In the ever-evolving world of beauty, some of the most effective skincare secrets are deeply rooted in tradition. Rice, long revered in Japanese culture, stands as one such timeless gem. In May 2024, we introduced our star ingredient, GlucoskinX3, marking a revolutionary step forward in modern skincare. This advanced formulation draws on centuries of Japanese beauty rituals to reveal skin that is radiant, hydrated, and visibly healthier.
The Power of Rice in Skincare – Glucoskinx3’s Secret for Radiant, Hydrated Skin

From Fermented Sake to High-Performing Ingredient
For generations, Japanese cosmetic care has celebrated the nourishing properties of rice. Now, GlucoskinX3 elevates that heritage to a new level of performance. At the core of this innovation is GlucoskinX3—derived through a cutting-edge extraction process from fermented rice (Onna Sake Kazu), sourced from a Kyoto sake brewery with over 300 years of history.
Traditionally used in Japanese cuisine, sake lees have gained recognition for their extraordinary skincare benefits. Rich in saccharides, amino acids, and glucosylceramides—a powerful compound that bonds ceramides and sugars—this ingredient delivers intensive hydration and helps strengthen the skin's natural barrier.

The Skincare Benefits of Glucoskin
Infused with powerful glucosylceramides, GlucoskinX3 offers multi-level skin benefits:
- Reinforces and strengthens the skin’s protective barrier
- Deeply moisturizes, improving hydration from within
- Refines texture and promotes a clearer, more even complexion
Together with Triple Collagen and La Foux Spring Water, GlucoskinX3 has become a signature active within our Saho rituals—designed to restore, rebalance, and rejuvenate.
