Dagsmejan Night Renew Review: The Sleepwear Designed to Hydrate Your Skin Overnight
AD - GIFTED | What if your pyjamas could do more than simply keep you comfortable while you sleep?
We usually think of skincare as something that happens before bed: cleanser, serum, moisturiser, sleep oils, and perhaps a nourishing night cream. But Swiss sleepwear brand Dagsmejan is taking a rather different approach with its Night Renew collection, incorporating skincare-inspired textile technology directly into the fabric.
The idea is intriguing. Rather than applying another product to your skin, Night Renew uses NATTCOLLAGEN™ Technology, which incorporates marine collagen peptides into the fibres of the sleepwear. According to Dagsmejan, the technology is designed to create a moisture-balancing microclimate against the skin, helping support overnight hydration and smoother-looking skin. So, is collagen-infused sleepwear genuinely worth the investment, or is it simply another clever beauty trend?
What is Dagsmejan Night Renew?
Dagsmejan specialises in technical sleepwear designed around different aspects of sleep, from temperature regulation to comfort. Night Renew is its beauty-focused collection, combining breathable eucalyptus-derived fibres with marine collagen peptides. The concept is based on the fact that our skin undergoes important recovery processes while we sleep. Rather than treating sleepwear as an afterthought, Dagsmejan has designed Night Renew to work alongside that natural overnight process.
The standout feature is NATTCOLLAGEN™. Unlike a conventional fabric coating, Dagsmejan says the collagen peptides are permanently embedded into the fibre structure during production, before the yarn is knitted. This is important because the company says the peptides aren't simply sitting on the surface of the fabric where they could wash away after a few cycles. The result is sleepwear that looks relatively understated but has some surprisingly sophisticated technology built into it.
First impressions: Long Sleeve NATTCOLLAGEN™ SLEEP TECH
The Long Sleeve NATTCOLLAGEN™ SLEEP TECH in Navy Blue, is probably the piece that best demonstrates what makes Night Renew different from ordinary pyjamas. Visually, it is minimalist. There are no flashy logos or obvious signs that you're wearing technically engineered sleepwear. The navy blue colour (my personal favourite) gives it a classic appearance, making it feel more like a premium loungewear piece than a specialised skincare product.
The fabric is where the difference becomes much more apparent. Dagsmejan describes the material as soft, light and breathable, with eucalyptus fibres combined with NATTCOLLAGEN™ technology. The company's listed fabric composition for its Night Renew garments is 47.5% lyocell, 47.5% viscose and 5% elastane/Lycra. That combination makes sense for sleepwear. You want something that moves with you rather than something stiff or restrictive, particularly if you're someone who changes position frequently during the night.
The long sleeves are also useful from a skincare perspective because they maximise the amount of skin that comes into contact with the fabric. Rather than only having a collagen-infused top around your torso, the long-sleeve design extends that contact down the arms.

If the long-sleeve top is about maximum coverage, the NATTCOLLAGEN™ Sleep Tech Shorts provide the opposite approach: a lighter option for the lower half of the body. The shorts are described by Dagsmejan as soft and breathable, with a loose fit designed for comfortable overnight wear. The design includes a waistband and relatively short inseam, making them a practical choice if you don't like the feeling of full-length pyjama bottoms.
I particularly like the logic of pairing the long-sleeve top with shorts. It creates a balance between coverage and ventilation, giving you a better night's sleep, rather than turning the set into a heavy, enclosed pair of pyjamas. That could be especially appealing for people who find traditional pyjamas too warm.
Does collagen sleepwear actually hydrate your skin?
This is obviously the big question. Dagsmejan claims that Night Renew can deliver 40% higher skin hydration and 12% smoother skin texture after four weeks of use. Those numbers aren't simply presented as consumer testimonials: the company says the fabric was assessed in a controlled four-week study involving 20 men and women aged 35 and over, with measurements taken using corneometry and Antera 3D analysis.
This isn't the same thing as applying a conventional collagen skincare product directly to your face. The sleepwear is designed to influence the environment immediately around your skin, with the embedded peptides intended to help manage moisture at the skin-textile interface.
In other words, I'd view Night Renew as supportive skincare technology rather than a replacement for your normal skincare routine. If you already use moisturiser, serum or other products at night, there's no reason to abandon them simply because you're wearing collagen-infused pyjamas.
What about comfort?
For me, this is arguably just as important as the skincare technology. After all, you're buying sleepwear. If the fabric is uncomfortable, restrictive or too warm, the entire concept falls apart.
This is where Dagsmejan's use of eucalyptus-derived fibres becomes particularly interesting. The company says the fabric is designed to be breathable and temperature-regulating, helping create a comfortable sleeping environment. Independent testing by Empa, the Swiss Federal Laboratories for Materials Testing and Research, is also cited by Dagsmejan in support of the fabric's breathability.
The construction also includes flat ergonomic seams and strategically positioned seams intended to minimise friction during the night. The garments are tagless, with care information printed inside rather than using a conventional sewn-in label. These might sound like small details, but they're exactly the sort of details that can make a difference when you're wearing something for eight hours. A scratchy label or bulky seam might not bother you when you're standing around the house, but it can become surprisingly irritating when you're trying to sleep.
One of my favourite things about the Night Renew concept is that it doesn't look like futuristic sleepwear. The navy blue colour is particularly versatile. The long-sleeve top could easily be worn around the house in the evening, while the shorts give the set a relaxed, traditional pyjama feel.
That makes the premium price easier to justify if you're looking for something that serves multiple purposes. It's also worth noting that Dagsmejan positions the collection as sustainable and says its eucalyptus fibres come from sustainably managed forests and plantations, with different stages of production taking place across Europe.
Is it worth the price?
This is where things become more difficult. Night Renew is undoubtedly premium sleepwear. At the time of writing, Dagsmejan lists the Night Renew long sleeve at around £125/$145, while the shorts are similarly positioned at the premium end of the market. That's a significant amount to spend on pyjamas, but investing in your sleep could be a benefit in the long run.
You're not simply paying for cotton and stitching, though. The price reflects the technical fabric, collagen technology, specialist manufacturing and the brand's broader focus on sleep science. Whether it's worth it ultimately depends on what you're looking for. If you simply want inexpensive pyjamas, there are obviously far cheaper alternatives. But if you're already spending money on skincare, premium bedding, silk pillowcases or other products designed to improve your sleep and skin, Night Renew becomes a more interesting proposition.
Who should consider Dagsmejan Night Renew?
I'd say Night Renew is particularly appealing to several groups. First, people who struggle with dry skin overnight. The hydration-focused design makes the collection especially relevant if your skin tends to feel dry or tight in the morning. Second, people who dislike heavy or restrictive pyjamas. The lightweight, breathable fabric and loose-fitting shorts make the set appealing if comfort and temperature regulation are priorities.
Third, skincare enthusiasts. If you're interested in the latest beauty technology and like the idea of incorporating skincare principles into your everyday routine, this is certainly an unusual product to try. And finally, people who prioritise premium sleepwear. Even if you're sceptical about the skincare claims, the underlying focus on softness, breathability and low-friction construction makes Night Renew interesting as a piece of luxury sleepwear in its own right.
So, would I recommend the Dagsmejan Night Renew Long Sleeve and Shorts?
Yes — with one important qualification.
I wouldn't buy them expecting a miracle transformation overnight. The collagen technology is interesting, and Dagsmejan provides clinical and dermatological testing behind its hydration and skin-texture claims, but this should be viewed as an addition to a broader skincare and sleep routine rather than a replacement for one.
Where the collection really stands out is the combination of comfort, textile technology and skincare innovation. The Long Sleeve NATTCOLLAGEN™ SLEEP TECH in Navy Blue, offers excellent coverage and makes the most sense if you're interested in maximising contact between the fabric and your skin. The Shorts NATTCOLLAGEN™ SLEEP TECH in Navy Blue, complement it nicely, giving the set a lighter and more breathable feel while retaining the same collagen-infused fabric technology.
The biggest drawback is undoubtedly the price. These aren't everyday budget pyjamas, and you'll need to be comfortable paying a premium for technical sleepwear. But if you see sleep as part of your overall wellness and skincare routine, Night Renew is a genuinely innovative proposition.
Ultimately, Dagsmejan Night Renew is one of those products that sounds slightly strange until you understand the technology behind it. Collagen-infused pyjamas might initially seem like a gimmick, but the combination of embedded marine collagen peptides, breathable eucalyptus-derived fibres and dermatological testing makes the concept considerably more credible.
