The Masks: Origins By All Greens Foaming Deep Cleansing Mask, $36, followed by Cremorlab Herb Tea Blemish Minus Calming Mask, $6.

The Why: Oily skin needs hydration, too. In fact, drying out your skin can cause it to rebel and create even more oil. This masking duo is an exercise in balance. The deep cleansing mask uses a blend of kaolin clay, green tea and spirulina to detoxify and unclog pores; the sheet mask contains thermal water, chamomile and black herb tea extracts that soothe and hydrate skin.

The Masks: Blithe Energy Yellow Citrus & Honey Splash Mask, $45, in the morning. Too Cool For School Egg Cream Sheet Mask, $6, in the evening.

The Why: Splash masks are just one of the many new Korean beauty trends making their way into U.S. Sephoras. This particular one is meant to be splashed -- that's where the name comes from -- onto your face while you're in the shower. It gently exfoliates and contains a blend of brightening fruit extracts and hydrating honey, and you only have to leave it on for a minute to get results. The sheet mask uses a blend of egg white and egg yolk extracts to moisturize and brighten. It's great for a relaxing treatment before bed or pre-makeup prior to an event.

The Masks: First Aid Beauty 5 in 1 Bouncy Mask, $38, in the morning. Dr. Jart+ Pore Minimalist Black Charcoal Sheet Mask, $7.50, in the evening.

The Why: Masks that contain ingredients like charcoal, spearmint extract and rose can help minimize pores. The bouncy masks plumps skin by supporting collagen production, making pores look smaller. Before bed, use a pore-tightening mask like the Dr. Jart. Just remember: Any time you use a mask that detoxifies and purifies with ingredients like charcoal and clay, be sure to moisturize. (Otherwise, you won't get the radiant, luminous skin you want.)

The Masks: Dermovia Rejuvenation Collagen Face Mask, $15, followed by 111 Skin Bio Cellulose Facial Treatment Mask, $160 for four.

The Why: "It's very important to topically hydrate to plump up the skin to reduce the visibility of fine lines," says Cho. You want to choose masks that have firming, plumping and hydrating ingredients. The Dermovia mask contains collagen and hyaluronic acid and uses special gauze technology to act like a temporary facelift. Follow with a superhydrating mask to make skin look dewy and fresh.
