Natural human-type ceramide


It has been over 100 years since the renowned skin-brightening ingredient, kojic acid was discovered from koji mold, Aspergillus or yzae, the naturally occurring culture that has been used for centuries in Japan to make soy sauce, sake and miso.

Genunie R&D in Japan is proud to announce the discovery of our revolutionary ceramides from Koji. The world’s first Natural human-type ceramide created through the traditional Japanese soy sauce fermentation process is safe, effective and stable.

What are Ceramides?

Ceramides are biogenic components found in the skin’s outer layer. Its function is to protect against moisture loss to keep skin both youthful and supple. The loss of ceramides causes aging skin permeable to moisture, leaving skin dry.


Genunie R&D scientist has developed a unique process to extract Natural human-type ceramide from the byproduct of the centuries-old soy sauce making process.

6 Key Characteristics

  • Increase skin’s water-retention capacity
  • Barrier repair and cell regulation
  • Protect skin and prevent moisture loss
  • Improve skin texture
  • Renew, rebuild and restore aging skin
  • Reduce roughness and dryness
“Ceramide loss is a major contributor to wrinkles. Natural “human-type” ceramide is the key to maintaining both healthy and youthful-looking skin.” -K. Yunoki, PhD

Before and after

Genunie R&D clinical studies show that applying their Natural human-type ceramide to the skin can greatly improve skin conditions such as eczema, atopic dermatitis, and psoriasis.
The largest organ in the human body is the skin, with the outermost layer being the stratum corneum. Ceramide accounts for 50% of the intercellular lipid matrix, the “glue” which binds the SC, the foremost protective barrier which protects underlying tissue from dehydration, infection and external injury.
