damage (the primary cause of discoloration), vitamin C is the antioxidant for skin brightening—its glow-inducing abilities are well documented, as research shows using vitamin C topically can help diminish hyperpigmentation3, even skin tone4, and help reduce skin inflammation3.

Let's circle back to the vitamin's free-radical-fighting abilities: As you likely know, free radicals (triggered by UV damage and other environmental aggressors) can lead to oxidative stress and visible signs of aging: like crepey skin, fine lines, and other textural and pigmentation changes. Antioxidants—oh, hello vitamin C—can protect the skin against photoaging by both absorbing UV rays and preventing UV-induced free radical damage5.
