Keratin protein is one of nature's most abundant materials, and the major component of the outermost layer of the skin. In a wound environment the keratinized layer of the skin is highly compromised. Biopolymers are well known to provide a favourable environment for wound healing, however, to date biopolymers derived from keratin protein have not been applied for the treatment of wounds. Substantial advances in keratin protein science have lead to the development of keratin protein biopolymer products suitable for application to a range of wound types. Cellular response to keratin biopolymers are very favourable when measured in vitro across a range of cell types important to the healing wound. In addition, animal trial data demonstrates accelerated healing for wounds treated with keratin dressings when compared to commercially available dressings.
