“Nighttime is when our skin’s natural regeneration processes are most active, making it the ideal moment to support hydration and renewal. In a clinical and dermatological study, participants wearing NATTCOLLAGEN™ sleepwear showed a significant increase in skin hydration (+40%) and improved skin refinement (pores), as confirmed by corneometry and Antera 3D measurements. The products were awarded the Dermatest 5-star seal for skin friendliness, underlining their excellent compatibility and efficacy.”
— Dr. med. Werner Voss, Specialist in Dermatology, Venereology, Allergology, Phlebology and Environmental Medicine

Natural & sustainable

Collagen that lasts, wash after wash. Crafted from botanic fibres with NATTCOLLAGEN™ Technology, Night Renew features marine collagen peptides bonded within the fibre itself. Because it’s not a surface coating, the collagen doesn’t simply fade over time — it’s locked into the polymer of the yarn prior to fabric production. Wood and pulp are sourced by Dagsmejan from sustainably managed forests and plantations.

Permanent infusion — The collagen peptides are part of the yarn, so they won’t wash out.
Naturally sourced — Derived from marine collagen peptides and integrated into the spinning solution during fibre production.

Eucalyptus fibres: Europe and Africa
Sleep technology: Switzerland
Knitting and dyeing of the fabric: Portugal
Garment making: Romania
