Keratin is a family of proteins that are among the most important and versatile that nature has ever produced.

From structures built for toughness and protection, such as hair, nails, and skin, to subtle bioactive mediators carrying important peptides that tell injured skin cells to heal and grow, keratin is nature's material of choice due to superior physical properties, and a crucial biological activity.

From within every cell of human and animal bodies, the definitive combinations of amino acids and fibrous structures that characterize keratins are used to build strong, healthy tissues, and encourage the development of surrounding strong, healthy tissue.

The ability of keratin to provide physical structure and biological function is due to the unique form that keratins have evolved for this purpose.

Introducing Replicine™

Replicine™ Functional Keratin® is the first real keratin technology that captures the native form and function of keratin proteins, providing benefit across a broad range of personal care, health care, nutritional and industrial applications.

All previous approaches to isolating keratin proteins for commercial use have managed to destroy the fundamental keratin protein structure required to deliver function.

The unique patented approach the team at Keraplast has developed to extract Replicine™ Functional Keratin® ensures the form of keratin proteins is maintained and delivers function and benefit as a result.

Replicine™ has evolved from decades of scientific research into how to capture the functional properties of keratin proteins and deliver them for consumer benefit in practical applications.

New Zealand Origins

Replicine™ Functional Keratin® is gently extracted from pure New Zealand wool. Find out more about the origins of Replicine™ Functional Keratin®.
