Vitamin C is a superstar ingredient when it comes to managing a myriad of skin issues, from large pores and hyperpigmentation to loss of collagen and dullness. This serum has the brightening agent in spades. A helpful tip: You can tell a good vitamin C serum from a bad one by the jar it's stored in. Vitamin C is incredibly unstable and can break down when exposed to light; whenever you're searching for a product with this ingredient, search for options, like this one, that are housed in dark jars (they won't be compromised by exposure to sunlight).
