A New Way to Support Overnight Skin Hydration
Collagen has become a staple in many beauty routines, from powders and capsules to creams and serums.
Night Renew by Dagsmejan introduces a new approach to overnight skin hydration: collagen-infused sleepwear designed to support your skin while you sleep.
Made with NATTCOLLAGEN™ technology Night Renew combines breathable eucalyptus-based fibres with marine collagen peptides permanently embedded into the yarn before the fabric is even knitted.
While collagen supplements support the body from within, Night Renew works externally — directly where your skin meets fabric for seven to nine hours every night.
Clinically proven results after 4 weeks
- +40% skin hydration
- +12% smoother skin texture
- 12x more breathable than cotton
- 100% would recommend Night Renew
Night Renew is skincare you can sleep in.
How Collagen Supplements for Skin Work
Collagen is one of the body’s main structural proteins and plays a role in skin structure and elasticity.
Many collagen supplements for skin contain collagen peptides for skin, usually in the form of powders, capsules or drinks. Once ingested, these peptides are broken down into amino acids that the body can use in different physiological processes.
Many people use collagen supplements as part of a broader beauty or wellness routine focused on:
- Skin hydration
- Skin elasticity
- Collagen for dry skin
- Healthy ageing
- Hair and nail health
This internal approach can support skin health from within.
But it does not directly influence the environment your skin is exposed to overnight — including fabric friction, breathability, heat or moisture loss during sleep.
That is where Night Renew takes a different approach.
How Collagen Sleepwear Works
Night Renew supports the skin externally through breathable, collagen-infused fabric designed for overnight recovery.
The collection uses NATTCOLLAGEN™ technology, where marine collagen peptides are permanently embedded into eucalyptus-based fibres. Unlike topical coatings that can fade or wash away, the collagen peptides are integrated directly into the yarn structure before the fabric is knitted.
The result is breathable, ultra-soft sleepwear designed to support overnight skin comfort while remaining exceptionally gentle against the skin.
Night Renew combines:
- Breathable eucalyptus-based fibres
- Thermoregulating comfort
- Ultra-soft, low-friction fabric
- Collagen-infused yarns designed to support overnight skin hydration
Because sleepwear remains in direct contact with your skin for hours every night, the fabric itself becomes part of the overnight recovery environment.
Why Night Is the Right Moment for Skin Hydration
Nighttime is one of the body’s most important recovery periods — including for the skin.
During sleep, the skin is exposed to heat, friction, dry air and changing moisture levels. Research shows that the skin barrier can lose more moisture overnight, particularly in dry or overheated sleep environments.
At the same time, sleep quality plays an important role in the body’s natural overnight recovery processes.
That means overnight skin hydration is influenced not only by skincare products or supplements, but also by what touches your skin while you sleep.
A breathable, low-friction fabric can help create a more comfortable skin-to-fabric environment overnight.
The Proof Behind Night Renew
Night Renew was independently tested in a four-week clinical application study conducted under dermatological supervision.
Participants wore the Night Renew long sleeve top and sleep mask every night while skin hydration and smoothness were measured before and after the study.

Expert perspective:
“Nighttime is when our skin’s natural regeneration processes are most active, making it the ideal moment to support hydration and renewal.”

Collagen Supplements vs Collagen Sleepwear
Collagen supplements and collagen sleepwear support skin hydration in different ways.
Collagen supplements are taken orally and support the body from within as part of a nutrition or wellness routine.
Night Renew takes an external approach through breathable, collagen-infused fabric designed to stay in direct contact with the skin throughout the night.
While supplements do not influence fabric friction, breathability or the sleep environment itself, Night Renew was specifically designed to support overnight skin comfort through thermoregulating, ultra-soft sleepwear engineered for overnight recovery.
The two approaches are not mutually exclusive. Rather, Night Renew introduces a new way to support overnight skin hydration — externally, during sleep.
A New Step in the Nighttime Skincare Routine
Most nighttime skincare routines end with a cream, serum or supplement.
But your skin remains in contact with fabric for seven to nine hours every night.
That makes sleepwear part of the overnight skin environment — and an opportunity to rethink how overnight skin hydration is supported during sleep.
Night Renew brings together Swiss sleep innovation, breathable eucalyptus-based fibres and NATTCOLLAGEN™ technology to create a new kind of collagen skincare at night.
Because beauty sleep should do more than simply feel comfortable.
