Salon-grade damage repair in 4 minutes!

These impressive results are made possible by a proprietary delivery technology that enhances ingredient absorption by 50%, allowing peptides and proteins to penetrate deep into the hair cortex where real repair begins. The formula features low molecular weight repair peptides that are 8 times smaller, allowing for 7 times faster penetration compared to conventional treatments. This technology strengthens, smooths and protects the hair, all without weighing it down.
Rooted in the principles of J-Beauty, the Kiseki Leave-in Masque embodies NatureLab.TOKYO’s unique blend of traditional Japanese rituals and advanced molecular science. Featuring Core Absorption Technology, the masque penetrates deeply into the hair cortex to strengthen hair structure.

The Power of Peptides: Milk Thistle Seed Extract, Nature’s Molecular Healer
At the heart of Kiseki is Milk Thistle Seed Extract, a sustainable, vegan alternative to keratin. With a 50-70% peptide concentration and an amino acid profile similar to keratin, this powerhouse ingredient has been used in herbal medicine for over 2,000 years — and now plays a vital role in hair repair.
Its low molecular weight peptides penetrate deep into the hair’s core to stabilise and repair keratin structures, strengthening strands, reducing breakage and protecting against UV, pollution and heat damage. Sourced from the upcycled by-product of milk thistle oil production, it reflects NatureLab. TOKYO’s commitment to clean, conscious beauty.
Supporting ingredients like pea, rice and soy proteins, upcycled Japanese green tea seed oil and lotus flower extract further fortify, hydrate and protect, leaving hair visibly smoother and more resilient.
“We’re excited to launch the Kiseki Masque, a revolutionary product that embodies the essence of J-Beauty,” says Keigo Tiger Hishiya, CEO of NatureLab.TOKYO. “With our innovative molecular repair technology and traditional Japanese ingredients, Kiseki offers effective solutions for all hair types, restoring health and vitality at the core.”
A Sensorial Experience Inspired by Japanese Heritage
Kiseki is more than a treatment — it is a ritual. The masque is infused with a fragrance inspired by hinoki wood (Japanese cypress), layered with sacred incense, pressed paper, fresh cypress bark, subtle citrus and woodsy lavender. This gender-neutral scent evokes the serenity of a traditional Kōdō ceremony and the restorative calm of forest bathing, transforming haircare into a mindful, uplifting experience.
Like all NatureLab. TOKYO products, Kiseki is formulated without parabens, sulfates, phthalates, silicones and over 1,300 ingredients banned by the EU, ensuring a clean, cruelty-free formula.How to Use the Kiseki Molecular Repair Leave-In Hair Masque
