Keywords: Abstract:
Silk cocoon, It’s said that beauty lies in the eyes of beholders, but now it’s age to
Fibroin, Sericin maintain the external and internal beauty of personality. Regarding
the maintenance of beauty everyone is very protective regarding their
skin. For instant better effects we use chemical-based beauty products.
In this era of chemicals Silk cocoon facial is boon to human beings. Silk
cocoon is mainly made up of two proteins. One is fiber protein that is
fibroin and other is adhesive glue protein that is sericin. Sericin is an
amazing protein containing 18 amino acids. Sericin acts as a thin film
over the face sealing in moisture to keep skin hydrated. It contains
highly hydrophobic amino acids which has antioxidants potential.
Therefore, it has high demand in cosmetic industry. The moisturizing
power allows indications as a therapeutic agent for wound healing,
stimulating cell proliferation, protection against ultraviolet radiation
and formulating creams and shampoos.

Introduction:
There is one worm from phylum Arthropoda, Class Insecta called Bombyx mori, which is reared
for production of silk. In India four types of silk are reared i.e Mulberry Silk, Eri silk, tasar silk,
muga silk. These silks are obtained from the silk cocoon. Cocoon is a material which is composed
of thin and continuous strands of fibers. Cocoon is natural silk composite with non-woven
structure made of continuous silk fiber. These fibers are nothing but the production of Proteins
Of silk glands of silkworm. Silkworm's stage of pupa feeds on Mulberry leaves. Silkworm weaves
a net around itself to keep itself alive in pupa stage. The secretions produce by the salivary glands
ultimately turns into silk. Two major proteins are present in the Cocoon named fibroin and
sericin. Fibroin is the central fibrous protein and sericin is the globular protein. Sericin is the sticky
part that envelopes the fibers and coheres them together. Sericin has numerous properties like
antitumor anti-ageing anti-wrinkle. Sericin is rich in four amino acids that are Serin, glycine,
aspartic acid and threonine. These four amino acids have various function which results in
healthy skin. serin and threonine functions as natural moisturizing factors which act as water
binding molecules. These proteins also help in replenishing skins barrier function. Glycine
improves the visible signs of ageing, increases production of collagen and strengthens the skin
and promotes skin repair and regeneration. Aspartic acid naturally balances the pH of skin.
Cocoon is package of all required beauty products. This sericin has excellent moisture absorbance
and anti-microbial property The silk peptide has good therapy effects for several dermatosis.
Such as skin cracks and skin burns. Sericin forms a substantive protective anti-wrinkle film on
the skin surface.
