Have you heard the Korean term "chok chok" before? It translates to bouncy, glowy skin -- aka a cornerstone of every great K-beauty routine.

Two of your favorite moisturizing superstars join forces in the Ulta Dewdrench Replenishing Essence, $19.50 -- and honestly, what's not to love? Plus, at just shy of $20, it's fairly affordable, and you'll love how soft it makes your skin.

If there was a class superlative for prettiest formula, it would most certainly go to the H2O+ Oasis Hydrating Booster. And it's got more than just looks going for it: This lightweight hyaluronic acid serum adds a considerable amount of non-greasy hydration, and the pretty blue beads suspended in the formula are packed with glow-boosting vitamins A and E.

At $240, MDNA Skin The Serum doesn't exactly come cheap -- though would you expect any less from Madonna? If you've got the spare cash, you should consider shelling it out, as it combines the moisturizing power of three forms of hyaluronic acid, along with apple stem cell, resveratrol and vitamins to basically give you the best skin of your life. Cue "Like a Virgin!"
