J-Premier Extract 31
Natural ingredients made using sake and fermentation techniques
The power of two materials
Increased moisturizing power, firmness and elasticity
- Material features
High in skin-beautifying ingredients α-EG* and amino acids
It is a natural cosmetic ingredient.
*Contains 2 to 5 times more α-EG than regular sake - Advantages
Increases skin's moisturizing ability.
Gives skin firmness and elasticity.
- ●The power of rice fermentation liquid
High content of skin-beautifying ingredient α-EG - Sake has been known for its skin-beautifying effects since ancient times. The main ingredient that has been attracting attention for its skin-beautifying effects is
This is α-EG.
At Ozeki, α-EG promotes collagen production and inhibits its breakdown, promotes elastin production,
We found that it has effects such as promoting cell proliferation.
JP31 contains 2 to 5 times more α-EG than sake.
In recent years, it has been reported that drinking α-EG increases collagen density, making it an ingredient that is attracting increasing attention. - ● Two-stage fermentation of sake lees ~ Increased amino acids ~
- Sake lees are rich in amino acids derived from rice, koji, and yeast. Ozeki has developed a technology to increase the amino acid content by fermenting sake lees again with yeast.
Beautiful skin care program
Collagen, elastin, and hyaluronic acid play important roles in maintaining the moisture, firmness, and elasticity of the dermis. Aquaporins are involved in water absorption. When these are reduced, it can cause skin problems such as wrinkles and sagging.
- moisture
- hyaluronic acid
- Found in the gaps between collagen and elastin tissues, it is a jelly-like mucopolysaccharide with excellent water retention properties.
- aquaporins
- A protein involved in the uptake of water into cells.
It plays an important role in keeping the skin moisturized.
- Firmness / Resilience
- collagen
- It is made up of fibrous proteins woven into a mesh-like structure.
- Elastin
- Binds collagen knots. Elastic fibers.
- 線維芽細胞
- Produces the substances listed above that keep your skin healthy.
Increased moisturizing power
Promotes hyaluronic acid and aquaporin production
[in vitro]
- The expression of the HAS2 gene, which is involved in hyaluronic acid synthesis, and the AQP3 gene, which is involved in aquaporin synthesis, increased.
- The amount of hyaluronic acid produced by fibroblasts increased.
Increased skin firmness and elasticity
Promotes collagen production and inhibits degradation/
Promotes elastin production [in vitro]
- The expression of ELN genes involved in elastin production was increased.
- The expression of COL1A1 and COL1A2 genes involved in type I collagen synthesis was increased.
- The expression of the MMP1 gene, which is involved in the breakdown of collagen, was suppressed.
- Increased production of type I collagen from fibroblasts.
Increases firmness and elasticity in human skin
[in vitro]
