Shiseido’s discovery on eyelash growth

Shiseido Has found out an Ingredient That Helps Eyelashes Grow Longer : Zizyphus Jujuba Fruit Extract Promotes the Growth Rate of Eyelashes

Shiseido Research Center has been specifically and intensively studying lashes. Through this research, it was discovered that length of eyelashes is dependent on their growth rate. This led Shiseido to pursue more research, to find the cosmetic ingredient that supports beautiful lashes.

This investigation led Shiseido to make a new finding that Zizyphus jujuba fruit extract* is highly effective to help eyelashes grow longer through promoting their growth rate.
These research results had been reported at the 13th Annual Meeting of the Japanese Society of Anti-Aging Medicine in Yokohama, June 28 to 30, 2013.

Shiseido’s Research: Lash Growth

Every kind of hair has its own timeframe.

While the mechanism behind hair growth cycle is exactly the same for lashes, scalp hair, and body hair, Shiseido’s research shows that the lenght of the hair life cycle for lashes is extremely short – just 4 months. The growth phase is also very short, only lasting 39 days.

After examining more than 250 women’s eyelashes, Shiseido researchers concluded that lenght of eyelashes is highly dependent on their growth rate.
