“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.”

Night Renew is crafted from botanic fibres combined with NATTCOLLAGEN™ Technology, where marine collagen peptides are permanently embedded inside the fibre itself. Unlike surface coatings that can fade or wash away, these collagen peptides are locked into the polymer structure of the yarn before the fabric is even knitted. Dagsmejan sources wood and pulp 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.
