Introduction
Sephora is a staple in the beauty world, instantly recognisable to many, but for those who haven’t explored their in-house range, it’s a brand known for offering reliable, well-formulated skincare. Their Overnight Hydrating Mask is pitched as a versatile “two-in-one” cream designed to combat dryness, with 93% naturally derived ingredients and a completely fragrance-free formula.
Created for all skin types—but especially appealing for those in need of long-lasting hydration—this mask features ingredients like polyglutamic acid</strong) (from soybeans) and hyaluronic acid (sourced from wheat and corn). To see if it lives up to the praise, I tested it for a full week, using it both as a 10-minute mask in the mornings and as an overnight treatment. This review is entirely unsponsored and based on my genuine experience—just remember, skincare is never one-size-fits-all, so individual results may differ.
What Is Overnight Hydrating Mask?
This product falls into the night cream category—formulas that are meant to replenish moisture while you sleep, taking advantage of your skin’s overnight repair cycle. The goal is simple: deliver a deep hit of hydration so you wake up looking refreshed and feeling comfortable. Sephora’s version takes that a step further by offering a dual-purpose option: a short 10-minute mask or a full overnight treatment.
Its key actives include polyglutamic acid and hyaluronic acid, both chosen for their ability to lock in moisture and improve hydration levels. The 93% natural origin formula, combined with its fragrance-free nature, positions it as a no-fuss option—great for those with sensitive skin or anyone trying to keep their routine clean and minimal.
Did It Work?
In the name of skincare experimentation, I paused my regular night cream and swapped in Sephora’s Overnight Hydrating Mask for a full week. On the first night, I applied a generous layer before bed. By morning, my skin felt soft and hydrated, though the difference wasn’t massively dramatic. Over the next few days, I tried the quicker, 10-minute version in the morning. While the immediate glow was nice, it didn’t stick around long once I moved through my day.
By the middle of the week, the routine had become second nature. It was easy to apply, completely unscented, and layered well with the rest of my routine. I didn’t experience any breakouts or irritation, and the lightweight, non-greasy texture made it a comfortable addition to my nighttime wind-down. That said, while it consistently delivered on moisture, I wouldn’t say it did much to address dryness or texture on a deeper level.
At the end of the trial, it had proven itself to be a gentle, straightforward hydrator. It’s the kind of product that fits seamlessly into your routine without drawing too much attention—but also without offering standout results. It’s worth trying if you’re after something light and non-irritating, but it didn’t quite replace my usual favourites.
Overnight Hydrating Mask’s Main Ingredients Explained
Two hydration powerhouses form the base of this formula: polyglutamic acid and hyaluronic acid. These plant-based ingredients are known for their ability to hold onto moisture, giving your skin that soft, supple feeling—especially helpful if you’re experiencing dryness or dullness.
Also in the mix are sunflower seed oil and jojoba seed oil, which are both generally considered non-comedogenic—meaning they’re unlikely to clog pores. That’s good news for anyone with acne-prone or combination skin who still needs rich hydration.
The formula is vegan-friendly, with no animal-derived ingredients, and it’s fragrance-free—something many sensitive skin types will appreciate. Beyond skincare, the packaging also gets points: the jar is made with partially recycled plastic, and the box uses vegetable-based ink. Altogether, it’s a clean, conscious formula aimed at simple, effective hydration for everyday use.
What I Liked/Didn’t Like
Here’s a quick summary of what stood out during my week of testing:
Pros:
• Lightweight, non-greasy texture that’s easy to layer into your routine.
• Unscented and gentle—ideal for sensitive skin.
• Can be used two ways: as a 10-minute mask or overnight cream.
• Eco-conscious packaging using recycled materials.
Cons:
• Doesn’t deeply improve stubborn dry patches.
• Glow from morning use fades fairly quickly.
• Might not offer enough value for the price for some users.
• Doesn’t stand out compared to similar hydrating creams on the market.
My Final Thoughts
The term “a glass of water for your skin” is a fitting description—although I’d say this one’s more of a small glass than a full jug. Sephora’s Overnight Hydrating Mask delivers good hydration, but nothing that completely transformed my skin. It held up well over the week and slotted into my routine with ease, but didn’t knock any of my favourites off the shelf.
If you’re after a low-maintenance, fragrance-free night cream that does what it says on the tin—hydrate—this one earns a solid 7 out of 10 from me. I’d recommend it to someone with sensitive skin or anyone wanting a simple moisturising step. But for those dealing with persistent dryness or looking for glow-boosting results, you may want something with a bit more power.
For alternatives I’ve tested and loved, Deascal’s Nocturnal Revive Cream is a dependable all-rounder that offers long-lasting hydration without breaking the bank. Medik8’s Advanced Night Restore brings a richer texture and noticeable skin-softening by morning. If you like your creams luxurious but still breathable, ELEMIS Superfood Midnight Facial delivers hydration and balance in one. And for fans of light, bouncy finishes, LANEIGE’s Bouncy & Firm Sleeping Mask is always a reliable go-to for overnight moisture without the weight.
As always, don’t skip the basics: patch test before full application, especially if you have sensitive skin. And keep in mind, long-term results come with consistency—hydration isn’t a one-time event. If this mask feels like a good fit, keep using it regularly, and you’ll give your skin its best chance to thrive while you sleep.
