(as Sodium Hyaluronate)
*Skin hydration

What is Hyaluronic acid?

  • ・Isolated from the vitreous of bovine eyes in 1934.
  • ・A type of mucopolysaccharide composed of glucuronic acid and N-acetylglucosamine with maximum molecular weight of up to 7,000,000 Dalton.
  • ・Retain high moisture, elasticity, biological compatibility.
  • ・Distributed in the human body such as skin, synovial fluid and in the eyes (vitreous body).
  • ・High concentration of Hyaluronic acid exists in the inner layer of the skin (epidermis/dermis).
  • ・Acts to hydrate and lubricate within the skin.





Dermis won't
retain moisture
leading to dry skin!

  • ・Hyaluronic acid and collagen are important substances for maintaining healthy skin.
  • ・Hyaluronic acid decreases as we age. Oral intake of Hyaluronic acid helps to replenish the lost Hyaluronic acid.

The Mechanism of Hyaluronic acid

  • ・Oral ingestion of Hyaluronic acid is not decomposed in the small intestine by digestive enzymes.
  • ・Decomposed and absorbed by the intestinal bacteria in the large intestine into Oligo Hyaluronic acid.
  • ・Oligo hyaluronic acid is absorbed into the host body and transferred into the skin through blood.
  • ・Leads to activating the collagen metabolism and fibroblast to promote the production of Hyaluronic acid.
