Silk production has empowered Asian women for over 4 millennia. They have benefited from harvesting cocoons, creating thread, and designing and wearing exquisite garments.

Chinese, Japanese and Thai women developed

ways to obtain silk protein extracts.

The most common technique was to

scrub wet cocoons on their faces.

 

They discovered that handling silk cocoons had remarkable effects on their skin. The anti-aging, rejuvenating, and wound healing properties were apparent. Long before science identified the proteins, women learned to apply sericin and fibroin without complex technologies and extraction methods. Over time, artisans created creams, ointments, and sericin-enrobed tissues.

Identified in the late 1950s, science has confirmed the properties of sericin and fibroin proteins and established the potential of the molecules. Challenges to large-scale extraction and production for cosmetic or medical use prevented major brands from exploring these proteins. Although some brands developed the technology and processes to extract silk proteins, it remained a niche market.

THE VIRTUES OF SILK

A WEALTH OF PROPERTIES

Sericin and fibroin are single, natural proteins with proven scientific applications for cosmetic, biomedical, pharmaceutical and industrial use.

TYPICAL USES

  • Skin creams: anti-aging, erase wrinkles, UV-blocking, prevents formation of age spots

  • Hair care: moisturizing and repair; safeguarding effect

  • Gloves with dermatologic properties to treat skin wounds

  • Antimicrobial air filters and antimicrobial textiles, as sericin absorbs moisture

  • Edible supplements: as an antioxidant and for protein replacement

  • Serum: for tissue culture, tissue scaffolding, in vitro research

Silk production has empowered Asian women for over 4 millennia.

Moisturizing

  • An excellent moisturising agent that restores amino acids

  • Increased hydroxyproline level; a major component of collagen

  • Decreased amount of water evaporating through the skin - Trans Epidermal Water Loss (TEWL)

Antibactericidal

  • As a coating on nylon and polyester fibers with strong potential to be used for indoor air filters to reduce the amount of toxic free radicals, fungi, and Micrococcus-type  bacteria

Anti-wrinkle 

  • Anti-wrinkle effect thru collagen stimulation.

  • Sericin induces an improvement of the cutaneous relief and a decrease in deep wrinkles

  • It enhances elasticity of skin and has shown anti-wrinkle and anti-aging effects because of its collagen promoting activity

Rejuvenating

  • Rejuvenation thru reduction of lipid and glucose absorption.

  • Silk sericin can stimulate cell migration through protein phosphorylation

  • Activation of collagen production both in vitro and in vivo

  • Silk protein sericin-based nanofibrous matrices fabricated by electrospinning exhibit appropriate properties required for skin tissue regeneration

  • In clinical studies, sericin has exhibited biological activities such as cell proliferation

Hair Repair

  • Sericin may be applied to cosmetic formulas for hair care, promoting a significant increase in hair gloss, volume reduction, besides improving softness and ease of combing, abating roughness and repairing damage, probably due to the sealing of cuticles

  • Sericin, when applied to hair dye formulas, promote maintenance of hair coloring

Biomaterial

  • Sericin protein can be used to fabricate functional fiber

  • Used as an improving reagent or a coating material for natural and artificial fibers, fabrics, and articles

  • Wound healing properties and can be used as wound healing covering material in the form of film

  • Ideal polymer for drug delivery

  • Can be cross-linked, copolymerized, and blended with other macromolecular materials, especially artificial polymers, to produce materials with improved properties

  • Excellent potential for dissolvable micro-needles
