Sometimes, no amount of hydrating serums or heavy moisturizers can do the trick—our skin is just too thirsty. Especially now, as the air turns crisp and summer melts into fall, hydration isn’t as easy as it once was. That dry air can wreak havoc on our fragile faces. Which is why going to bed in an overnight hydrating mask a few times a week can be a dream come true for parched skin.

“Overnight masks are designed to help ingredients penetrate deeper into the skin as you sleep,” explains Michael Horn, MD, a board-certified plastic surgeon at Lake Shore Plastic Surgery in Chicago. “An overnight mask serves as a barrier and sealant. A light coating can prevent dirt and dust from closing in on pores while locking in other active products, letting all the good work more effectively without evaporating.”

As it happens, bedtime is one of the best times to rehydrate. Dr. Horn says that when you’re in a deep sleep (usually between 10 P.M. and 2 A.M.), the skin’s metabolism increases, escalating cell turnover and renewal. “Using an overnight mask gives the renewal process an extra push. Overnight masks also lock in moisture by sitting on top of your skin rather than getting immediately absorbed. Skin can recover moisture while excess water is processed for removal,” he says.

As you can imagine, not all overnight hydrating masks are created equal. Sussing out which ones are going to quench your thirst as opposed to the ones that will leave you thirsty for more is easy—all you have to do is keep reading.

What to look for (and what to avoid)

The big ingredient effective masks have are the occlusives, or fatty acids, which are what draw moisture to the skin and actually keep it in there. Think: jojoba oil, Argan oil, vitamin E—anything that keeps your face plump and un-parched.

Dermatologist Rachel Nazarian, MD, FAAD, recommends also keeping an eye out for hydrating and anti-inflammatory ingredients, like niacinamide and, of course, hyaluronic acid. “I love masks with ceramides, peptides, hydrating oils and fatty acids, such as shea butter, or olive extract,” she says. “Occlusion, or covering of the ingredients with an emollient or sheet, can enhance penetration of the ingredients, making them more potent and effective.”

As for what to avoid, steer clear from anything that dries out your skin—this will just negate the purpose of a hydrating mask in the first place. It seems obvious, but sometimes dehydrating ingredients can be sneaky. Both experts say ingredients like alcohol, fragrance, clay, or activated charcoal can cause the opposite effect, and leave you more parched than quenched.

How to use overnight hydrating masks

Most obviously, overnight masks are meant to be used overnight, putting in the work while you snooze. But using them too often can leave your skin oily and greasy, while not using them enough won’t help, either. How often should you be using your overnight mask? It depends—on the mask type, skin type, and season. For most masks, 1-2 times a week should suffice.

“With colder seasons—and when the temperature drops and the air becomes dry and arid—use can be increased to 2-3 times weekly with many of the gentle, hydrating masks,” Dr. Nazarian says. “Dry and sensitive skin types may want to consider more frequent use during the fall and winter to improve their skin barrier and minimize loss of moisture into the environment overnight. This can keep their skin healthy and prevent some of the classic irritation that happens during the colder months.”

And of course, do your homework. Dr. Horn says even though most overnight masks are formulated on the gentler side, some aren’t made to stay on your skin for too long. Others might interfere with other products you’re using: “If your nighttime routine consists of retinol or any acids, be mindful not to use a mask with the same ingredients, as too much of any ingredient can irritate the skin.If your skin is super sensitive, ask your dermatologist for a direct recommendation.”
