Beauty ingredients
MIROS Proprietary Ingredient - PIKIÄ®

PIKIÄ®¹ is a proprietary micro-molecular vegan collagen² developed through a molecular design philosophy³. PIKIÄ possesses an amino acid sequence 100% identical to the collagen found in human skin⁴. These ultra-fine molecules penetrate throughout the stratum corneum, allowing for seamless affinity with the skin. Born from AI-driven design and precision fermentation, PIKIÄ®¹ offers a transformative skincare experience. MIROS is the first in Japan⁵ to formulate with PIKIÄ®, a breakthrough ingredient trusted by the world’s most prestigious luxury spas.

Rice Ferment Filtrate

Saccharomyces/Rice Ferment Filtrate is a traditional ingredient derived from domestically sourced rice, meticulously fermented with yeast of the Saccharomyces genus, and thoughtfully selected to elevate the full potential of PIKIÄ®¹.

Saccharomyces, a yeast long revered in Japanese sake brewing, has the unique ability to transform sugars into a diverse range of metabolites through fermentation. When paired with rice, this process yields a refined, multi-layered composition unique to fermentation.

Saccharomyces/Rice Ferment Filtrate not only enhances the performance potential of PIKIÄ®¹, but also encapsulates reverence for nature and the enduring tradition of fermentation.

Botanical Extracts

White Lavender

A rare, domestically sourced extract of white lavender cultivated in cold climates. With its delicate, refined aroma, it helps maintain the skin’s natural balance, guiding it toward a luminous, translucent radiance.

Skin-Conditioning Ingredient / INCI: Lavandula Angustifolia (Lavender) Flower Extract

Yukinoshita

Yukinoshita is a domestically sourced extract derived from Saxifraga stolonifera, a plant that thrives in pristine mountain landscapes. It helps prevent skin roughness while supporting fresh, lasting hydration, guiding the skin toward a clear, luminous translucence—evoking the quiet vitality that endures beneath the snow.

Saxifraga Extract (Skin-Conditioning Ingredient)

Irohamomiji

An enduring symbol of the four seasons, Irohamomiji is a domestically sourced extract from Japanese maple leaves. It refines the skin’s condition and helps combat roughness, revealing a clear, composed luminosity—quietly echoing the harmony of nature’s transitions.
