Efficacy of Fibroin
I.The skin care effect of Fibroin

(1) It has the functions of natural moisturizing and skin nourishing
(2) Possessing the action of inhibiting melanin production,
(3) Promoting the regeneration of skin tissue, guard against chapping and chemical damage
(4) Inhibiting the skin cancer
(5) Silk protein also possesses the function of antioxidant
(6) Silk protein also possesses the function of antioxidant

II. The hair-caring, hair-nourishing and hairdressing functions of silk protein.

Silk protein's hair-caring function depends on the absorbency, absorptivity, film-forming ability and moisturizing type it received by hair. Compared with other protolysates (collagen, bone collagen, glutin and so on), the biggest feature of fibroin is that it is easy to be absorbed by the hair.

III. The Nutritional Function of Fibroin Food

Silk protein contains 18 types of amino acid, over 90 percent of which can be absorbed by human body. Its percentage of amino acids which are necessary to human body reaches more than 17 percent, higher than normal food. Therefore, it is a very good way of amino acid supplements to add the fibroin into the food. Japan began the research of turning silk into food as early as 1983.
