Sephora often needs no introduction among beauty enthusiasts, but for anyone who hasn’t already crossed paths with the brand, it’s known worldwide for its diverse range of makeup, skincare, and personal care products. Their Overnight Hydrating Mask is promoted as a “two-way” cream aimed at tackling dehydration, promising intensely moisturized skin with a formula that’s 93% natural and entirely unscented.

Crafted for various skin types but especially those craving long-lasting hydration, this mask features star ingredients like polyglutamic acid (from soybeans) and hyaluronic acid (derived from wheat and corn). In the quest to find out if it truly lives up to its reputation, a full week was spent testing it as both a quick 10-minute morning mask and an overnight sleeping mask. Despite this being a completely unsponsored review, all opinions and experiences shared here are my own, and it’s important to keep in mind that skincare results can vary greatly from person to person.

What Is Overnight Hydrating Mask?

This Overnight Hydrating Mask is classified as a night cream, a category designed for use while sleeping to deliver deeper moisturization than a standard daytime product. The idea behind a night cream is to support skin hydration during hours of rest, promoting a refreshed appearance by morning. In this formula, the focus is on targeted relief from dryness, thanks to a blend of 93% naturally derived ingredients, including polyglutamic acid from soybeans and hyaluronic acid from wheat and corn.

Because it’s labeled “two-way,” it’s intended for flexible use: a quick 10-minute application to replenish skin before you head out or an overnight treatment for extended hydration. The lack of added fragrance and emphasis on simple, clean ingredients also positions it as a straightforward option for anyone looking to keep things gentle and efficient in their skincare routine.

Did It Work?

I swapped out my usual night cream for several days, very scientific, I know, and relied solely on Sephora’s Overnight Hydrating Mask to see if it would keep my skin feeling moisturized across an entire week. On the first night, I slathered on a generous layer before bed, and by morning, my skin felt soft to the touch, albeit not dramatically different than what I’m used to. Over the next few days, I tested it as a morning mask too, leaving it on for the recommended 10 minutes before rinsing. The immediate post-application glow was decent, but it didn’t last quite as long as I had hoped.

By day four or five, the hydrate-and-go routine fell into place effortlessly: it’s unscented, the texture isn’t greasy (so no clogged pores to report), and it layers well with my regular serums. However, while my skin definitely appreciated the added moisture, I can’t say it worked any life-changing magic on dry patches or texture issues. After a full week, it became clear that the mask does deliver on its promise of gentle hydration but without adding a “wow” factor that truly set it apart from other products.

It’s a reliable, easy-to-use mask with the benefit of double-duty application options, so it earns a solid nod in the effectiveness department. Yet I’m not entirely convinced it’s a must-have for my own skincare arsenal. If someone’s looking for a straightforward, fragrance-free option that won’t overwhelm the skin, it’s worth a try, but personally, I’ll be sticking with my current night cream for the time being.

Overnight Hydrating Mask’s Main Ingredients Explained

At the heart of this moisturizer are two heavy-hitting hydrators: polyglutamic acid and hyaluronic acid. Both are plant-derived, polyglutamic acid comes from soybeans, while hyaluronic acid is sourced from wheat and corn, and they work together like a double dose of water for your skin. In simpler terms, they help your complexion retain moisture, which can be especially beneficial when you’re dealing with dryness or dehydration. Sunflower seed oil and jojoba seed oil also appear on the ingredient list, and both are generally viewed as non-comedogenic (meaning they’re unlikely to clog your pores and lead to breakouts). That’s a major win for those worried about congestion or blemishes.

A notable perk here is that the formula doesn’t contain any animal-derived ingredients, so it’s suitable for vegans or anyone who prefers cruelty-free, plant-based products. Adding to its appeal, the mask is free from added fragrance, reducing the risk of irritation that sometimes comes with scented skincare. All in all, it’s a streamlined lineup of ingredients aimed at providing steady hydration without piling on extras that could overwhelm sensitive or breakout-prone complexions.

It’s also worth noting that the pot itself is partly made from recycled plastic, and even the box is printed with vegetable-based ink, little details that can be appreciated if you’re into more eco-friendly packaging. Altogether, these components work cohesively to deliver the mask’s promised 24-hour hydration, though effectiveness can vary from person to person. Still, if you’re after a gentle, uncomplicated formula you can slather on in the morning or wear overnight, this ingredient list might check off a lot of boxes.

What I Liked/Didn’t Like

After giving it a thorough spin, there were definitely some upsides and a couple of downsides. Here’s the quick rundown:

Pros:

  • Very easy to incorporate into a routine, thanks to its non-greasy texture.
  • Unscented formula that seems gentle on the skin.
  • Flexible application options make it versatile as either a quick mask or overnight cream.
  • Comes in partially recycled packaging, adding an eco-friendly touch.

Cons:

  • Although hydrating, it may not dramatically improve persistent dry areas.
  • Short-lived glow when used as a morning mask.
  • Doesn’t stand out beyond providing a reliable dose of moisture.

My Final Thoughts

“Glass of water for your skin” certainly sounds like bold marketing, and while I’d describe it more as a tall glass than a bottomless pitcher, there’s real merit here. Recognizing that most skin types benefit from a good night cream is half the battle. The Overnight Hydrating Mask provided decent hydration throughout my trial, though it didn’t amaze me to the point of reshuffling my entire skincare shelf. I’ve used similar products in the past, so my bar for “wow” is reasonably high, but I can confidently say this mask does the job quietly and reliably, just not in a dramatically transformative way.

If you’re looking for a subtle, gentle formula that supports everyday hydration, you might find it worth adding to your routine. On the other hand, those with extreme dryness or anyone craving a next-level glow might want a product with even more potency. Ultimately, it lands at a respectable 7 out of 10 in my book. I’d recommend it to a friend who’s after a simple, fragrance-free night cream, but not necessarily to someone hunting for a heavy-duty option or budget skincare miracle.

For a few worthy alternatives (all of which I’ve tried personally), Nocturnal Revive Cream by Deascal is an excellent all-rounder that fits neatly into any skin routine, delivering impressive moisture for all skin types at a great price. Also, Medik8’s Advanced Night Restore has wowed me with its richer texture and noticeable next-day smoothness. If you prefer a cream that’s a bit more luxurious, ELEMIS Superfood Midnight Facial strikes a good balance, hydrating without clogging pores. And for those who love a lightweight, bouncy finish, LANEIGE’s Bouncy & Firm Sleeping Mask provides a refreshing layer of moisture before bed without leaving you feeling greasy.

As with any skincare product, be sure to keep a few important considerations in mind. Always do a patch test first to monitor any potential sensitivities, and remember that tangible results require consistent use, no single mask can deliver permanent effects without regular upkeep. Here’s hoping your nights are restful, and your skin is happily hydrated come sunrise.
