Invisible and Peelable Silk Fibroin Film
The “Second Skin”–This product is a white, viscous solution which can be smeared easily on surfaces, dry quickly and turn into an elastic, long-lasting and transparent layer.
Brand Name: Fancci
Alternative Name: second skin
This product is a white, viscous solution which can be smeared easily on surfaces, dry quickly and turn into an elastic, long-lasting and transparent layer. No further treatments are needed. Once formed on skin, it may function as an invisible but peelable mask that protects the skin from UV expose, keep moisture, deliver loaded active ingredient and reduce wrinkles due to the skin-like mechanical properties.
The natural silk fibroin and most other agents used in the product are of those used in our medical products, thus biocompatible, safe and manufactured and quality-controlled according to the FDA and CFDA standards of pharmaceutical excipients. The product can be used as a base material for further formulating different products in areas like skincare cosmetics, topical and transdermal drug delivery, and wound healing, etc.
Parameter and properties
Major Components: large molecular weight silk fibroin protein
Appearance: white, opaque, semi-colloidal solution
Viscosity: 1500-4000 Pa.s
(1) The product consists of silk fibroin (major component) and other cosmetic excipients (minor components), which can rapidly form an invisible and peelable film on the skin upon air-drying and curing. Due to its naturally derived components, biocompatibility and mechanical strength that mimics human skin, the film formed can remain close attachment to the skin for a long period of time without any irritation and foreign-body feeling. You can easily peel or wash it off the skin without any difficulty and pain.
(2) The large molecular weight silk fibroin is a new biodegradable material that has been proved to be non-immunogenic and non-toxic by animal studies and that has recently been listed as one of the major subjects in the 2017 National Key Research and Development Program of China together with collagen materials. The material processing of silk fibroin is green, without using toxic chemicals and special equipment. The composition of 18 natural amino acids of silk fibroin also benefits functional encapsulation and stabilization of bioactive molecules.
(3) Our data showed that the product can absorb UV light, thus providing function of sunscreen when being applied on skin.
(4) The product also exhibits ideal breathability and prevention of water loss, thus having moisturizing effect and comfortable feeling when applied on skin.
