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

Once your skin has acclimated to a vitamin C concentration between seven percent and 15 percent, you can finally graduate to a higher potency for even more results. One of the most potent on the market is a new collaboration between Soko Glam and Korean beauty brand CosRx.

Together, they created a powerful 20.5 percent concentration vitamin C serum they've appropriately dubbed Triple C Lightning Liquid ($27). It's combined with 72 percent chokeberry, which helps to stabilize the vitamin C while hydrating and smoothing, as well as hyaluronic acid to hydrate and licorice root extract to soothe.
