Silk and its Proteins: Fibroin, a wellness choice

fibrous proteins, nature at your fingertips

Silk is a completely natural fibre capable of providing wellness to our skin and body. Using clothing and/or components made of silk fibre means putting our body in contact every day with THE natural fibre par excellence, a technology laboratory capable not only of preventing any form of contact with harmful and damaging substances but also of providing natural elements (proteins, amino acids) of real wellness, absolutely compatible, curative and regenerative.

The main component of natural silk fibre, together with Sericin, is Fibroin, which with keratin, collagen, elastin and fibrinogen make up the group of fibrous proteins.

Sericin, fibroin, keratin, collagen, elastin and fibrinogen

In addition to sericin and fibroin, also keratin, collagen, elastin and fibrinogen make up the group of fibrous proteins.

Chemical composition of proteins

Proteins are elements with a physiological structure, with their own specific functionality. They are particularly important for living beings since they are the building blocks of all life processes. Chemically, proteins are macromolecules made up of amino acids. Although there are more than 300 amino acids in nature, only 20 are present in mammalian proteins since they are the only ones encoded by DNA. One protein is distinguished from the other based on a typical three-dimensional structure that determines its ability to perform specific biological functions.


globular proteins and fibrous proteins

Proteins are divided into two large families:

  • Globular Proteins that direct the physiological functions of the organism;
  • Fibrous Proteins that perform a support and protection function.

Fibrous proteins are of animal origin, insoluble in water, define the main structural elements of the organism and make up about one third of the total weight of the proteins in our body. We can find them in large quantities in the different layers of the epidermis:

  • fibrous proteinsKeratin, impermeable and insoluble in water, activates the external protection from harmful foreign elements present in the environment, restores the cells in the event of significant damage. It is the constituent protein of the outermost layers of the skin, hair and nails;
  • Elastin constitutes the connective tissue and gives elasticity to the tissues allowing them, if subjected to stretching and/or contraction, to return to their original shape;
  • Collagen creates a support, a model and a shape by composing the organic elements of the connective tissues (tendons, cartilages, deep layers of the skin);
  • Fibrinogen, a plasma protein responsible for blood clotting

The fibroin contained in Silk is a natural fibrous protein, a highly biocompatible and biodegradable polymer, consisting of carbon 47.6% Hydrogen 6.39% Nitrogen 18.33% and Oxygen 27.68%:

sericin and fibroin

  • highly biocompatible
  • biodegradable
  • resistant to microbial contamination
  • highly stable
  • protects the human epidermis
  • equipped with elements that assist the continuous cellular transformations.

Choosing natural silk fibres is THE wellness choice.
