The journey from fibre to sleep

Discover the journey behind Night Renew collection and the technology that transforms eucalyptus fibres and marine collagen peptides into skin-supporting sleepwear. Designed to help create a balanced overnight microclimate, Night Renew supports hydration, comfort, and smoother-looking skin by morning.

Research and development

Step 1: Understanding our physiological sleep needs

Research & Development

Nighttime is when the skin’s natural regeneration processes are most active. Night Renew was developed to support this renewal window through a combination of breathable eucalyptus fibres, thermoregulation, and NATTCOLLAGEN™ Technology — helping skin stay more comfortable, better hydrated, and supported while you sleep.

Step 2: Choosing the natural fibres

Breathable, skin-supporting fibres

Night Renew combines botanic eucalyptus fibres with naturally derived collagen peptides. Together, they help regulate temperature and moisture at the skin’s surface, supporting a more hydrating overnight microclimate and all-night comfort.

Breathable eucalyptus fibres

Wood and pulp used by Dagsmejan comes from natural forests and sustainably managed plantations. All fibers are certified with FSC® or PEFC™.

Eucalyptus needs 20 times less water than cotton and 5 times less high-quality farmland

Marine collagen peptides

Infused collagen peptides

Collagen peptides are embedded directly into the fibre to help capture moisture at the skin’s surface, supporting overnight hydration and a smoother, plumper feel by morning.

Step 3: Spinning the yarn

Collagen knitted into every fibre

The fibres are spun into a super-fine and super soft yarn according to the highest quality standards in Europe. The process is not only Oekotex 100 certified but also ISO certified (9001, 14001 and 50001)

Step 4: Dermatological testing

Clinically proven

Night Renew has been clinically and dermatologically tested for skin benefits and skin friendliness. In a 4-week study with participants aged 35+, nightly wear of the Night Renew long sleeve top and sleep mask led to +40% skin hydration and +12% smoother skin texture, while the products were also awarded the Dermatest 5-star seal for skin friendliness.

Participants also reported strong comfort and skin-feel benefits, including softer, smoother, more hydrated-feeling skin.
