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

They discovered that handling silk cocoons had remarkable effects on their skin, learning how to apply sericin without complex technologies and extraction methods, and enjoying its anti-aging, rejuvenating and wound healing properties. Artisans have created creams, ointments, and sericin-enrobed tissues for centuries.

Research has confirmed the properties of the sericin protein and established the potential of the molecule. However, challenges to large-scale production for cosmetic or medical use prevented large brands from exploring sericin. A limited number of niche players were able to develop the technology and processes and offer a product that met industry standards.

Chinese, Japanese and Thai women have developed ways to obtain sericin extracts.


The most common technique was to scrub wet cocoons on their faces.


Sericin is a single, natural protein. Due to its biochemical properties, it has many scientifically proven applications for cosmetic, medical, pharmaceutical and industrial uses.


  • Decrease in skin impedance

  • Increased hydroxyproline level; a major component of collagen

  • Decreased levels of Trans Epidermal Water Loss (TEWL); the amount of water passing through the skin and evaporating

  • Prevents water loss from the upper layer of the skin

  • Increase in the intrinsic moisturization of skin by restoration of the amino acids and its occlusive effect

  • Sericin is an excellent moisturising agent used in cosmetics industry


  • Coated onto 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 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


  • 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


  • Sericin protein can be used to fabricate functional fiber

  • The protein is also used as an improving reagent or a coating material for natural and artificial fibers, fabrics, and articles

  • Sericin has been found to possess wound healing property and can be used as wound healing covering material in the form of film

  • Ideal polymer for drug delivery

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

  • Sericin has great potentials for dissolvable micro-needles


Leveraging the above proven claims, the typical products can include:


  • 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
