What is ESPA Overnight Hydration Therapy?
ESPA Overnight Hydration Therapy is a 55ml overnight treatment mask designed to hydrate, smooth and replenish the skin while you sleep.
Rather than being a traditional thick night cream, it is intended to be used as an intensive treatment. You apply it to your face, neck and décolleté after cleansing and allow it to absorb before heading to bed. ESPA recommends warming a blueberry-sized amount between your fingertips, smoothing it over the skin and massaging until the formula turns white.
What makes it particularly interesting is that it combines skincare with ESPA's signature aromatherapy approach. The formula contains a blend of essential oils including Cedarwood, Ylang Ylang and Lavender, giving it that instantly recognisable spa-like aroma.
My ESPA Overnight Hydration Therapy reviewThe first thing you notice is the texture and application. This is definitely more of a treatment than a lightweight moisturiser, so I like using it as the final step in my evening skincare routine when my skin needs a little extra attention.
You massage it into the skin until the formula turns white, which is a slightly unusual but satisfying part of the application. Once absorbed, it leaves my skin feeling moisturised and comfortable rather than like I've simply applied a layer of heavy cream.
For me, the biggest difference is noticeable the following morning. My skin feels softer, more hydrated and generally looks fresher. It's particularly useful when my complexion is feeling dry or lacking that healthy-looking glow.
The hydration is really the star of the show here. ESPA says the treatment is designed to soften the feel of dry patches, improve the appearance of texture and leave skin looking fresher and more even. The brand's internal trial also reported that 96% of participants agreed their skin felt smoother and more hydrated after first use, although this was a 56-person internal user trial.
I also really enjoy the aromatherapy element. The Lavender, Ylang Ylang and Cedarwood blend gives the product a calming, luxurious scent that makes applying it before bed feel like part of a proper wind-down ritual rather than simply another skincare step.

How do you use ESPA Overnight Hydration Therapy?The beauty of this product is that you don't need to make your evening routine complicated.
After cleansing, apply a blueberry-sized amount to your face, neck and décolleté. Massage it in using gentle upward strokes until the formula turns white, then allow it to absorb before going to bed. Leave it on overnight and cleanse your skin as normal in the morning.
ESPA also suggests applying it over your favourite serum or facial oil if you want an even more nourishing treatment.
I would personally save this for evenings when my skin needs that extra hit of hydration rather than necessarily using it every night. It's the kind of product that feels particularly welcome when your skin has been exposed to cold weather, central heating, travel or anything else that leaves it feeling dry and depleted.
Who is ESPA Overnight Hydration Therapy suitable for?If your main concern is dry or dehydrated skin, this is the type of overnight treatment that makes a lot of sense.
It's also worth considering if your skin is looking dull, feels tight or simply needs some extra nourishment. ESPA states that the product is designed to leave skin feeling softer, smoother and more hydrated while improving the appearance of radiance and texture.
The aromatherapy element is another reason I think this works particularly well as a night-time product. It turns what could be a fairly ordinary moisturising step into more of a spa-at-home experience.
Is ESPA Overnight Hydration Therapy worth trying?For me, this is one of those products that makes sense when your skin needs serious hydration without making your routine complicated.
I like that it does more than simply act as another moisturiser. The combination of overnight hydration, smoothing ingredients and ESPA's aromatic blend makes it feel like a proper treatment, while the results are particularly noticeable in the morning when my skin feels softer and more comfortable.
It's also not just my experience. ESPA's own customer reviews include repeated comments about the product leaving skin feeling hydrated, soft and refreshed, while the current M&S listing has a 4.7/5 rating from 220 reviews.
One thing to bear in mind is that the richer treatment texture and aromatic essential oils won't necessarily be everyone's preference. Some customer reviews specifically mention the formula feeling sticky or heavy, while others love the texture and scent.
Final thoughts
ESPA Overnight Hydration Therapy is a lovely addition to an evening skincare routine when your complexion needs some extra TLC.
The combination of Hyaluronic Acid, Chicory Root, Vitamin C, Konjac Root and Crispus Algae focuses on hydration, smoothing and radiance, while the Lavender, Cedarwood and Ylang Ylang aroma gives it that unmistakable ESPA spa experience.
For me, the real appeal is waking up the next morning to skin that feels soft, comfortable, hydrated and refreshed. It's a simple overnight step, but one that makes my evening routine feel considerably more luxurious.
